Abstract Objective: to investigate the effect of CT-assisted limited decompression in the management of single segment A3 lumbar burst fracture. Method: A retrospective study of 106 cases with a single-level Magerl type A3 lumbar burst fractures treated with short-segment posterior internal fixation and limited decompression from January 2015 to June 2019 was performed. Patients were divided into two groups: CT-assisted and non-CT-assisted. Perioperative factors, clinical outcomes, postoperative complications, imaging parameters and health-related quality of life (HRQoL) were evaluated. Results: There was no significant difference between the two groups in the kyphosis, anterior vertebral body height loss, posterior vertebral body height loss, operative time, and postoperative complications. The visual analogue score (VAS) and spinal canal encroachment in the CT-assisted group were lower than those in the non-CT-assisted group (P < 0.05). The Japanese Orthopaedic Association score (JOA), the simplified HRQoL scale and American Spinal Injury Association (ASIA) Spinal Cord Injury Grade in the CT-assisted group were higher than those in the non-CT-assisted group (P < 0.05).Conclusion: CT-assisted limited decompression in the treatment of single-segment A3 lumbar burst fracture can achieve better fracture reduction and surgical results, and improve the long-term recovery of neurological function and quality of life of the patients.

Background Percutaneous vertebral augmentation (PVA) is widely applied for the treatment of osteoporotic vertebral fractures. The degree of vertebral body height restoration and deformity correction after the procedure is not consistent. Methods We retrospectively reviewed 97 patients who underwent PVA, because of osteoporotic vertebral compression fractures. The following data about the patients were recorded: age, sex, bone density, number of treated vertebrae, severity of fracture of the treated vertebrae, operative approach (PVP or PKP), volume of injected bone cement, preoperative vertebral compression ratio, preoperative local kyphosis angle, cement leakage, postoperative vertebral body height restoration ratio, follow-up period, and latest follow-up height loss ratio. Bivariate regression analysis and t-test were applied for univariate analysis, while multivariate linear regression analysis was applied for multivariate analysis. Results The postoperative vertebral body height restoration ratio was (14.7% ± 15.2%), and the last follow-up height loss ratio was (13.5% ± 11.5%). The multivariate analysis showed that the number of treated vertebrae, preoperative vertebral compression ratio, and preoperative local kyphosis angle are the main factors influencing the postoperative vertebral body height restoration. The univariate analysis also showed that only the postoperative vertebral body height restoration ratio is related to the last follow-up height loss ratio. Conclusions The number of treated vertebrae, preoperative vertebral compression ratio, and preoperative local kyphosis angle are the main influencing factors of patients' vertebral body height restoration after PVA, and the postoperative vertebral body height restoration ratio is the main factor influencing the last follow-up height loss ratio.

The Relationship

BACKGROUND: The number of patients with an osteoporotic vertebral compression fracture, which is often accompanied by lower back pain and restrained activities, is growing. Balloon kyphoplasty involves the inflation of a balloon to restore height and reduce kyphotic deformity before stabilization with polymethylmethacrylate. However, there is a great deal of debate about whether balloon kyphoplasty also increases fracture morbidity by either inducing or facilitating subsequent adjacent vertebral fractures. OBJECTIVE: To evaluate the relationship between the rate of vertebral body height loss before balloon kyphoplasty and the etiology of early adjacent vertebral fracture after augmentation. METHODS: A total of 59 patients with osteoporotic vertebral compression fractures who underwent kyphoplasty were enrolled. This study defined early adjacent segmental fractures as new fractures occurring within three months after surgery. This study included the rate of vertebral body height loss. RESULTS: Early adjacent vertebral fractures were diagnosed in nine (15%) of the 59 patients. The patients were divided into two groups, with and without adjacent vertebral fractures. There was no significant difference in terms of age, body mass index, bone mineral density, local kyphotic angle, Cobb’s angle, cement volume, cement leakage, and percent height restored between the groups with fractures and without fractures. There was a statistically significant difference between the two groups in the rate of vertebral body height loss. The rate of vertebral body height loss was significantly higher in the fracture group than in the without fracture group. CONCLUSIONS: A high rate of vertebral body height loss increased the risk of early adjacent vertebral fractures after balloon kyphoplasty.

Abstract Background: There is no consensus on the best choice between high- and low-viscosity bone cement for percutaneous vertebroplasty (PVP). This study aimed to compare the clinical outcomes and leakage between three cements with different viscosities in treating osteoporotic vertebral compression fractures.Methods: This is a prospective study comparing patients who were treated with PVP: group A (n = 99, 107 vertebrae) with high-viscosity OSTEOPAL V cement, group B (n = 79, 100 vertebrae) with low-viscosity OSTEOPAL V cement, and group C (n = 88, 102 vertebrae) with low-viscosity Eurofix VTP cement. Postoperative pain severity was evaluated using the visual analog scale. Cement leakage was evaluated using radiography and computed tomography.Results: There was no significant difference in the incidence of cement leakage between the three groups (group A 20.6%, group B 24.2%, group C 20.6%, P = 0.767). All three groups showed significant reduction in postoperative pain scores but did not differ significantly in pain scores at postoperative 2 days (group A 2.01 ± 0.62, group B 2.15 ± 0.33, group C 1.92 ± 0.71, P = 0.646). During the 6 months after cement implantation, significantly less reduction in the fractured vertebral body height was noticed in group B and group C than in group A (group A 19.0%, group B 8.1%, group C 7.3%, P = 0.009).Conclusions: Low-viscosity cement has comparable incidence of leakage compared to high-viscosity cement in PVP for osteoporotic vertebral compression fractures. It also can better prevent postoperative loss of vertebral body height.

Osteoporotic Vertebral Fractures

Abstract Changes in vertebral body height depend on various factors which were analyzed in isolation and not as a whole. The aim of this study is to analyze what factors might influence restoration of vertebral body height after vertebral augmentation. We analyzed 48 patients (108 vertebrae) with osteoporotic vertebral fractures underwent vertebral augmentation when conservative treatment proved unsatisfactory. Analyses were carried out at the time of the fracture, during surgery (pre-cementation and post-cementation), at first medical check-up (6 weeks post-surgery) and at last medical check-up. Average vertebral height was measured and differences from preoperative values calculated at each timepoint. Pearson correlation coefficient and linear multivariable regression were carried out at the different timepoints. The time since vertebral fracture was 60.4 ± 41.7 days. Patients’ average age was 70.9 ± 9.3-years. The total follow-up was 1.43 ± 1-year. After vertebral cementation there was an increase in vertebral body height of + 0.3cm (13.6%). During post-operative follow-up, there was a progressive collapse of the vertebral body and pre-surgical height was reached. The factors that most influenced vertebral height restoration were: grade III collapse, intervertebral-vacuum-cleft (IVVC), and use of a flexible trocar before cement augmentation. The factor that negatively influenced vertebral body height restoration was location in the thoracolumbar spine.
