Supra-inguinal fascia iliaca block in older-old patients for hip fractures: a retrospective study

Abstract Background: Pain management in hip fracture patients is of great importance for reducing postoperative morbidity and mortality. Multimodal techniques, including peripheral nerve blocks, are preferred for postoperative analgesia. Older-old hip fracture patients with high ASA scores are highly sensitive to the side effects of NSAIDs and opioids. Our aim was to investigate the effectiveness of the recently popularized Supra-Inguinal Fascia Iliaca Block (SIFIB) in this population. Methods: Forty-one ASA III-IV patients who underwent SIFIB + PCA (G-SIFIB) or PCA alone (Group Control: GC) after general anesthesia were evaluated retrospectively. In addition to 24-hour opioid consumption, Visual Analog Scale (VAS) scores, opioid-related side effects, block-related complications, and length of hospital stay were compared. Results: Twenty-two patients in G-SIFIB and 19 patients in GC were evaluated. The postoperative 24-hour opioid consumption was lower in G-SIFIB than in GC (p < 0.001). There was a statistically significant reduction in VAS scores at the postoperative 1st, 3rd, and 6th hours at rest (p < 0.001) and during movement (p < 0.001 for the 1st and 3rd hours, and p = 0.02 for the 6th hour) in G-SIFIB compared to GC. There was no difference in pain scores at the 12th and 24th hours postoperatively. While there was no difference between the groups in terms of other side effects, respiratory depression was significantly higher in GC than in G-SIFIB (p = 0.01). Conclusion: The SIFIB technique has a significant opioid-sparing effect and thus reduces opioid-related side effects in the first 24 hours after hip fracture surgery in older-old patients.

Desde el análisis biomecánico óseo de koch hasta el manejo contemporáneo de la fractura del fémur proximal / From koch's bone biomechanical analysis to contemporary proximal femur fracture management

Este artículo representa una revisión actual y completa de las fuerzas biomecánicas en el fémur proximal, tal como Koch presentó preliminarmente en su trabajo sobre la arquitectura ósea del fémur proximal. Su trabajo reflejó en la complejidad de las fracturas de fémur proximal y el manejo de las fracturas subtrocantéricas en paralelo con su clasificación y con la evolución de implantes. Existen múltiples formas de clasificar las fracturas subtrocantéricas; sin embargo, no existe un sistema de clasificación que se utilice para guiar el manejo quirúrgico. El tratamiento de las fracturas subtrocantéricas es la fijación quirúrgica, que implica el enclavado endomedular y placas de osteosíntesis. El tratamiento estándar es el enclavado endomedular con opciones de enclavado anterógrado y retrógrado. Aunque el enclavado anterógrado presenta una ventaja debido a las fuerzas deformantes, el enclavado retrógrado de las fracturas de fémur proximal ofrece menos tiempo quirúrgico y pérdida de sangre. Se han informado resultados similares entre los dos métodos. La toma de decisiones cuando se contempla el enclavado anterógrado versus retrógrado para las fracturas de fémur se basa principalmente en la constitución corporal y las lesiones asociadas, y no en la distancia de la fractura del fémur proximal a la región trocantérica

This article presents a current and comprehensive review of the biomechanical forces on the proximal femur, as preliminarily presented by Koch's cornerstone work on the bone architecture of the proximal femur. His work reflected on the complexity of proximal femur fractures and subtrochanteric fracture management in parallel with implant evolution and classification. Multiple ways of classifying subtrochanteric fractures exist, however, there is not one classification system that is used to guide operative management. The management of subtrochanteric fractures is surgical fixation which involves intramedullary nailing and plating (e.g., fixed angle and locking). The gold standard management is intramedullary nailing with antegrade and retrograde nail options. Though antegrade nailing presents an advantage due to the deforming forces, retrograde nailing of proximal femur fractures offers less operative time and blood loss. Similar outcomes have been reported between the two methods. Decision making when contemplating antegrade versus retrograde nailing for femur fractures is mostly driven by body habitus and associated injuries, and not by fracture distance of the proximal femur to the trochanteric region

Pipkin Type-II Femoral Head Fracture: A Biomechanical Evaluation by the Finite-Element Method / Fratura da cabeça femoral de tipo II de Pipkin: Avaliação biomecánica pelo método de elementos finitos

Abstract Objective To evaluate the biomechanical capacity of two forms of fixation for Pipkin type-II fractures, describing the vertical fracture deviation, the maximum and minimum principal stresses, and the Von Mises equivalent stress in the syntheses used. Materials and Methods Two internal fasteners were developed to treat Pipkin type-II fractures through finite elements: a 3.5-mm cortical screw and a Herbert screw. Under the same conditions, the vertical fracture deviation, the maximum and minimum principal stresses, and the Von Mises equivalent stress in the syntheses used were evaluated. Results The vertical displacements evaluated were of 1.5mm and 0.5mm. The maximum principal stress values obtained in the upper region of the femoral neck were of 9.7 KPa and 1.3 Kpa, and the minimum principal stress values obtained in the lower region of the femoral neck were of-8.7 KPa and -9.3 KPa. Finally, the peak values for Von Mises stress were of 7.2 GPa and 2.0 GPa for the fixation models with the use of the 3.5-mm cortical screw and the Herbert screw respectively. Conclusion The fixation system with the Herbert screw generated the best results in terms of reduction of vertical displacement, distribution of the maximum principal stress, and the peak Von Mises equivalent stress, demonstrating mechanical superiority compared to that of the 3.5-mm cortical screw in the treatment of Pipkin type-II fractures.

Outcome of buttress plate-nail construct used for reconstruction of broken lateral wall in intertrochanteric fractures / 中华创伤杂志(英文版)

PURPOSE@#Intramedullary implants are well accepted fixation of all types of intertrochanteric (IT) fractures, both stable and unstable types. Intramedullary nails have an ability to effectively support the posteromedial part, but fail to buttress the broken lateral wall requiring lateral augmentation. The aim of this study was to evaluate the outcome of proximal femoral nail augmented with trochanteric buttress plate for broken lateral wall with IT fractures, which was fixed to the femur through hip screw and anti-rotation screw nail.@*METHODS@#Of 30 patients, 20 had Jensen-Evan type III and 10 had type V fractures. Patients with IT fracture of broken lateral wall and aged more than 18 years, in whom satisfactory reduction was achieved by closed methods, were included in the study. Patients with pathologic or open fractures, polytrauma, prior hip surgery, non-ambulatory prior to surgery, and those who refused to participate were excluded. The operative time, blood loss, radiation exposure, quality of reduction, functional outcome, and union time were evaluated. All data were coded and recorded in Microsoft Excel spread sheet program. SPSS 20.0 was used for data analysis and normality of the continuous data was checked using Kolmogorv Smirnov test.@*RESULTS@#The mean age of patients in the study was 60.3 years. The mean duration of surgery (min), mean intra-operative blood loss (mL) and mean number of exposures were 91.86 ± 12.8 (range 70 - 122), 144.8 ± 3.6 (range 116 - 208), and 56.6 (range 38 - 112), respectively. The mean union time was 11.6 weeks and the mean Harris hip score was 94.1.@*CONCLUSION@#Lateral trochanteric wall in IT fractures is significantly important, and needs to be reconstructed adequately. Nail-plate construct of trochanteric buttress plate fixed with hip screw and anti-rotation screw of proximal femoral nail can be successfully used to augment, fix or buttress the lateral trochanteric wall giving excellent to good results of early union and reduction.

Primary repair for concurrent bilateral intertrochanteric fracture and femoral head necrosis with prolonged shank biologic total hip replacement: A case report and surgical techniques / 中华创伤杂志(英文版)

For the treatment of an intertrochanteric fracture combined with femoral head necrosis in middle-age patients, it has been controversial whether to perform fracture reduction and fixation first then total hip replacement, or direct total hip replacement. We present a rare case of 53-year-old male patient suffered from bilateral intertrochanteric fracture caused by a road traffic injury. The patient had a history of femoral head necrosis for eight years, and the Harris score was 30. We performed total hip replacement with prolonged biologic shank prostheses for primary repair. One year after the surgery, nearly full range of motion was achieved without instability (active flexion angle of 110°, extension angle of 20°, adduction angle of 40°, abduction angle of 40°, internal rotation angle of 25°, and external rotation angle of 40°). The Harris score was 85. For the middle-aged patient with unstable intertrochanteric fractures and osteonecrosis of the femoral head, we can choose primary repair for concurrent bilateral intertrochanteric fracture and femoral head necrosis with prolonged shank biologic total hip replacement.

Perioperative mortality and morbidity of hip fractures among COVID-19 infected and non-infected patients: A systematic review and meta-analysis / 中华创伤杂志(英文版)

PURPOSE@#Hip fractures among elderly patients are surgical emergencies. During COVID-19 pandemic time, many such patients could not be operated at early time because of the limitation of the medical resources, the risk of infection and redirection of medical attention to a severe infective health problem.@*METHODS@#A search of electronic databases (PubMed, Medline, CINAHL, EMBASE and the Cochrane Central Register of Controlled Trials) with the keywords "COVID", "COVID-19″, "SARS-COV-2", "Corona", "pandemic", "hip fracture", "trochanteric fracture" and "neck femur fracture" revealed 64 studies evaluating treatment of hip fracture in elderly patients during COVID-19 pandemic time. The 30-day mortality rate, inpatient mortality rate, critical care/special care need, readmission rate and complications rate in both groups were evaluated. Data were analyzed using Review Manager (RevMan) V.5.3.@*RESULTS@#After screening, 7 studies were identified that described the mortality and morbidity in hip fractures in both COVID-19 infected (COVID-19 +) and non-infected (COVID-19 -) patients. There were significantly increased risks of 30-day mortality (32.23% COVID-19 + death vs. 8.85% COVID-19 - death) and inpatient mortality (29.33% vs. 2.62%) among COVID-19 + patients with odds ratio (OR) of 4.84 (95% CI: 3.13 - 7.47, p < 0.001) and 15.12 (95% CI: 6.12 - 37.37, p < 0.001), respectively. The COVID-19 + patients needed more critical care admission (OR = 5.08, 95% CI: 1.49 - 17.30, p < 0.009) and they remain admitted for a longer time in hospital (mean difference = 3.6, 95% CI: 1.74 - 5.45, p < 0.001); but there was no difference in readmission rate between these 2 groups. The risks of overall complications (OR = 17.22), development of pneumonia (OR = 22.25), and acute respiratory distress syndrome/acute respiratory failure (OR = 32.96) were significantly high among COVID-19 + patients compared to COVID-19 - patients.@*CONCLUSIONS@#There are increased risks of the 30-day mortality, inpatient mortality and critical care admission among hip fracture patients who are COVID-19 +. The chances of developing pneumonia and acute respiratory failure are more in COVID-19 + patients than in COVID-19 ‒ patients.

A medium term analysis on of therapeutic effects of bio-lengthend stem hemiarthroplasty in the treatment of unstable osteoporotic intertrochanteric fractures in elderly patients / 中国骨伤

OBJECTIVE@#To retrospectively study medium term follow up outcomes effects of effect of bio-lengthend stem hemiarthroplasty in the treatment of unstable osteoporotic intertrochanteric fractures in elderly patients.@*METHODS@#Total of 32 elderly patients with the osteoporotic intertrochanteric fractures were treated with bio-lengthend stem hemiarthroplasty from Jan. 2016 to Jan. 2019 including 14 males and 22 females, aged from 85 to 95 years old with an average of (89.5±4.5) years old. According to classification of Evans, there were 12 cases with type Ⅲ, 11 with type Ⅳ and 9 with type Ⅳ. The time from injury to operation ranged from 0.5 to 9 days with an average of (4.5±3.9) days. The operation time, blood loss and postoperative complications were analyzed. Functional outcome was assessed by Parker Palmer mobility score(PPMS) and Harris hip score.@*RESULTS@#Four patients died within one year after operation, and the mortality was 12.5%. The follow up time for the rest 28 patients ranged from 24 to 60 months with an average of (28.5±4.5) months. The mean operative time was (54.2±22.5) min;the mean blood loss (hidden blood loss+obvious blood loss) was (450±140) ml;the first weight bearing was (3.35±1.35) days. No perioperative death occurred. PPMS were(6.63±1.25), (6.94±1.18), (7.11±0.83), (7.32±1.11) and Harris scores were(67.85±6.19), (71.42±5.57), (73.41±5.62), (77.32±5.24) respectively at 1, 3, 6 months and the final follow-up after operation. There were no significant difference in PPMS and Harris score at 1, 3, 6 months after operation and the final follow-up(P>0.05). There were no complications such as joint dislocation and prosthesis loosening occure at the final follow-up.@*CONCLUSION@#On the premise of strictly mastering the case selection criteria, the bio-lengthend stem hemiarthroplasty in the treatment of unstable osteoporotic intertrochanteric fractures in elderly patients has a satisfied medium term follow-up outcomes. It can restore hip function in the early stage and improve the quality of life of patients.

Biomechanical effects of three internal fixation modes on femoral subtrochanteric spiral fractures in osteoporotic patients by finite element analysis / 中国修复重建外科杂志

OBJECTIVE@#The biomechanical characteristics of three internal fixation modes for femoral subtrochanteric spiral fracture in osteoporotic patients were compared and analyzed by finite element technology, so as to provide the basis for the optimization of fixation methods for femoral subtrochanteric spiral fracture.@*METHODS@#Ten female patients with osteoporosis and femoral subtrochanteric spiral fractures caused by trauma, aged 65-75 years old, with a height of 160-170 cm and a body weight mass of 60-70 kg, were selected as the study subjects. The femur was scanned by spiral CT and a three-dimensional model of the femur was established by digital technology. The computer aided design models of proximal intramedullary nail (PFN), proximal femoral locking plate (PFLP), and the combination of the two (PFLP+PFN) were constructed under the condition of subtrochanteric fracture. Then the same load of 500 N was applied to the femoral head, and the stress distribution of the internal fixators, the stress distribution of the femur, and the displacement of femur after fracture fixation were compared and analyzed under the three finite element internal fixation modes, so as to evaluate the fixation effect.@*RESULTS@#In the PFLP fixation mode, the stress of the plate was mainly concentrated in the main screw channel, the stresses of the different part of the plate were not equal, and gradually decreased from the head to the tail. In the PFN fixation mode, the stress was concentrated in the upper part of the lateral middle segment. In the PFLP+PFN fixation mode, the maximum stress appeared between the first and the second screws in the lower segment, and the maximum stress appeared in the lateral part of the middle segment of the PFN. The maximum stress of PFLP+PFN fixation mode was significantly higher than that of PFLP fixation mode, but significantly lower than that of PFN fixation mode ( P<0.05). In PFLP and PFN fixation modes, the maximum stress of femur appeared in the medial and lateral cortical bone of the middle femur and the lower side of the lowest screw. In PFLP+PFN fixation mode, the stress of femur concentrated in the medial and lateral of the middle femur. There was no significant difference in the maximum stress of femur among the three finite element fixation modes ( P>0.05). The maximum displacement occurred at the femoral head after three finite element fixation modes were used to fix subtrochanteric femoral fractures. The maximum displacement of femur in PFLP fixation mode was the largest, followed by PFN, and PFLP+PFN was the minimum, with significant differences ( P<0.05).@*CONCLUSION@#Under static loading conditions, the PFLP+PFN fixation mode produces the smallest maximum displacement when compared with the single PFN and PFLP fixation modes, but its maximum plate stress is greater than the single PFN and PFLP fixation mode, suggesting that the combination mode has higher stability, but the plate load is greater, and the possibility of fixation failure is higher.

Effectiveness validation of a novel comprehensive classification for intertrochanteric fractures / 中国修复重建外科杂志

OBJECTIVE@#To validate the effectiveness of a novel comprehensive classification for intertrochanteric fracture (ITF).@*METHODS@#The study included 616 patients with ITF, including 279 males (45.29%) and 337 females (54.71%); the age ranged from 23 to 100 years, with an average of 72.5 years. Two orthopaedic residents (observers Ⅰ and Ⅱ) and two senior orthopaedic surgeons (observers Ⅲ and Ⅳ) were selected to classify the CT imaging data of 616 patients in a random order by using the AO/Orthopaedic Trauma Association (AO/OTA) classification of 1996/2007 edition, the AO/OTA classification of 2018 edition, and the novel comprehensive classification method at an interval of 1 month. Kappa consistency test was used to evaluate the intra-observer and inter-observer consistency of the three ITF classification systems.@*RESULTS@#The inter-observer consistency of the three classification systems evaluated by 4 observers twice showed that the 3 classification systems had strong inter-observer consistency. Among them, the κ value of the novel comprehensive classification was higher than that of the AO/OTA classification of 1996/2007 edition and 2018 edition, and the experience of observers had a certain impact on the classification results, and the inter-observer consistency of orthopaedic residents was slightly better than that of senior orthopaedic surgeons. The intra-observer consistency of two evaluations of three classification systems by 4 observers showed that the consistency of the novel comprehensive classification was better for the other 3 observers, except that the consistency of observer Ⅳ in the AO/OTA classification of 2018 version was slightly higher than that of the novel comprehensive classification. The results showed that the novel comprehensive classification has higher repeatability, and the intra-observer consistency of senior orthopaedic surgeons was better than that of orthopaedic residents.@*CONCLUSION@#The novel comprehensive classification system has good intra- and inter-observer consistency, and has high validity in the classification of CT images of ITF patients; the experience of observers has a certain impact on the results of the three classification systems, and those with more experiences have higher intra-observer consistency.

Interpretations of Management of Hip Fractures in Older Adults:Evidence-Based Clinical Practice Guideline dopted by AAOS 2021 / 中国骨伤

American Academy of Orthopaedic Surgeons (AAOS) just released the up-to-date <Management of Hip Fractures in Older Adults:Evidence-Based Clinical Practice Guideline>, which has become the principles to care hip fractures in the elderly. In comparison to the Guideline 2014, considerable changes are made in terms of guideline composition and focused items. The interval of 7 years yielded dramatic progress in the care of geriatric hip fractures, including the recommendation of cemented femoral stems in hip arthroplasty due to displaced femoral neck fractures, cephalomedullary device for unstable intertrochanteric fractures and tranexamic acid to reduce blood loss and blood transfusion. Additionally, the individualized properties of the elderly with hip fractures should be noted to balance an early operation within 24 and 48 hours and patient safety. The interpretation of <Management of Hip Fractures in Older Adults:Evidence-Based Clinical Practice Guideline> is helpful to comprehensively understand the progress of the care of geriatric hip fractures, thus to make orthopaedic surgeons master the key points of clinical practice, and to improve the quality of operations and decrease perioperative complications.

Prediction of internal fixation failure of femoral trochanteric fracture by external wall morphology / 中国骨伤

OBJECTIVE@#To investigate the relationship between the shape of the lateral wall and the early failure of internal fixation in the fracture of the femoral trochanteric region(FFT).@*METHODS@#Total 295 patients with femoral trochanteric fracture underwent internal fixation from January 2015 to January 2020 were selected. The patients were divided into two groups according to whether there was early internal fixation failure after surgery, 19 patients in the failure group and 276 patients in the normal group. Gender, affected side, age, AO classification, body mass index(BMI), preoperative hemoglobin, X-ray measurement of lower lateral wall thickness, preoperative internal diseases, intraoperative blood loss, postoperative tip apex distance(TAD), postoperative neck shaft angle, operation time and other data were compared between two groups. The shape of the lateral wall was compared between two groups, and the correlation between the shape of the lateral wall and the early internal fixation failure of femoral trochanteric fracture was analyzed.@*RESULTS@#All patients were followed up for more than 1 year. There was no significant difference between two groups in terms of intraoperative blood loss, operation time, postoperative TAD, and postoperative neck shaft angle(P>0.05). At the latest follow-up, the visual anaglue scale (VAS) of the failure group was higher than that of the normal group(P<0.01), and the Harris score of the failure group was lower than that of normal group(P<0.05). The receiver operator characteristic (ROC) curve between shape of lateral wall and failure of early internal fixation of femoral trochanteric fracture was drawn. The critical value of the midpoint lateral wall thickness was 16.5 mm, and the area under the ROC curve was 0.845;The critical value of average sidewall thickness was 16.5 mm, and the area under ROC curve was 0.838;The critical value of the axial area of the sidewall was 7.5 mm, and the area under the ROC curve was 0.826.@*CONCLUSION@#The shape of the lateral femoral wall measured by CT could be used as a predictive factor for the early failure of internal fixation of femoral trochanteric fractures. For patients at risk, more reasonable surgical plans and postoperative preventive measures should be developed.

En 60 individuos (47,6 %) la lateralización del fémur estuvo entre 92,6 - 117,7 mm. Las medidas son independientes del sexo; a medida que aumenta la edad, el ángulo cervicodiafisario es menor (p= 0,021). Se realizaron tablas percentiladas de las medidas radiológicas del extremo proximal del fémur, según edad y sexo, que pueden servir de referencia en pacientes futuros(AU)

The objective of this work is to determine the radiological measurements of the proximal end of the femur in adult patients whose cases were presented in the clinical-radiological discussions of the Traumatology and Orthopedics service of the Central Hospital of San Cristóbal between 2015 and 2021. A prospective study was carried out, descriptive, crosssectional, which included radiological studies of a healthy hip in anteroposterior projection of the pelvis centered on the pubis with internal rotation of 15%, of 126 patients between 20 and 95 years of age. The following were measured: cervicodiaphyseal angle, femoral lateralization, length and width of the femoral neck, and diameter of the head circumference, using the MicroDicom DICOM 4.0.0 software. The mean neck-diaphyseal angle was 130.8 ± 4.5 degrees, in 57 individuals (45.2%) it was between 127.4 and 133.3 degrees (p = 0.001); the mean head circumference was 42.0 ± 2.4 mm, in 60 people (47.6%) it was between 40.2 and 45.7 mm (p = 0.001); the mean cervical length was 78.6 ± 16.4 mm, in 54 individuals (42.9 %) it was between 69.4 and 92 mm (p = 0.001); the mean cervical width was 75.9 ± 12.1 mm, in 64 cases (50.8%) it was between 62.9 and 78.7 mm (p= 0.001). In 60 individuals (47.6%), the lateralization of the femur was between 92.6 - 117.7 mm. The measurements are independent of sex; as age increases, the cervical shaft angle is less (p= 0.021). Percentage tables of the radiological measurements of the proximal end of the femur were made, according to age and sex, which can serve as a reference in future patients(AU)

The Impact of Hip Fractures in the Public Health System in Brazil (SUS) 2008 - 2017: The Orthopedist Task / O impacto das fraturas do quadril no SUS 2008 - 2017: O papel do ortopedista

Abstract Objective The present study intends to describe the profile of hospitalization and ambulatory rehabilitation of patients ≥ 50 years old due to hip fracture in the Brazilian Public Health System (SUS, in the Portuguese acronym). Methods This is a cross-sectional study of patients hospitalized due to hip fracture in the SUS between 2008 and 2017. Data included 441,787 hip fracture-related hospitalizations from the hospitalization database of the department of informatics of the Brazilian Unified Health System (SIH/DATASUS, in the Portuguese acronym), and data of patients who underwent rehabilitation from the ambulatory database of the department of informatics of the Brazilian Unified Health System (SIA/DATASUS, in the Portuguese acronym.). Results Most of hip fracture-related hospitalizations (83.5%) happen to people ≥ 50 years old, with an average annual growth of 5.6% in hip fracture-related hospitalizations. The costs for the government have been growing in the same proportion and reached almost BRL 130 million in 2017, although with a 13.6% decrease in average cost per hospitalization. Besides the financial impact, hip fractures result in an in-hospital mortality rate around 5.0% in patients aged ≥ 50 years old. In addition, the percentage of patients that have undergone hip fracture-related rehabilitation increased from 2008 (14.0%) to 2012 (40.0%), and remained stable after that. Conclusions The progressive increase in the incidence of hip fractures shows the financial and social impact, and the need for immediate actions to prevent this rising trend. Hip fractures are a risk for secondary fractures, the prevention is crucial, and the orthopedist plays a central role in this process.

Os custos para o governo cresceram na mesma proporção e atingiram quase 130 milhões de reais em 2017, embora com uma redução de 13,6% no custo médio por hospitalização. Além do impacto financeiro, as fraturas de quadril resultam em uma taxa de mortalidade hospitalar em torno de 5,0% em pacientes ≥ 50 anos. Além disso, o percentual de pacientes submetidos à reabilitação relacionada à fratura de quadril aumentou de 2008 (14,0%) para 2012 (40,0%) e permaneceu estável após esse período. Conclusões O aumento progressivo da incidência de fraturas de quadril mostra o impacto financeiro e social e a necessidade de ações imediatas para evitar essa tendência crescente. As fraturas de quadril são um risco para fraturas secundárias, a prevenção é crucial e o ortopedista desempenha um papel central nesse processo.

Intracapsular Femoral Neck Fractures in the Elderly / Fraturas intracapsulares do colo femoral no idoso

Abstract Currently, intracapsular femoral neck fracture (IFNF) is still a great challenge for orthopedists. In spite of the progress that has been made, a high mortality rate persists in the first year, especially in Brazil, where there is no awareness that such fractures in elderly patients should be treated as amedical emergency. The present article seeks to provide an update on the preoperative, surgical, and postoperative approaches.

Resumo Atualmente, a fratura intracapsular do colo femoral (FICF) ainda é um grande desafio para os ortopedistas. Apesar dos grandes avanços feitos, persiste uma grande taxa de mortalidade no primeiro ano, sobretudo no Brasil, onde não há uma conscientização de que tais fraturas nos pacientes idosos devemser tratadas como uma urgênciamédica. O presente artigo busca fornecer uma atualização das condutas pré-operatórias, cirúrgicas e pós-operatórias.

Low serum levels of vitamin D significantly increase the risk of death in older adults with hip fractures: a prospective cohort / Baixos níveis séricos de vitamina D aumentam significativamente o risco de morte em idosos com fraturas de quadril: coorte prospectiva

ABSTRACT Objective: to evaluate the relationship between 25(OH)D3 levels and fatal outcome in patients over 60 years of age undergoing surgical repair of hip fractures. Methods: prospective cohort of patients undergoing surgical repair of hip fractures. At admission, 25(OH)D3 levels were measured, among other parameters. Patients were followed for at least 1 year, and incident mortality was recorded. Results: 209 patients were included in the study, with a mean age of 79.5 ± 7.6 years among survivors and 80.7 ± 8.2 years among those who died in the first postoperative year (p=0.346). The 25(OH)D3 levels of survivors were significantly higher than those of patients who died (p=0.003). After adjusting for confounding variables, 25(OH)D3 levels below 12.5ng/mL were significant risk factors regardless of mortality (adjusted OR: 7.6; 95% CI: 2.35 to 24.56). Conclusions: our data show that serum 25(OH)D3 levels below 12.5ng/mL significantly and independently increased the risk of mortality in the first year after surgical repair of low-energy hip fracture in patients over 60 years of age in the geographic region where this study was conducted. Low albumin also showed a significant association with mortality in these patients. All other factors had no significant associations.

RESUMO Objetivo: avaliar a relação entre os níveis de 25(OH)D3 e o desfecho fatal em pacientes acima de 60 anos submetidos a correção cirúrgica de fratura de quadril. Métodos: coorte prospectiva de pacientes submetidos a correção cirúrgica de fraturas de quadril. À admissão, foram medidos os níveis de 25(OH)D3, entre outros parâmetros. Os pacientes foram acompanhados por, pelo menos, um ano e a mortalidade foi registrada. Resultados: foram incluídos 209 pacientes no estudo, com média de idade de 79,5 ± 7,6 anos entre os sobreviventes e 80,7 ± 8,2 anos entre os que morreram no primeiro ano de pós-operatório (p=0,346). Os níveis de 25(OH)D3 dos sobreviventes foram significativamente maiores do que os dos pacientes que morreram (p=0,003). Após o ajuste para variáveis de confusão, níveis de 25(OH)D3 abaixo de 12,5ng/mL foram fator de risco significativo, independentemente da mortalidade (OR ajustado 7,6; IC 95% 2,35 24,56). Conclusões: níveis séricos de 25(OH)D3 abaixo de 12,5ng/mL aumentaram significativa e independentemente o risco de morte no primeiro ano após o reparo cirúrgico de fratura de quadril de baixa energia em pacientes com mais de 60 anos de idade na região geográfica onde este estudo foi realizado. A albumina baixa também teve associação significativa com a mortalidade nesses pacientes. Todos os outros fatores não tiveram associações significativas.

Psychometric properties of the Chinese version of the Positive Thinking Scale in individuals after hip fracture surgery

Positive thinking is a form of positive cognition and a coping strategy. The Positive Thinking Scale (PTS) is used to measure positive thinking, but the reliability and validity of the PTS-Chinese have yet to be tested. This study aims to examine the psychometric properties of the PTS-Chinese. A total of 154 patients post-hip fracture surgery completed the questionnaire in a hospital in Taiwan between April 2020 and December 2020. The scales in the questionnaire included the PTS, Automatic Thoughts Questionnaire-Positive, Automatic Thoughts Questionnaire-Negative, Barthel Index, and items related to happiness, demographics, and disease treatment. The results of the confirmatory factor analysis and average variance extracted show that the PTS-Chinese version exhibits construct validity. Scores on the PTS-Chinese version are positively related to scores on the Automatic Thoughts Questionnaire-Positive and happiness items and negatively related to scores on the Automatic Thoughts Questionnaire-Negative. This finding indicates that the PTS-Chinese demonstrates concurrent, predictive, and discriminant validity. The scale also presents acceptable reliability and test-retest reliability. Overall, the PTS-Chinese can be used to evaluate and track the positive thinking of patients. Further studies are needed to assess the psychometric properties of the PTS-Chinese in different cultures and ethnic groups. (AU)

Medium-term mortality after hip fractures and COVID-19: A prospective multi-centre UK study / 中华创伤杂志(英文版)

PURPOSE@#The COVID-19 pandemic has caused 1.4 million deaths globally and is associated with a 3-4 times increase in 30-day mortality after a fragility hip fracture with concurrent COVID-19 infection. Typically, death from COVID-19 infection occurs between 15 and 22 days after the onset of symptoms, but this period can extend up to 8 weeks. This study aimed to assess the impact of concurrent COVID-19 infection on 120-day mortality after a fragility hip fracture.@*METHODS@#A multi-centre prospective study across 10 hospitals treating 8% of the annual burden of hip fractures in England between 1st March and 30th April, 2020 was performed. Patients whose surgical treatment was payable through the National Health Service Best Practice Tariff mechanism for "fragility hip fractures" were included in the study. Patients' 120-day mortality was assessed relative to their peri-operative COVID-19 status. Statistical analysis was performed using SPSS version 27.@*RESULTS@#A total of 746 patients were included in this study, of which 87 (11.7%) were COVID-19 positive. Mortality rates at 30- and 120-day were significantly higher for COVID-19 positive patients relative to COVID-19 negative patients (p < 0.001). However, mortality rates between 31 and 120-day were not significantly different (p = 0.107), 16.1% and 9.4% respectively for COVID-19 positive and negative patients, odds ratio 1.855 (95% CI 0.865-3.978).@*CONCLUSION@#Hip fracture patients with concurrent COVID-19 infection, provided that they are alive at day-31 after injury, have no significant difference in 120-day mortality. Despite the growing awareness and concern of "long-COVID" and its widespread prevalence, this does not appear to increase medium-term mortality rates after a hip fracture.

A rare complication of pelvic perforation by an excessive medial slide of the helical blade after treatment of an intertrochanteric fracture with proximal femoral nail anti-rotation: A case report and literature review / 中华创伤杂志(英文版)

Intertrochanteric fractures have become a severe public health problem in elderly patients. Proximal femoral nail anti-rotation (PFNA) is a commonly used intramedullary fixation device for unstable intertrochanteric fractures. Pelvic perforation by cephalic screw is a rare complication. We reported an 84-year-old female who fell at home and sustained an intertrochanteric fracture. The patient underwent surgery with PFNA as the intramedullary fixation device. Routine postoperative examination revealed medial migration of the helical blade that eventually caused pelvic perforation. We performed a cemented total hip arthroplasty as the savage procedure. At the latest follow-up of 12 months after total hip arthroplasty, the patient had no pain or loosening of the prosthesis in the left hip. Pelvic perforation should be considered when choosing PFNA as the intramedullary fixation device, especially in patients with severe osteoporosis wherein the helical blade can be easily inserted during the operation. The lack of devices to avoid oversliding of the helical blade in PFNA is an unreported cause of this complication and should be considered in such cases.

Analysis of risk factors for readmission in elderly patients with hip fractures undergoing hip hemiarthroplasty / 中国骨伤

OBJECTIVE@#To explore the incidence and risk factors of readmission of elderly patients with hip fracture after hip hemiarthroplasty.@*METHODS@#A retrospective analysis of 237 elderly hip fracture patients who underwent hip hemiarthroplasty from February 2015 to October 2020 were performed. According to the readmission status of the patients at 3 months postoperatively, the patients were divided into readmission group (39 cases)and non-readmission group(198 cases). In readmission group, there were 7 males and 32 females with an average age of(84.59±4.34) years old, respectively, there were 34 males and 164 females with average age of (84.65±4.17) years old in non-readmission group. The general information, surgical status, hip Harris score and complications of patients in two groups were included in univariate analysis, and multivariate Logistic regression was used to analyze independent risk factors of patients' readmission.@*RESULTS@#The proportion of complications(cerebral infarction and coronary heart disease) in readmission group was significantly higher than that of non-readmission group (P<0.05), and intraoperative blood loss in readmission group was significantly higher than that of non-readmission group(P<0.05). Harris score of hip joint was significantly lower than that of non-readmission group(P<0.05). The proportion of infection, delirium, joint dislocation, anemia and venous thrombosis in readmission group were significantly higher than that of non-readmission group (all P<0.05). Multivariate Logistic regression analysis showed that the risk factors for readmission of elderly patients with hip fracture after hip hemiarthroplasty included cerebral infarction, infection, delirium, dislocation, anemia and venous thrombosis (all P<0.05).@*CONCLUSION@#The complications of the elderly patients who were readmission after hip hemiarthroplasty for hip fractures were significantly higher than those who were non-readmission. Cerebral infarction, infection, delirium, dislocation, anemia and venous thrombosis are risk factors that lead to patient readmission. Corresponding intervention measures can be taken clinically based on these risk factors to reduce the incidence of patient readmissions.
