Prevention of osteoporosis in population older than 50 from Colombia: An intervention model from a nutrieconomics perspective

Introduction: Osteoporosis is a chronic disease characterized by a decrease in the density of bone mass, making bone more porous, less resistant and of lower quality than normal bone. This leads to the deterioration of its microstructure, making the bone more fragile and therefore increasing the risk of fracture. It has been found that high concentrations of Lactobacillus and Bifidobacterium promote the absorption of minerals such as calcium, magnesium, and phosphorus and thus increase mineral density. Due to the great social and economic impacts of osteoporosis, it is necessary to develop interventions that can be easily adopted at the population level, improving the quality of life of individuals without significantly affecting the health system. Objective: Assessing the impact of increased dairy consumption on the Colombian population diagnosed with osteoporosis between 2015 and 2020 through the simulation of the potential impact fraction (PIF). Methods: Using data from the Integrated Social Protection Information System (SISPRO) and National Nutritional Situation Survey (ENSIN), the incidence, the frequency of milk consumption, the potential impact fraction (PIF), and disability-adjusted life years (DALYs) were estimated. Results: A total of 63,640 cases of osteoporosis were identified. The highest incidence was observed in 2019. Seventeen food groups were identified in the ENSIN, and the most frequent products consumed by respondents over 50 years of age were milk, cheese, and yogurt. The PIF was then analysed, with a calcium intake of 600 mg/ day, and a significant difference in the decrease in the number of cases was observed. In 2019, a higher estimated DALY loss of 9.9 was observed. In women, years of life lost due to fractures were the highest in the 65-69 age group. In men, they were highest in the 75-79 age group. Discussion: We observed that the departments with the highest consumption of dairy products were the capital of the country and regions where dairy products factories are located. It was not possible to establish an association between socioeconomic strata and low dairy intake. Nevertheless, some authors have proposed that westernization of diets and low income reduce access to fresh fruits and milk derivates. Conclusion: Years lost due to disability increased in the population over 60 years of age. In the PIF analysis, a decrease in cases was observed when the population increased consumption of dairy products.

Introducción: La osteoporosis es una enfermedad crónica caracterizada por una disminución de la densidad de la masa ósea que hace que el hueso sea más poroso, menos resistente y de menor calidad que el hueso normal. Esto conduce al deterioro de su microestructura, por lo que el hueso se hace más frágil y, por lo tanto, aumenta el riesgo de fractura. Se ha encontrado que las altas concentraciones de Lactobacillus y Bifidobacterium promueven la absorción de minerales como calcio, magnesio y fósforo y, por lo tanto, aumentan la densidad mineral. Debido a los grandes impactos sociales y económicos de la osteoporosis, es necesario desarrollar intervenciones que puedan ser fácilmente adoptadas a nivel poblacional con el fin de mejorar la calidad de vida de los individuos sin afectar significativamente el sistema de salud. Objetivo: Evaluar el impacto del aumento del consumo de lácteos en la población colombiana con diagnóstico de osteoporosis entre 2015 y 2020 mediante la simulación de la fracción de impacto potencial (PIF). Materiales y métodos: Estudio ecológico realizado en adultos mayores de 50 años con diagnóstico de osteoporosis. A partir de los registros del Sistema Integrado de Información de Protección Social (SISPRO) y la Encuesta Nacional de Situación Nutricional (ENSIN), se estimó la incidencia, la frecuencia de consumo de leche, el PIF y los años de vida ajustados por discapacidad (AVAD). Resultados: Se identificaron un total de 63 640 casos de osteoporosis en SISPRO, la mayor incidencia se observó en 2019. Se establecieron 17 grupos de alimentos en la ENSIN, los productos más frecuentes consumidos en población mayor de 50 años fueron leche, queso y yogur. En el cálculo del PIF se encuentra que con una ingesta de calcio de 600 mg/día se reduciría significativamente el número de casos. En 2019 se observó una mayor pérdida estimada de AVAD de 9,9. En las mujeres, los años de vida perdidos debido a fracturas fueron más altos en el grupo de edad de 65 a 69 años. En los hombres, fue más alta en el grupo de edad de 75-79 años. Discusión: Observamos que los departamentos con mayor consumo de productos lácteos fueron la capital y las regiones donde se encuentran las fábricas de productos lácteos. No fue posible establecer una asociación entre los estratos socioeconómicos y la baja ingesta de lácteos. Sin embargo, algunos autores han propuesto que la occidentalización de las dietas y los bajos ingresos reducen el acceso a frutas frescas y derivados de la leche. Conclusión: Los años perdidos por discapacidad aumentaron en la población mayor de 60 años. En el análisis PIF, se observó una disminución en los casos (reducción de 2329 casos/ año) cuando la población aumentó el consumo de productos lácteos.

Participação plurissocial para aumentar a inclusão e a assertividade nas tomadas de decisão em saúde relacionadas a tratamentos da osteoporose / Pluri-social participation to increase inclusion and assertiveness in health decision-making related to osteoporosis treatments

Embora as fraturas por fragilidade sejam importantes detratoras de qualidade de vida relacionada à saúde, aumentando a morbimortalidade e acarretando alto impacto clínico, psicossocial e econômico, elas são pouco valorizadas e negligenciadas por médicos e até mesmo por pacientes. Além disso, os critérios de priorização para avaliação de novas tecnologias, em geral, não consideram critérios além dos financeiros para uma tomada de decisão mais inclusiva e assertiva para o tratamento da população de mais alto risco de fratura. Assim, este artigo visa revisitar alguns diferentes pontos de vista e trazer uma reflexão sobre critérios e prioridades na osteoporose. Para isso, foi considerada a perspectiva de múltiplos atores no processo de tomada de decisão em saúde, bem como analisadas as falhas na atenção a uma doença de alta prevalência e que, além do grande impacto econômico gerado para a sociedade, causa repercussões emocionais, incapacidade gerada por fraturas e medo de novas quedas ou pequenos traumas.

Although fragility fractures are important detractors of health-related quality of life, increasing morbidity and mortality and causing a high clinical, psychosocial, and economic impact, they are undervalued and neglected by physicians and even patients. In addition, prioritization criteria for evaluating new technologies, in general, do not consider criteria other than financial ones for a more inclusive and assertive decision-making for the treatment of the population at higher risk of fracture. Thus, this article aims to revisit some different points of view and bring a reflection on criteria and priorities in osteoporosis. For this, the perspective of multiple stakeholders in the health decision-making process was considered, as well as the failures in the care of this highly prevalent disease that, in addition to the great economic impact generated for society, causes emotional repercussions, disability generated by fractures and fear of further falls or minor trauma.

Use of the SARC-F Score as an Aid in Fragility Fractures Prevention / O uso do escore SARC-F como auxiliar na prevenção de fraturas por fragilidade

Abstract Objective The present study aimed to relate the strength, assistance with walking, rising from a chair, climbing stairs, and falls (SARC-F) score with the presence or absence of fragility fracture in the population over 60 years of age. Methods The risk of sarcopenia was determined through the application of the SARC-F questionnaire, and the patients were divided into 2 groups, according to the occurrence or not of fragility fracture (n = 100). Results Thirty-two cases of distal radius fractures and eighteen cases of proximal femur fractures were identified. A higher score on the SARC-F is determinant between having or not a fragility fracture, estimating that for each point in the score there is a 70% increase in the chance of a patient having a fracture, regardless of age, gender, and body mass index (BMI). Conclusion There was a direct correlation between a higher score on the SARC-F and an increase in the chance of fragility fracture.

Resumo Objetivo O presente estudo teve como objetivo relacionar o escore strength, assistance with walking, rising from a chair, climbing stairs, and falls (SARC-F) com a presença ou não de fratura por fragilidade na população acima de 60 anos. Métodos O risco de sarcopenia foi determinado por meio da aplicação do questionário SARC-F, sendo os pacientes divididos em 2 grupos, de acordo com a ocorrência ou não de fratura por fragilidade (n = 100). Resultados Foram levantados 32 casos de fratura de rádio distal e 18 casos de fratura de fêmur proximal. Uma maior pontuação no SARC-F determina bem entre ter ou não ter fratura por fragilidade, estimando que a cada ponto a mais no escore há um acréscimo de 70% na chance de o paciente ter fratura, independentemente da idade, sexo e índice de massa corporal (IMC). Conclusão Houve correlação direta entre uma maior pontuação no SARC-F e aumento na chance de fratura por fragilidade.

Robot-assisted percutaneous vertebroplasty combined with pediculoplasty in treating symptomatic chronic thoracolumbar osteoporotic vertebral fracture without neurological impairment / 中华创伤杂志

Objective:To compare the efficacy of robot-assisted and conventional fluoroscopy-guided percutaneous vertebroplasty (PVP) combined with pediculoplasty in treating symptomatic chronic thoracolumbar osteoporotic vertebral fracture (SCOVF) without neurological symptoms.Methods:A retrospective cohort study was used to analyze the clinical data of 120 patients with thoracolumbar SCOVF without neurological symptoms, who were admitted to Honghui Hospital Affiliated to Xi′an Jiaotong University from January 2015 to January 2020. The patients included 34 males and 86 females, aged 63-85 years [(72.9±5.7)years]. All patients were treated with PVP combined with pediculoplasty. A total of 87 patients were treated with robot-assisted and C-arm X-ray machine guided puncture (robot group) and 33 patients with C-arm X-ray machine fluoroscopic-guided puncture (conventional group). The operation time, amount of bone cement injection and puncture accuracy were compared between the two groups. The results of vertebral body index, Cobb angle, visual analogue scale (VAS), and Oswestry disability index (ODI) were also compared before operation, at 1 day and 1 year after operation and at the final follow-up. Complications such as bone cement leakage and displacement were observed.Results:All patients were followed up for 24-36 months [(29.4±3.4)months]. The operation time was (85.2±10.5)minutes in the robot group, significantly longer than (37.2±3.7)minutes in the conventional group ( P<0.01). The amount of bone cement injection was (5.0±0.7)ml in the robot group, significantly less than (5.3±0.8)ml in the conventional group ( P<0.05). The puncture accuracy in the robot group was 95.4% (83/87), significantly higher than 81.8% (27/33) in the conventional group ( P<0.01). There were no significant differences in vertebral body index, Cobb angle, VAS or ODI between the two groups before operation (all P>0.05). The values of vertebral body index were 87.1±4.5, 86.9±4.3, 86.8±4.3 in the robot group at 1 day after operation, 1 year after operation and the final follow up, respectively, which were significantly higher than 83.6±4.4, 84.1±3.8, 84.4±3.9 in the conventional group (all P<0.01). There were no significant differences in Cobb angle or ODI between the two groups at 1 day after operation, 1 year after operation or the final follow-up (all P>0.05). The values of VAS were (2.9±1.0)points, (1.8±0.7)points, (1.8±0.7)points in the robot group at 1 day after operation, 1 year after operation and the final follow-up, respectively, which were significantly lower than (4.4±1.1)points, (3.1±0.8)points, (3.0±0.9)points in the conventional group (all P<0.01). The bone cement leakage occurred in 7 patients in the robot group [8.0%(7/87)] and in 10 in the conventional group [30.3%(10/33)] ( P<0.01). No delayed bone cement displacement [0.0%(0/87)] occurred in the robot group from 1 day after operation to the final follow-up, but 3 patients [9.1%(3/33)] were noted in the conventional group ( P<0.05). Conclusion:Both robot-assisted and conventional fluoroscopy-guided PVP combined with pediculoplasty have satisfactory effect for SCOVF patients without neurological impairment, but the robot-assisted one has the advantages of higher puncture accuracy, more satisfactory vertebral height recovery, more rapid pain relief, lower incidence of bone cement leakage and effective avoidance of cement displacement.

Efficacy comparison of robot-assisted and free-hand long segment screw fixation combined with wedge osteotomy in the treatment of type IV chronic symptomatic osteoporotic thoracolumbar fractures / 中华创伤杂志

Objective:To compare the clinical efficacies of robot-assisted and free-hand long segment screw fixation combined with wedge osteotomy in the treatment of type IV chronic symptomatic osteoporotic thoracolumbar fractures (CSOVCFs).Methods:A retrospective cohort study was conducted to analyze the clinical data of 72 patients with type IV CSOVCFs who were admitted to Honghui Hospital of Xi′an Jiaotong University from May 2019 to December 2021, including 22 males and 46 females; aged 61-82 years [(71.2±12.3)years]. Fracture segments were located at T 11-T 12 in 37 patients and at L 1-L 2 in 31. A total of 32 patients were treated with robot-assisted long segment screw fixation combined with wedge osteotomy (robot group) and 36 with free-hand long segment screw fixation combined with wedge osteotomy (free-hand group). The operation time, intraoperative bleeding volume, dosage of radiation exposure, intraoperative needle adjustment, time of single pedicle screw placement and accuracy of pedicle screw placement were compared between the two groups. The kyphotic Cobb angle, sagittal vertical axis (SVA), thoracic kyphosis (TK), lumbar kyphosis (LL), visual analogue scale (VAS) and Oswestry disability index (ODI) were measured preoperatively, at 3 days postoperatively and at the last follow-up. The incidences of facet joint violation, deviation in guide needle placement, cerebrospinal leak and proximal junctional kyphosis (PJK) were observed. Results:All patients were followed up for 12-26 months [(18.2±5.1)months]. The operation time and time of single pedicle screw placement showed no significant differences between the two groups (all P>0.05). The intraoperative bleeding volume was (502.5±58.3)ml in the robot group, less than that in the free-hand group [(690.2±45.9)ml]. The dosage of radiation exposure was (32.6±10.8)μSv in the robot group, lower than that in the free-hand group [(48.6±15.2)μSv]. The intraoperative needle adjustment was (2.1±0.3)times in the robot group, higher than that in the free-hand group [(20.7±5.8)times], and the accuracy of pedicle screw placement was 99.7% in the robot group, less than that in the free-hand group (91.8%) (all P<0.01). Compared with pre-operation, the kyphotic Cobb angle, SVA, TK and LL were significantly improved in both groups at postoperative 3 days and at the last follow-up (all P<0.05). Compared with postoperative 3 days, the kyphotic Cobb angle, SVA and TK were increased at the last follow-up within the two groups, but with no significant differences (all P>0.05). Compared with postoperative 3 days, the LL was decreased within the two groups at the last follow-up, but with no significant differences (all P>0.05). The VAS and ODI in the two groups were significantly lower at postoperative 3 days and at the last follow-up when compared with those before operation (all P<0.05), and both values were significantly lower at the last follow-up than those at postoperative 3 days (all P<0.05). There were no significant differences in the VAS or ODI at all time points between the two groups (all P>0.05). The incidence of facet joint violation in the robot group was 1.6%, markedly lower than that in the free-hand group (9.6%) ( P<0.01). The incidences of deviation in guide needle placement, cerebrospinal leak and PJK showed no differences between the two groups (all P>0.05). Conclusion:For type IV CSOVCFs, the robot-assisted long segment screw fixation combined with wedge osteotomy can better reduce intraoperative blood loss, decrease radiation exposure, improve accuracy of pedicle screw placement, and reduce facet joint violation when compared with free-hand long segment screw fixation combined with wedge osteotomy.

Posterior long segment instrumentation combined with transpedicular impaction bone grafting or with bone cement augmentation in the treatment of stage III Kümmell disease: a comparison of efficacies / 中华创伤杂志

Objective:To compare the efficacies of posterior long segment instrumentation combined with transpedicular impaction bone grafting or with bone cement augmentation in treating stage III Kümmell disease.Methods:A retrospective cohort study was conducted to analyze the clinical data of 38 patients with stage III Kümmell disease who were admitted to Zhengzhou Orthopedic Hospital between January 2016 and December 2020. The study included 8 male and 30 female patients, with ages ranging from 59 to 81 years [(68.9±4.9)years]. The vertebral fractures occurred at T 8 in 1 patient, T 11 in 9 patients, T 12 in 10 patients, and L 2 in 10 patients. Seventeen patients underwent posterior long segment instrumentation combined with transpedicular impaction bone grafting (impaction bone grafting group), and 21 patients underwent posterior long segment instrumentation combined with bone cement augmentation (bone cement group). The surgical duration, intraoperative blood loss, and incidences of postoperative complications were compared between the two groups. Additionally, the visual analogue score (VAS), Japanese orthopedic association (JOA) score, and Cobb angle were compared before the operation, at 1 week and 3 months post-operation, and at the final follow-up for both groups. The study also compared bone healing at the last follow-up and postoperative complication rates between the two groups. Results:All the patients were followed up for 24-35 months [(28.7±2.9)months]. The impaction bone grafting group had a surgical duration of (150.7±25.4)minutes and intraoperative blood loss of (285.3±48.6)ml, significantly different from those in the bone cement group [(132.0±21.1)minutes, (251.4±44.8)ml] (all P<0.05). Before the operation, there were no significant differences in the VAS, JOA score, or Cobb angle between the two groups (all P>0.05).The VAS was (3.2±0.8)points, (2.7±0.5)points and (2.2±0.7)points in the impaction bone grafting group and was (2.7±0.6)points, (2.6±0.7)points and (2.4±0.8)points in the bone cement group at 1 week and 3 months post-operation and at the final follow-up, respectively. The VAS in the impaction bone grafting group was significantly higher than that in the bone cement group at 1 week post-operation ( P<0.05); however, no significant differences were found at 3 months post-operation or at the last follow-up (all P>0.05). There was no significant difference in the JOA score between the two groups at 1 week or 3 months post-operation, or at the final follow-up (all P>0.05). The Cobb angle in the impaction bone grafting group was (5.1±1.3)°, (5.9±1.8)° and (6.5±2.5)° at 1 week and 3 months post-operation, and at the final follow-up, significantly lower than that in the bone cement group [(8.4±1.6)°, (12.6±2.1)°, and (14.5±3.3)°] (all P<0.01). All the patients in the impaction bone grafting group achieved bone healing at the last follow-up. One patient in the impaction bone grafting group experienced delayed incision healing, whereas two patients in the bone cement group had poor bone healing. The complication rate was 5.9% (1/17) in the impaction bone grafting group and 9.5% (2/21) in the bone cement group ( P>0.05). Conclusions:Posterior long segment instrumentation combined with transpedicular impaction bone grafting or with bone cement augmentation are both effective in alleviating pain and improving the spinal function for stage III Kümmell disease. The former procedure is associated with longer surgical duration and increased intraoperative blood loss, but it can provide superior correction and maintenance of kyphosis deformity, promoting the healing of the injured vertebrae.

Precision targeted and traditional percutaneous vertebroplasty in treating refracture of injured vertebra after operation for Kümmell disease: a comparison of efficacies / 中华创伤杂志

Objective:To compare the clinical efficacies of precision targeted and traditional percutaneous vertebroplasty (PVP) in the treatment of refracture of injured vertebra after operation for Kümmell disease.Methods:A retrospective cohort study was conducted to analyze the clinical data of 23 Kümmell disease patients suffering from refracture of injured vertebra after PVP in Zhengzhou Orthopedic Hospital from October 2014 to October 2018. The patients included 7 males and 16 females, aged 53-89 years [(69.3±3.5)years]. There were 11 patients of stage I Kümmell disease and 12 patients of stage II Kümmell disease. The vertebral distribution of fracture was T 11 (3 patients), T 12 (9 patients), L 1 (8 patients) and L 2 (3 patients). Eleven patients received traditional PVP treatment (traditional PVP group) and 12 patients received precision targeted PVP treatment (targeted PVP group). The operation time, amount of bone cement injection and filling of bone cement in the fracture space were compared between the two groups. The visual analogue score (VAS) and Oswestry disability index (ODI) were also compared before operation, at 2 days, 1 month, 3 months, 6 months after operation, and at the last follow-up. The rates of bone cement leakage and re-collapse of injured vertebra were observed in the two groups. Results:The patients were followed up for 12-36 months [(24.2±2.6)months]. There were no significant differences in the operation time or amount of bone cement injection between the two groups (all P>0.05). All the fracture spaces in the targeted PVP group were fully filled with bone cement, while 4 patients in the traditional PVP group showed inadequate filling of the fracture area ( P<0.05). The VAS values in the targeted PVP group were (8.9±0.5)points, (1.6±0.2)points, (1.7±0.1)points, (1.8±0.1)points, (1.9±0.3)points, and (1.8±0.4)points before operation, at 2 days, 1 month, 3 months, 6 months after operation and at the last follow-up; and those in the traditional PVP group were (9.1±0.9)points, (1.8±0.4)points, (1.8±0.2)points, (2.0±0.4)points, (2.1±0.2)points, and (2.4±0.3)points, respectively. The VAS values of both groups were significantly decreased at 2 days, 1 month, 3 months, 6 months after operation, and at the last follow-up compared with those before operation (all P<0.05), but there was no significant difference between different time points after operation (all P>0.05). No significant differences were found in the VAS values between the two groups before operation and at 2 days, 1 month, 3 months and 6 months after operation (all P>0.05). However, the VAS value in the targeted PVP group was significantly lower than that in the traditional PVP group at the last follow-up ( P<0.05). The ODI values in the targeted PVP group were 38.5±4.3, 7.2±2.3, 7.3±2.0, 7.2±1.8, 7.3±2.4, and 7.4±2.5 before operation and at 2 days, 1 month, 3 months, 6 months after operation, and at last follow-up; and those in the traditional PVP group were 37.8±4.1, 7.5±2.5, 7.7±1.9, 7.9±2.4, 8.1±2.6, and 9.6±2.4, respectively. The ODI values of both groups were significantly decreased at 2 days, 1 month, 3 months, 6 months after operation and at the last follow-up compared with those before operation (all P<0.05), but there were no significant differences between different time points after operation (all P>0.05). The ODI values were not significantly different between the two groups before operation and at 2 days, 1 month, 3 months, 6 months after operation (all P>0.05), but the ODI value in the targeted PVP group was significantly lower than that in the traditional PVP group at the last follow-up ( P<0.05). There were no significant differences in the rates of bone cement leakage or re-collapse of injured vertebra between the two groups (all P>0.05). Conclusion:Compared with traditional PVP treatment for refracture of injured vertebra after operation for Kümmell disease, targeted PVP can make bone cement injection fully dispersed, greatly reduce pain and promote functional recovery.

Application of the "three-in-one" bone repair strategy in the treatment of osteoporotic fractures / 中华创伤杂志

Osteoporotic fractures secondary to osteoporosis increase very rapidly in incidence, and have become a major cause of disability and mortality in the elderly population. Currently, there have no standard guidelines for perioperative management, surgery and postoperative rehabilitation, causing multiple complications and poor therapeutic outcome. The authors previously proposed bone repair strategies including active anti-osteoporosis, adequate bone grafting and bone healing acceleration, namely "three-in-one" bone repair strategy. The care steps in osteoporotic fracture surgery inluded perioperative management, operative precaution, and postoperative prevention of secondary fractures. With this in mind, the authors further discussed the detailed application of "three-in-one" bone repair strategy including perioperative active anti-osteoporosis treatment, early rehabilitation training, standardized internal fixation selection, standard bone grafting methods and prevention of secondary complications, so as to promote the standardized treatment of osteoporotic fractures and improve the prognosis.

Application of measurement of pedicle parameters before L1 percutaneous vertebroplasty / 中国基层医药

Objective:The included angle of the outermost edge of the pedicle and the front edge of the central line of T12, L1, and L12 in the axial projection was compared before surgery (the incidence angle of the pedicle was set as α). A horizontal line passing through point C was made to cross the inner edge of the pedicle in the axial projection and the intersection point was designated as point D. The distance between point C and point D was compared among T12, L1, and L2. The advantages and feasibility of the measurement of these parameters for guiding puncture and bone cement injection in L1 percutaneous vertebroplasty were investigated.Methods:The clinical data of 91 patients with L1 osteoporotic vertebral compression fracture who underwent percutaneous vertebroplasty in The First People's Hospital of Chu Zhou from January 2018 to November 2021 were retrospectively analyzed. Axial α and CD of the L1 vertebral body and its adjacent vertebral bodies were measured. The amount of bone cement injected during the surgery, bone cement leakage rate, and pre- and post-surgery Visual Analogue Scale score were determined.Results:The α and CD of L1 in the axial projection were (20.43 ± 1.61)° and (5.37 ± 1.08) mm, respectively. Bone cement leakage rates of unilateral and bilateral approaches of L1 vertebral body were 35% and 12%, respectively, and there was a significant difference between the two approaches ( χ2 = 6.08, P < 0.05). There was no significant difference in the amount of bone cement injected during the surgery between unilateral and bilateral approaches of L1 ( P > 0.05). There was no significant difference in pre- and post-surgery Visual Analogue Scale scores between unilateral and bilateral approaches of L1 ( P > 0.05). Conclusion:The α and CD of L1 in the axial projection are smaller than those of other adjacent vertebral bodies, which is of great significance for selecting a puncture path and reducing bone cement leakage.

Efficacy of modified prescription of Bushen Huoxue Decoction combined with Zhengguling Capsule after surgical treatment of osteoporotic fractures / 中国基层医药

Objective:To investigate the clinical application value of modified prescription of Bushen Huoxue Decoction combined with Zhengguling Capsule after surgical treatment of osteoporotic fracture. Methods:Eighty patients undergoing surgical treatment of osteoporotic fractures in Jiamusi Orthopedic Hospital from January 2019 to January 2021 were included in this study. They were randomly divided into a control group ( n = 40, receiving routine western medicine treatment) and a study group ( n = 40, receiving adjuvant treatment with modified prescription of Bushen Huoxue Decoction combined with Zhengguling Capsule based on routine western medicine treatment). All patients were treated for 6 consecutive months. The Fugl-Meyer Assessment scale score of motor function, traditional Chinese medicine symptom score, modified Barthel Index (MBI) score, bone mineral density T value at different treatment time points, clinical efficacy, and incidence of adverse reactions were compared between the two groups before and after treatment. Results:At 1, 2, 3 and 6 months of treatment, the T value of bone mineral density in the study group was significantly higher than that in the control group (all P < 0.001). At the end of treatment, the modified Barthel Index and the Fugl-Meyer Assessment scale score in the study group were (78.05 ± 4.26) points and (88.53 ± 2.35) points, which were significantly greater than (70.02 ± 6.58) points and (82.75 ± 2.44) points in the control group ( t = 6.49, 13.92, both P < 0.05). At the end of treatment, the symptom score in the study group was significantly lower than that in the control group ( P < 0.001). Total response rate in the study group was significantly higher than that in the control group [97.5% (39/40) vs. 80.0% (32/40), χ2 = 6.14, P < 0.05]. There was no significant difference in incidence of adverse reactions between the two groups ( P > 0.05). Conclusion:Modified prescription of Bushen Huoxue Decoction combined with Zhengguling Capsule can effectively improve motor ability and increase bone mineral density T value in patients after surgical treatment for osteoporotic fracture.

Curative effects of traditional Chinese medicine paste combined with Baduanjin in treatment of osteoporotic vertebral compression fracture after PVP / 药学实践杂志

Objective To study the curative effects of traditional Chinese medicine paste combined with Baduanjin in treatment of osteoporotic vertebral compression fracture (OVCF) after percutaneous vertebroplasty (PVP). Methods 120 OVCF patients treated with PVP in our hospital from January 2016 to September 2017 were divided into the observation group (60 cases) and the control group (60 cases) according to the random number table method. The control group was given calcium carbonate D3 chewable tablets orally with routine guidance. In addition to the same treatment as the control group, the observation group received the traditional Chinese medicine paste orally with Baduanjin exercise. Both groups were treated for 6 months and followed-up for 3 years. The curative effects in the two groups after 6 months treatment and the low back pain after 1, 3 and 6 months of treatment were recorded. The changes of bone mineral density (BMD), kyphosis angle (Cobb angle), anterior wall height of vertebral body (AVBH) and level of bone metabolism indexes in the two groups were compared before and after treatment for 6 months. The follow-up times and the incidences of push-back fracture after PVP during follow-up were recorded. Results After 6 months of treatment, the clinical cure rate of the observation group was 73.33%, which was higher than 53.33% of the control group(P<0.05). Compared with pretreatment, the scores of visual analogue scale (VAS) in the two groups gradually decreased after 3 and 6 months of treatment, and the observation group had a lower scores than the control group (P<0.05). After 6 months treatment, BMD and AVBH of lumbar vertebrae and femoral neck in both groups increased, and the observation group was higher than that in the control group. The Cobb angle and serum levels of Type I procollagen degradation products (β-Cross I), the n-terminal middle osteocalcin (N-MID Ost) and parathyroid hormone (PTH) decreased in both groups, and the observation group was lower than those in the control group (P<0.05). There was no significant difference in fracture incidence after PVP in the year 1, year 1 to 3 follow up between the two groups (P>0.05). During the 3 years follow-up, the incidence of push-body fracture after PVP in the observation group was 3.33%, which was lower than that in the control group 20.00%( P<0.05).

The curative effects were remarkable.

Research progress in prevention and disease management of osteoporotic fractures / 上海预防医学

Osteoporotic fracture is the most major complication of osteoporosis. It is a significant global public health problem which continues to bring serious family and social burden. In order to improve the prevention and treatment of osteoporotic fractures， many countries have carried out new ways of fracture prevention and management， and achieved some results. Prevention mainly aims at those at high risk of fracture， and includes new health education on fracture and the promotion of fall prevention measures. For management， the "Fracture liaison services" mode is mainly applied to the fracture patients， with refined patient management to deal with the fractures that have occurred. This article summarizes the global prevalence of osteoporotic fractures， risk factors， and the current research progress in fracture prevention and management in China and the West.

Effects of percutaneous kyphoplasty assisted by Huoxue Yigu Decoction on the bone healing and postoperative recovery of lumbar function in elderly patients with osteoporotic vertebral compression fractures / 国际中医中药杂志

Objective:To explore the effects of percutaneous kyphoplasty (PKP) assisted by Huoxue Yigu Decoction on bone healing and postoperative recovery of lumbar function in elderly patients with osteoporotic vertebral compression fractures (OVCF).Methods:Randomized controlled trial. A total of 79 elderly patients with OVCF admitted to Zhongshan Hospital Affiliated to Fudan University were enrolled as the research objects between October 2017 and February 2021. According to random number table method, they were divided into observation group (40 cases) and control group (39 cases). The patients in the control group were treated with PKP, then they were given off-bed activities with thoracolumbar braces at 2 d after surgery and the braces were removed at 1 month after surgery, while the observation group was treated with Huoxue Yigu Decoction for 7 d on the basis of control group treatment. Before surgery and at 3 months after surgery, TCM syndromes were scored. The lumbar function was evaluated by Japanese Orthopedic Association (JOA). The pain degree was evaluated by visual analogue scale (VAS) at 7 d and 1 month after surgery. Before surgery and at 7 d after surgery, levels of serum osteocalcin and bone alkaline phosphatase (BALP) were detected by radioimmunoassay. The levels of serum IL-1, IL-6 and TNF-α were detected by ELISA. The erythrocyte aggregation index, whole blood viscosity and plasma viscosity were detected by full-automatic blood rheometer. Before and at 3 months after surgery, loss rate of anterior margin vertebral height and sagittal kyphosis Cobb angle were detected by X-ray films. The bone mineral density (BMD) of femoral shaft was measured by dual-energy bone densitometer. The occurrence of postoperative complications was recorded.Results:There was no significant difference in total response rate between the observation group and control group [97.5% (39/40) vs. 92.3% (36/39); χ2=0.29, P=0.590]. At 3 months after surgery, scores of TCM syndromes in observation group were significantly lower than that of the control group ( t=5.63, P<0.01), and JOA score was significantly higher than that of the control group ( t=3.93, P<0.01). At 1 month after surgery, VAS score in observation group was significantly lower than that of the control group ( t=6.90, P<0.01). At 7d after surgery, levels of osteocalcin [(4.19±0.65) μg/L vs. (3.21±0.61) μg/L, t=6.91] and BMD [(0.86±0.17) g/cm 2vs. (0.71±0.15) g/cm 2, t=4.16] in observation group were significantly higher than those in the control group ( P<0.01), while BALP [(20.07±3.19) U/L vs. (22.16±3.52) U/L, t=2.77] was significantly lower than that of the observation group ( P<0.01). At 3 months after surgery, loss rate of anterior margin vertebral height and sagittal kyphosis Cobb angle in observation group were significantly lower than those in the control group ( t=2.59, 2.81, P<0.01). At 7d after surgery, erythrocyte aggregation index, whole blood viscosity and plasma viscosity in observation group were significantly lower than those in the control group ( t=2.92, 6.33, 4.64, P<0.01), and levels of serum IL-1, IL-6 and TNF-α were significantly lower than those in the control group ( t=2.33, 2.47, 3.45, P<0.01). There was no significant difference in incidence of postoperative complications between observation group and control group [2.50% (1/40) vs. 10.26% (4/39); χ2=2.00, P>0.05]. Conclusion:Huoxue Yigu Decoction can alleviate postoperative pain, promote bone healing and recovery of lumbar function, improve blood circulation and reduce inflammation level in elderly OVCF patients undergoing PKP.

Application of different puncture techniques to inject bone cement in osteoporotic vertebral compression fractures / 中国骨伤

OBJECTIVE@#To study the application of different puncture techniques to inject bone cement in osteoporotic vertebral compression fractures (OVCFs).@*METHODS@#The clinical data of 282 patients with OVCFs treated from January 2017 to December 2019 were collected for a retrospective study. According to the surgical plan the patients were divided into group A and B, with 141 cases in each group. In group A, extreme lateral puncture was used to inject bone cement through unilateral puncture and bilateral puncture. In group B, bone cement was injected through unilateral pedicle puncture through pedicle approach. The operation status(operation time, radiation exposure time, bone cement injection volume, hospital stay) and complications were observed between two groups. Before operation and 6, 12 months after operation, the pain mediators such as serotonin 5-hydroxytryptamine (5-HT), prostaglandin E2(PGE2), substance P(SP) were compared, bone mineral density, anatomical parameters of the injured vertebrae (height of the anterior edge of the vertebral body, height of the posterior edge of the vertebral body, Cobb angle), visual analogue scale (VAS) and Oswestry disability index (ODI) were evaluated between two groups.@*RESULTS@#There were no significant difference in operation time, radiation exposure time, hospital stay between two groups (P>0.05). The amount of bone cement injected in group A was greater than that in group B (P<0.05). The serum 5-HT, SP and PGE2 levels of group A were lower than those of group B at 12 months after operation (P<0.05). The height of anterior edge and height of the posterior edge of vertebral body in group A were greater than those of group B at 12 months after operation, Cobb angle of group A was smaller than that of group B, VAS and ODI were lower than those of group B(P<0.05). There was no significant difference in bone mineral density between two groups at 6 and 12 months postoperatively(P<0.05). There was no significant difference between two groups in postoperative complications (P>0.05).@*CONCLUSION@#Compared with unilateral puncture of the pedicle approach, unilateral puncture and bilateral cement injection technique is more conducive to the recovery of the injured vertebral anatomy and function, and do not prolong operation time, radiation exposure time, hospital stay, nor do increase the risk of nerve damage and bone cement leakage, and postoperative bone metabolism and bone mineral density are improved well, which is a safe and reliable surgical method for the treatment of OVCFs.

Iron accumulation and its impact on osteoporotic fractures in postmenopausal women / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Postmenopausal osteoporosis is a kind of degenerative disease, also described as "invisible killer." Estrogen is generally considered as the key hormone for women to maintain bone mineral content during their lives. Iron accumulation refers to a state of human serum ferritin that is higher than the normal value but less than 1000 μg/L. It has been found that iron accumulation and osteoporosis could occur simultaneously with the decrease in estrogen level after menopause. In recent years, many studies indicated that iron accumulation plays a vital role in postmenopausal osteoporosis, and a significant correlation has been found between iron accumulation and fragility fractures. In this review, we summarize and analyze the relevant literature including randomized controlled trials, systematic reviews, and meta-analyses between January 1996 and July 2022. We investigate the mechanism of the effect of iron accumulation on bone metabolism and discuss the relationship of iron accumulation, osteoporosis, and postmenopausal fragility fractures, as well as the main clinical treatment strategies. We conclude that it is necessary to pay attention to the phenomenon of iron accumulation in postmenopausal women with osteoporosis and explore the in-depth mechanism of abnormal bone metabolism caused by iron accumulation, in order to facilitate the discovery of effective therapeutic targets for postmenopausal osteoporosis.

Effect of injury degree of osteoporotic vertebral compression fracture on bone cement cortical leakage after percutaneous kyphoplasty / 中国修复重建外科杂志

OBJECTIVE@#To analyze the correlation between bone cement cortical leakage and injury degree of osteoporotic vertebral compression fracture (OVCF) after percutaneous kyphoplasty (PKP), and to provide guidance for reducing clinical complications.@*METHODS@#A clinical data of 125 patients with OVCF who received PKP between November 2019 and December 2021 and met the selection criteria was selected and analyzed. There were 20 males and 105 females. The median age was 72 years (range, 55-96 years). There were 108 single-segment fractures, 16 two-segment fractures, and 1 three-segment fracture. The disease duration ranged from 1 to 20 days (mean, 7.2 days). The amount of bone cement injected during operation was 2.5-8.0 mL, with an average of 6.04 mL. Based on the preoperative CT images, the standard S/H ratio of the injured vertebra was measured (S: the standard maximum rectangular area of the cross-section of the injured vertebral body, H: the standard minimum height of the sagittal position of the injured vertebral body). Based on postoperative X-ray films and CT images, the occurrence of bone cement leakage after operation and the cortical rupture at the cortical leakage site before operation were recorded. The correlation between the standard S/H ratio of the injured vertebra and the number of cortical leakage was analyzed.@*RESULTS@#Vascular leakage occurred in 67 patients at 123 sites of injured vertebrae, and cortical leakage in 97 patients at 299 sites. Preoperative CT image analysis showed that there were 287 sites (95.99%, 287/299) of cortical leakage had cortical rupture before operation. Thirteen patients were excluded because of vertebral compression of adjacent vertebrae. The standard S/H ratio of 112 injured vertebrae was 1.12-3.17 (mean, 1.67), of which 87 cases (268 sites) had cortical leakage. The Spearman correlation analysis showed a positive correlation between the number of cortical leakage of injured vertebra and the standard S/H ratio of injured vertebra ( r=0.493, P<0.001).@*CONCLUSION@#The incidence of cortical leakage of bone cement after PKP in OVCF patients is high, and cortical rupture is the basis of cortical leakage. The more severe the vertebral injury, the greater the probability of cortical leakage.

Agreement on mri diagnosis in compressive malignant vertebral fractures / Concordância no diagnóstico por rm em fraturas vertebrais malignas compressivas

ABSTRACT Objective: Verify interobserver and intraobserver agreement of malignant compressive vertebral fractures (MCVF) diagnosis using magnetic resonance imaging (MRI). Methods: We retrospectively included a lumbar spine MRI of 63 patients with non-traumatic compressive vertebral fracture diagnoses. Each lumbar vertebra was classified as: without fracture, with fracture of benign characteristics, or with fracture of malignant characteristics. Two medical residents in radiology, one musculoskeletal radiologist fellow, one musculoskeletal radiologist, and two spine surgeons evaluated MRI exams, independently and blindly. Each observer performed two readings, with a 15-day interval between evaluations. A simple Kappa coefficient was used to calculate the intra and interobserver agreement. The reference standard classification was based on bone biopsy or clinical, and imaging follow-up of at least two years, for diagnostic performance analysis. Diagnostic performance was assessed by calculating sensitivity, specificity, accuracy, and positive and negative predictive values with a 95% confidence interval (CI). Results: We observed substantial to perfect intraobserver agreement (kappa: 0.80 to 1.00) and substantial interobserver agreement (kappa 0.64 to 0.77). In general, the sensitivity for the detection of MCVF was moderate, except for the second-year radiology resident that achieved a lower sensitivity. The specificity, accuracy, and negative predictive value were high for all observers. Conclusion: MCVF diagnosis using MRI showed substantial interobserver agreement. The second-year medical resident achieved lower sensitivity but high specificity for MCVF. Regarding the seniors, there was no statistical significance between spine surgeons and the musculoskeletal radiologist. Level of Evidence III; Diagnostic.

RESUMO Objetivo: Verificar a concordância interobservador e intraobservador no diagnóstico de fraturas vertebrais compressivas malignas (MCVF) por meio de ressonância magnética (MRI). Métodos: Incluiu-se retrospectivamente a ressonância magnética da coluna lombar de 63 pacientes com diagnóstico de fratura vertebral compressiva não traumática. Cada vértebra lombar foi classificada da seguinte forma: sem fratura, com fratura de características benignas ou com fratura de características malignas. Dois médicos residentes em radiologia, um pesquisador radiologista musculoesquelético, um radiologista musculoesquelético e dois cirurgiões da coluna vertebral avaliaram os exames de ressonância magnética, independentemente e cegamente. Cada observador realizou duas leituras, com um intervalo de 15 dias entre as avaliações. O coeficiente Kappa simples foi utilizado para calcular o acordo intra e interobservador. A classificação padrão de referência foi baseada em biópsia óssea ou clínica, e acompanhamento por imagem de pelo menos dois anos, para análise de desempenho diagnóstico. O desempenho diagnóstico foi avaliado através do cálculo de sensibilidade, especificidade, precisão, valores preditivos positivos e negativos com um intervalo de confiança de 95% (IC). Resultados: Foi observada concordância substancial a perfeita intraobservador (kappa: 0,80 a 1,00) e concordância substancial interobservador (kappa 0,64 a 0,77). Em geral, a sensibilidade para a detecção de MCVF foi moderada, exceto para o segundo ano de residência radiológica que alcançou uma sensibilidade menor. A especificidade, precisão e valor preditivo negativo foram altos para todos os observadores. Conclusão: O diagnóstico de MCVF por ressonância magnética mostrou uma concordância substancial entre observadores. O residente médico do segundo ano alcançou uma sensibilidade menor, mas alta especificidade para MCVF. Com relação aos veteranos, não houve significância estatística entre os cirurgiões da coluna vertebral e o radiologista músculo-esquelético. Nível de Evidencia III; Diagnóstico.

Do older patients "warn" that they will suffer a new fracture? / O paciente idoso "avisa" que vai sofrer uma nova fratura?

ABSTRACT Objective: To evaluate whether patients older than 60 years admitted for fracture treatment had a history of previous fracture, a diagnosis of osteoporosis, or were under treatment for bone fragility. Methods: Retrospective study including 100 patients older than 60 years with fracture. Fracture location, bone densitometry within the past two years, previous diagnosis and osteoporosis treatment, and previous fracture within the past five years were assessed. Using Fisher's test, it was evaluated whether there was an association between previous fracture and osteoporosis treatment. Results: The most prevalent fracture was in the proximal femur (48%). Of the patients, 18% had fracture in the last five years, with 22% of them diagnosed with osteoporosis, and 22% under treatment. Previous fracture in the last five years was not associated with having a diagnosis of osteoporosis, having had bone densitometry, or being under treatment for osteoporosis. Conclusion: Among patients with previous fracture, only 22% were aware of their diagnosis of osteoporosis, and less than 25% of them were under bone fragility treatment. Previous fracture in the past five years had no association with having a diagnosis of osteoporosis, having had bone densitometry, or being on osteoporosis treatment. Level of Evidence III, Retrospective Study.

RESUMO Objetivo: Avaliar se os pacientes com mais de 60 anos internados para tratamento de fraturas têm história de fratura prévia, diagnóstico de osteoporose ou se estão em tratamento para fragilidade óssea. Métodos: Estudo retrospectivo que inclui 100 pacientes maiores de 60 anos com fratura. Avaliamos a localização da fratura, a densitometria óssea nos últimos dois anos, o diagnóstico e os tratamentos anteriores de osteoporose, assim como a presença de fratura prévia nos últimos cinco anos. Através de testes de Fisher avaliamos se houve associação entre fratura prévia e tratamento de osteoporose. Resultados: A fratura mais prevalente foi na extremidade proximal do fêmur (48%). Do total de pacientes, 18% tiveram fratura nos últimos cinco anos, sendo que 22% deles tinham diagnóstico de osteoporose e 22% estavam em tratamento. Fratura prévia nos últimos cinco anos não teve associação com diagnóstico de osteoporose, realização de densitometria óssea ou tratamento para osteoporose. Conclusão: Entre os pacientes com fratura prévia, apenas 22% estavam cientes do diagnóstico de osteoporose, e menos de 25% deles estavam em tratamento para fragilidade óssea. Não houve associação de fratura prévia nos últimos cinco anos com diagnóstico de osteoporose, realização de densitometria óssea ou tratamento para osteoporose. Nível de Evidência III, Estudo Retrospectivo.

Is Follow-up Co-Morbidity Assessment via Laboratory Investigations in Older High Energy Trauma Patients Justified? - A Prospective-Retrospective Study

@#Introduction: The objective of the current study was to test our hypothesis that older patients sustaining high energy trauma need to be evaluated for their comorbidities similar to geriatric patients sustaining low energy trauma. Materials and methods: This study was a retrospectiveprospective analysis of 173 patients of more than 50 years of age enrolled between November 2017 and December 2018. Herewith, we have compared retrospectively collected laboratory investigations of 124 fragility fracture patients with prospectively collected laboratory investigations of 49 patients with high energy trauma. The laboratory investigations, including the liver function tests, renal function tests, indices of calcium metabolism, serum electrolytes, complete blood counts, and bone mineral density (BMD) scores. Results: Both groups were similar to each other as far as baseline demographic characteristics were concerned. The proportion of female patients and patients with nonosteoporotic range BMD (T-score >-2.5) was significantly higher in the high-energy fracture group (P value <0.05). Hypoalbuminemia (<3.4gm/dl) 17.3%, abnormalities sodium (<135mmol/L or >148mmol/L) 23.2%, Anaemia (<10g/dl) 12.7%, Hypercalcemia (>10.4mg/dl) 16.3%, Vitamin D deficiency (<20ng/ml) 17.3% are the common laboratory abnormality found in study population. No statistically significant difference was found among the two groups in terms of laboratory investigation abnormalities. Conclusion: The laboratory investigation abnormality in an older patient with a clinical fracture is independent of the mechanism of injury. The results of the current study emphasise the need for a comprehensive laboratory workup in older patients with either high- energy fractures or fragility fractures.
