ABSTRACT

OBJECTIVE@#To compare the efficacy between vesselplasty and percutanous kyphoplasty (PKP) in the treatment of Kümmell disease.@*METHODS@#The clinical data of patients with Kümmell disease from July 2018 to December 2019 were retrospectively analyzed. According to the different therapeutic methods, the patients were divided into vesselplasty group and PKP group. There were 20 patients in vesselplasty group, including 2 males and 18 females, aged from 54 to 83 years with an average of (67.40±7.44)years, 1 case of T10 fracture, 3 cases of T12 fracture, 9 cases of L1 fractures, 5 cases of L2 fractures and 2 cases of L3 fractures. There were 20 patients in PKP group, including 3 males and 17 females, aged from 56 to 81 with an average of(67.20±7.01) years, 2 cases of T10 fracture, 1 case of T11 fracture, 6 cases of T12 fracture, 10 cases of L1 fracture and 1 case of L3 fracture. Visual analogue scale(VAS), Cobb angle, anterior vertebral height were recorded before operation, 1 day after operation and 1 year after operation. Oswestry Disability Index(ODI) was recorded before operation, 1 month after operation and 1 year after operation. And bone cement leakage rate was compared between two groups after operation.@*RESULTS@#All the patient were followed up for more than 1 year. In vesselplasty group, VAS score was 1.20±0.41, ODI was(13.50±3.10)%, Cobb angle was(17.20±3.12)° and anterior vertebral height was(20.20±1.35) mm at 1 year after operation. In PKP group, VAS score was 1.15±0.40, ODI was (13.20±3.00)%, Cobb angle was (17.10±3.19)° and anterior vertebral height was (20.10±1.37) mm at 1 year after operation. These index was significantly better than pre-operation through intra-group comparison(P<0.05), and there was no statistically difference between the two groups(P>0.05). There were 20 cases (20 vertebrae) in vesselplasty group, of which 1 case had bone cement leakage at the upper endplate, with a leakage rate of 5%(1/20). In PKP group, there were 20 cases (20 vertebrae), 3 cases of upward endplate leakage(3/7), 1 case of downward endplate leakage(1/7), 1 case of leakage to the front of the vertebral body(1/7), 2 cases of leakage to the side of the vertebral body(2/7), with a leakage rate of 35% (7/20). The difference between two groups was statistically significant(P<0.05).@*CONCLUSION@#Vesselplasty in the treatment of Kümmell disease can better reduce leakage rate of bone cement and reduce complications.

ABSTRACT

OBJECTIVE@#To investigate the effects of different bone cement morphology distribution on the clinical efficacy of unilateral percutaneous vertebroplasty(PVP) for spinal osteoporotic fractures.@*METHODS@#The clinical data of 66 patients with osteoporotic vertebral compression fractures received unilateral PVP treatment from January 2019 to April 2020 were retrospectively analyzed. There were 16 males and 50 females, including 83 vertebral bodies, 45 thoracic vertebrae and 38 lumbar vertebrae, and 55 patients with single-segment, 6 double-segment, 4 three-segment and 1 four-segment. The age ranged from 60 to 93 years with an average of (76.83±8.65) years. The included patients were admitted to hospital 1 to 10 days after onset, and were diagnosed by anteroposterior and lateral X-rays, MRI and bone density examination before surgery. According to the shape of bone cement in postoperative X-ray, the patients were divided into O-shaped group (28 cases) and H-shaped group (38 cases). In O-shaped group, the bone cement presented agglomeration mass distribution in the affected vertebra in postoperative X-ray while the bone cement presented disseminated honeycomb distribution in the affected vertebrae in H-shaped group. Bone cement injection volume was collected in two groups. The intraoperative bone cement leakage and postoperative adjacent vertebral fractures were observed. The VAS of the two groups before operation and 1 day, 1 month, 6 months and 1 year after operation were compared;and ODI of the two groups 1 day, 6 months and 1 year after operation were compared. The kyphosis angle and anterior height of the affected vertebrae were measured before operation and 1 week, 1 year after operation.@*RESULTS@#All 66 patients completed 1-year follow-up, and all patients healed well at the puncture site after surgery. There were 1 case and 8 cases of bone cement leakage in O-shaped group and H-shaped group during surgery respectively (P<0.05), but no serious complications occurred. One case occurred adjacent vertebral fracture in both groups during one-year follow-up (P>0.05). There was no statistical significance in injection amount of bone cement between the two groups (P>0.05). The VAS scores of O-shaped group and H-shaped group were 7.89±0.79, 2.75±1.08, 0.46±0.58, 0.36±0.49 and 8.00±1.04, 2.58±1.15, 0.53±0.56, 0.42±0.50 before operation, 1 day, 6 months, 1 year after operation respectively, and there was no statistical significance(P>0.05), and the VAS scores were 0.96±0.58 and 1.18±0.83 at 1 month after operation respectively, with statistical significance(P<0.05). The ODI scores of O-shaped group and H-shaped group were 12.43±3.78, 10.00±2.46, 8.43±1.50 and 12.11±3.68, 9.53±2.35, 8.32±1.51 at 1 day, 6 months and 1 year after surgery respectively, and there was no statistical significance between the two groups(P>0.05). There were no statistical significance in kyphotic angles and anterior height before surgery and 1 week, 1 year after surgery between two groups (P>0.05).@*CONCLUSION@#No matter the distribution of bone cement is O-shape or H-shape, it can achieve good clinical effect, and the prognosis effect is equivalent. Therefore, when performing unilateral puncture PVP surgery, it is not necessary to deliberately increase the puncture angle of the puncture needle in order to achieve the full diffusion of the affected vertebrae, so as to reduce the risk of damaging important structures and bone cement leakage.

ABSTRACT

OBJECTIVE@#To analyze the efficacy of percutaneous vertebroplasty for osteoporotic vertebral compression fractures with spinal origin abdominal pain as the main symptom.@*METHODS@#A retrospective analysis was performed on 37 patients with osteoporotic vertebral compression fractures treated from January 2015 to January 2021, all of whom had spin-derived abdominal pain as the main symptom, and were divided into surgery group(21 cases) and conservative group (16 cases) according to different treatment methods. Patients in the surgery group were treated with percutaneous vertebroplasty, including 7 males and 14 females, with an average age of (75.95±6.84) years old and an average course of disease of (5.26±3.79) days. The conservative group received non-surgical treatment, including 5 males and 11 females, with an average age of (75.50±8.07) years old and an average course of disease of (4.28±3.42) days. Two groups of patients with preoperative mainly characterized by abdominal pain, abdominal distension and constipation, have no obvious chest waist back pain symptoms, the thoracolumbar MRI diagnosed as fresh osteoporotic vertebral compression fractures, record its postoperative abdominal pain visual analogue scale (VAS), medical outcomes study short form-36 (SF-36) score, defecation interval after treatment, etc.@*RESULTS@#Thirty-seven patients were followed up for (14.90±14.11) months in surgery group and( 21.42±17.53) months in conservative group. Compared with before treatment, the VAS of surgery group at each time period after treatment, VAS of conservative group at 1 month after treatment and SF-36 score between two groups at 3 months after treatment were all improved(P<0.05), while VAS of conservative group at 3 days after treatment showed no statistically significant difference(P>0.05). Compared between two groups, there were no significant differences in VAS and SF-36 scores at 1 day before treatment(P>0.05), but VAS at 3 days after treatment in surgery group, life vitality and social function score at 3 months after treatment, and defecation time after treatment in surgery group were better than those in conservative group(P<0.05). There were no significant differences in other indexes(P>0.05). The incision healing of patients in surgery group was good, and no serious complications occurred in both groups.@*CONCLUSION@#Percutaneous vertebroplasty is an effective method for the treatment of osteoporotic vertebral compression fractures with spinal origin abdominal pain as the main symptom. Compared with conservative treatment, percutaneous vertebroplasty has more advantages in early relief of abdominal pain and constipation, recovery of vitality and social function.

ABSTRACT

OBJECTIVE@#Taking the classic bilateral puncture vertebroplasty as a reference, to evaluate the clinical efficacy of vertebroplasty of the curved-angle puncture device, analyze the radiation exposure of patients and surgeons during the operation and summarize the protective measures.@*METHODS@#The clinical data of 49 patients with osteoporotic vertebral compression fractures admitted from March 2018 to September 2019 were retrospectively analyzed. According to the different surgical puncture methods, 49 patients were divided into vertebroplasty group (using classic bilateral puncture) and curved vertebroplasty group (using curved angle puncture). Among them, there were 26 cases in vertebroplasty group, including 7 males and 19 females, aged (73.25±6.36) years, 2 cases in thoracic segment, 21 cases in thoracolumbar segment, and 3 cases in lumbar segment. In curved vertebroplasty group, there were 23 cases, including 6 males and 17 females, aged (73.09±6.52) years, 3 cases in thoracic segment, 19 cases in thoracolumbar segment, and 1 case in lumbar segment. The operation time and the amount of injected bone cement in the two groups were recorded. Visual analogue scale (VAS) and modified Oswestry Disability Index (ODI) were respectively used to assess the pain degree and lumbar function, the postoperative bone cement leakage or other complications were observed. The radiation doses of the two groups of patients and surgeons were compared.@*RESULTS@#All 49 patients were followed up for 10-22 (14.55±3.83) months. Eleven cases in vertebroplasty group and 9 cases in curved vertebroplasty group occurred bone cement leakage after surgery, and there was no statistically significant difference between two groups. VAS scores of vertebroplasty group were 6.23±0.68 before operation and 1.69±0.47 at 1 day after operation, respectively, modified ODI were (72.59±3.25)% and (33.59±2.85)%. The preoperative and postoperative VAS scores of curved vertebroplasty group were 6.46±0.56 and 1.57±0.49, respectively, modified ODI were (73.21±3.18)% and (33.17±2.37)%. The postoperative pain degree and lumbar function of the two groups were significantly improved, but the difference between the groups was not statistically significant. The operation time of curved vertebroplasty group and vertebroplasty group were (17.27±9.58) min and(23.19±8.56) min, and the amount of injected bone cement were (4.91±1.49) ml and (6.58±1.42) ml. Obviously, curved vertebroplasty group has more advantages in operation time and the amount of injected bone cement. In curved vertebroplasty group, the radiation dose of the operator was (0.53±0.05) mSv and the patient was (10.64±1.65) mSv;in vertebroplasty group, the operator was (0.59±0.08) mSv andthe patient was (13.52±1.81) mSv. The radiation dose of patients in curved vertebroplasty group was significantly lower than that of the vertebroplasty group, but there was no statistically significant difference in the operator between two groups.@*CONCLUSION@#Both puncture methods can achieve satisfactory clinical results, but curved angle puncture can optimize the distribution of bone cement and reduce the radiation dose of patients.

ABSTRACT

OBJECTIVE@#To explore the methods and efficacy of unilateral extra-pedicle precision puncture percutaneous vertebroplasty (PVP) or percutaneous kyphoplasty(PKP) by digital subtraction angiography (DSA) for the treatment of osteoporotic vertebral compression fractures (OVCFs).@*METHODS@#The clinical data of 68 patients with osteoporotic vertebral compression fractures treated from August 2015 to December 2018 were retrospectively analyzed. There were 20 males and 48 females, aged 56 to 90(73.5±8.0) years, 40 cases of double segments, 28 cases of three segments, a total of 168 vertebrae. All the patients were performed PVP orPKP through unilateral extra pedicle precision puncture under the guidance of DSA. The vertebrae were distributed in T@*RESULTS@#All the punctures were successful in 68 patients. All the puncture needles reached the midline of vertebral body, and the bone cement was well dispersed in the vertebral body with symmetrical distribution. The operation time was 35 to 60 (41.6±3.2) minutes, and there was no puncture complications. The injection volume of bone cement was 3 to 5 (3.6±0.5) ml in each vertebra. There were 8 cases of bone cement leakage, with a leakage rate of 11.76%. All 68 patients were followed up from 12 to 27 (14.3±3.5) months in the study. VAS score and ODI at 3 days after surgery and at final follow-up time were significantly improved (@*CONCLUSION@#PVP or PKP under the guidance of DSA via a unilateral extrapedicular approach with precision puncture can effectively relieve pain, restore vertebral body height and spinal function, which is a safe, fast and effective method in the treatment of osteoporotic vertebral compression fractures.

ABSTRACT

OBJECTIVE@#To investigate the risk factors of vertebral refracture after percutaneous kyphoplasty (PKP) for osteoprotic vertebral compression fractures (OVCFs), and to provide reference for clinical prevention.@*METHODS@#A retrospective analysis of 228 OVCFs patients who met the inclusion criteria admitted from November 6, 2013 to December 14, 2018. There were 35 males and 193 females, with a male-to-female ratio of 3∶20, and aged 58 to 91 years with an average of (69.70±7.03) years. All patients were treated with PKP and had complete clinical data. According to whether refracture occurred after operation, they were divided into refracture group (24 cases) and non refracture group (204 cases). Factors that may be related to refracture (including gender, age, surgical segment, number of vertebral bodies in the surgical segment, whether combined with degenerative scoliosis, whether anti-osteoporosis treatment) were included in the univariate analyses, and the single factor analysis of statistically significant risk factors was carried out with multiple Logistic regression analysis to further clarify the independent risk factors for vertebral body refracture after PKP. Survival analysis was performed using the time of vertebral refracture after PKP as the end time of follow up, the occurrence of refracture after PKP as the endpoint event, and the presence or absence of degenerative lateral curvature as a variable factor.@*RESULTS@#All 228 patients were followed up for 1.8 to 63.6 months with an average of (28.8±15.6) months, and the refracture rate was 10.5%(24/228). There were statistically significant differences between two groups in age, number of operative vertebral bodies, whether combinedwith degenerative scoliosis and whether anti osteoporosis treatment (@*CONCLUSION@#Combined scoliosis is an independent risk factor for refracture after OVCFs vertebroplasty, and it is also a possible high-risk factor for refracture after surgery.

ABSTRACT

OBJECTIVE@#To establish a three-dimensional finite element model of osteoporosis and to study the stiffness recovery of injured vertebrae and stress analysis of adjacent vertebrae after percutaneous vertebroplasty under different perfusion and distribution conditions by simulating fluid flow into the vertebral body.@*METHODS@#A male healthy volunteer was selected. CT scans were performed from T@*RESULTS@#(1) The VonMises stress of T@*CONCLUSION@#Reliable biomechanical model of lumbar vertebral fracture can be established by using CT scanning data through software simulation. Vertebral fracture and vertebroplasty will cause biomechanical changes of adjacent vertebral bodies. With the increase of bone cement injection, the influence of biomechanical changes will increase significantly. Neighbouring vertebral fractures are more likely. For this experiment, percutaneous vertebroplasty has a suitable amount of cement injection of 4 ml.

ABSTRACT

OBJECTIVE@#To study effects of postoperative regular training of core muscle strength guided by the concept of enhanced recovery after surgery (ERAS) on the rehabilitation of elderly patients with osteoporotic lumbar vertebral compression fracture after vertebroplasty (PVP) and kyphoplasty(PKP).@*METHODS@#Ninety-four elderly patients with osteoporotic lumbar compression fractures who underwent PKP or PVP from January 2016 to January 2018 and met inclusion criteria were divided into observation group and control group. All the patients were treated with routine anti osteoporosis therapy after operation. There were 47 patients in the observationgroup, including 18 males and 29 females, with an average age of (62.62±3.21) years old;in the control group, there were 47 cases, including 17 males and 30 females, with an average age of (62.38±2.84) years old. The patients in the control group were trained by traditional way, and the patients in observation group were instructed to conduct regular training of core muscle strength according to ERAS concept. The patients were followed up for 1, 3 and 6 months after operation. Patients' conditions were quantitatively evaluated according to Barthel scale, JOA low back pain score and Oswestry Disability Index, and the differences in treatment effects between two groups were statistically analyzed and compared.@*RESULTS@#All the patients were followed up, and the Barthel scale, JOA low back pain score and Oswestry Disability Index score of the observation group were all better than those of the control group on the 1st and the 3rd months after surgery(@*CONCLUSION@#Early regular core strength training has a positive effect on early functional recovery and improvement of life ability after PKP or PVP for elderly patients with osteoporotic lumbar compression fractures, which is in line with the concept of accelerated rehabilitation surgery.

ABSTRACT

OBJECTIVES: Osteoporotic vertebral compression fractures (OVCFs) affect the elderly population, especially postmenopausal women. Percutaneous kyphoplasty is designed to treat painful vertebral compression fractures for which conservative therapy has been unsuccessful. High-viscosity cement can be injected by either a hydraulic pressure delivery system (HPDS) or a balloon tamp system (BTS). Therefore, the purpose of this study was to compare the safety and clinical outcomes of these two systems. METHODS: A random, multicenter, prospective study was performed. Clinical and radiological assessments were carried out, including assessments of general surgery information, visual analog scale, quality of life, cement leakage, and height and angle restoration. RESULTS: Using either the HPDS or BTS to inject high-viscosity cement effectively relieved pain and improved the patients' quality of life immediately, and these effects lasted at least two years. The HPDS using high-viscosity cement reduced cost, surgery time, and radiation exposure and showed similar clinical results to those of the BTS. In addition, the leakage rate and the incidence of adjacent vertebral fractures after the HPDS treatment were reduced compared with those after treatment using the classic vertebroplasty devices. However, the BTS had better height and angle restoration abilities. CONCLUSIONS: The percutaneous HPDS with high-viscosity cement has similar clinical outcomes to those of traditional procedures in the treatment of vertebral fractures in the elderly. The HPDS with high-viscosity cement is better than the BTS in the treatment of mild and moderate OVCFs and could be an alternative method for the treatment of severe OVCFs.

ABSTRACT

Abstract Stiff Person Syndrome (SPS), typified by rigidity in muscles of the torso and extremities and painful episodic spasms, is a rare autoimmune-based neurological disease. Here we present the successful endotracheal intubation and application of TIVA without muscle relaxants on an SPS patient. A 46 years old male patient was operated with ASA-II physical status because of lumber vertebral compression fracture. After induction of anesthesia using lidocaine, propofol and remifentanil tracheal intubation was completed easily without neuromuscular blockage. Anesthesia was maintained with propofol, remifentanil and O2/air mixture. After a problem-free intraoperative period the patient was extubated and seven days later was discharged walking with aid. Though the mechanism is not clear neuromuscular blockers and volatile anesthetics may cause prolonged hypotonia in patients with SPS. We think the TIVA technique, a general anesthetic practice which does not require neuromuscular blockage, is suitable for these patients.


Resumo A síndrome da pessoa rígida (SPR), caracterizada pela rigidez dos músculos do tronco e das extremidades e por episódios de espasmos dolorosos, é uma doença neurológica autoimune rara. Apresentamos o ocaso de intubação endotraqueal bem-sucedida e aplicação de AVT sem relaxantes musculares em um paciente com SPR. Paciente do sexo masculino, 46 anos, estado físico ASA-II, submetido à cirurgia devido à fratura por compressão da coluna lombar. Após a indução da anestesia com lidocaína, propofol e remifentanil, a intubação traqueal foi concluída com facilidade, sem bloqueio neuromuscular. A anestesia foi mantida com propofol, remifentanil e mistura de ar/O2. Após o período intraoperatório, que transcorreu sem intercorrências, o paciente foi extubado e, sete dias depois, recebeu alta, deambulando com ajuda. Embora o mecanismo não esteja claro, bloqueadores neuromusculares e anestésicos voláteis podem causar hipotonia prolongada em pacientes com SPR. Acreditamos que a técnica de AVT, uma prática de anestesia geral que não requer bloqueio neuromuscular, é adequada para esses pacientes.

ABSTRACT

Purpose: To describe our experience with percutaneous balloon kyphoplasty for the treatment of non-traumatic vertebral compression fractures. Material and Methods: Between march 2007 and June 2008, 25 vertebrae interventions were performed in 10 patients. Ten cases corresponded to osteoporotic fractures, while fifteen of them revealed a tumoral etiology. Vertebral compromise was evaluated via CT scan or MRI, as appropriate. We applied a percutaneous technique. Balloons were inserted into the vertebral body, and then inflated to create a cavity to be filled with polymethylmethacrylate (PMMA), which reduces and stabilizes the fracture, thus reducing pain. Results: The technique was performed successfully in al I cases. Pain intensity assessed by Visual Analogue Scale (VAS) before and after the procedure showed a variation ranging from 4 to 7 levels per patient. The mean inicial VAS score was 7, whereas average final VAS was 1.2. The decrease in pain levels averaged 5.8 per intervention. Complications occurred in 7 levels: 3 cases of thoracic extravasations and 4 cases in lumbar spine. All of them were asymptomatic. No severe complications were reposed. Conclusions: Percutaneous balloon kyphoplasty offers a good alternative treatment to conservative pain management in vertebral compression fractures.


Propósito: Describir nuestra experiencia en cifoplastía percutanea con balón en fracturas vertebrales debidas a compresión no traumática. Material y Métodos: Se intervinieron 25 vértebras en 10 pacientes, 15 lumbares y 10 torácicas, entre marzo 2007 y junio 2008. La etiología de las fracturas fue osteoporótica en 10 casos y tumoral en 15. Se evaluó el compromiso vertebral mediante tomografía computada o resonancia magnética, según el caso. La técnica fue percutanea; se insertaron balones en el cuerpo vertebral, que se inflaron, creando así una cavidad que se relleno inyectando polimetilme-tacrilato (PMMA), que redujo y estabilizó la fractura, disminuyendo así el dolor. Resultados: La técnica fue realizada satisfactoriamente en todos los casos. La intensidad del dolor medida según la Escala Visual Análoga (EVA), antes y después del procedimiento, varió entre 4 y 7 niveles por paciente. El EVA de ingreso promedio fue de 7, y el de egreso de 1.2. La disminución del dolor fue en promedio 5.8 niveles por intervención. Hubo complicaciones en 7 niveles: 3 casos de extravasación torácica y 4 en columna lumbar, todas asintomáticas. No hubo complicaciones severas. Conclusiones: La cifoplastía con balón es una buena alternativa analgésica al manejo conservador en fracturas vertebrales por compresión.

ABSTRACT

OBJETIVO: Relatar a experiência com o acesso anterior em fraturas traumáticas do tipo compressão no segmento toracolombar (T11 a L2) que foram submetidos à cirurgia pelo acesso anterior. MÉTODO: Estudo prospectivo de janeiro de 1994 a janeiro de 2004 envolvendo 32 pacientes. A presença da fusão óssea e do alinhamento foram analisadas 6 e 12 meses após a cirurgia. RESULTADOS: A idade média foi 36,53 anos, sendo 23 do sexo masculino. A vértebra mais atingida foi L1 (n=12). A maioria dos casos que internaram em ASIA/IMSOP C (n=10) e D (n=13) evoluiram para ASIA/IMSOP E. A média da deformidade angular pré-operatória foi 14,9°±7,5°, com diferença estatística (p<0,0001) na comparação com o valor encontrado no pós-operatório de 30 dias. CONCLUSÃO: A via anterior permite melhor descompressão do canal e uma correção da deformidade angular superior à observada pela via posterior isolada.


OBJECTIVE: To describe experience with anterior access in compression fractures of thoracolumbar segment (T11 to L2) traumatic fractures that undergone anterior access surgery. METHOD: A prospective study was conducted between January 1994 and January 2004 with 32 patients. The bone fusion and thoracolumbar alignment were analyzed 6 months and 12 months after the surgery. RESULTS:The average age was 36.53 years old with 23 male patients. The most compromised vertebrae was L1 (n=12). The 23 patients that was ASIA/IMSOP C and ASIA/IMSOP D turned to ASIA/IMSOP E after 1 month (n=12) and 12 months (n=5) of surgery. The preoperative angular deformity average was 14.9°±7.5°. Statistical significance was found (p<0.0001) when compared to the 30 days postoperative value. CONCLUSION: The anterior access permits a better spinal canal decompression and angular deformity correction when compared with the posterior access alone.
