Abstract Background: When vertebroplasty is used to treat Kummell disease with bone deficiency at vertebral anterior border, bone cement displacement often occurs intraoperative or postoperative. We designed and used a new bone cement screw system to avoid the serious complication. The purpose of this study is to evaluate the safety and effectiveness of this novel operation method through more than 3 years of follow-up. Methods: From January 2012 to August 2016, 27 patients suffering from single-segment Kummell disease with bone deficiency at vertebral anterior border were treated by vertebroplasty combined with novel bone cement screw. Bone cement is released into the diseased vertebrae through screw to fully fill the intravertebral vacuum cleft. Screw fixation of bone cement can avoid intraoperative or postoperative displacement. All patients were operated by unilateral technique, only one screw was implanted for each patient. The clinical efficacy was evaluated using Odom’s criteria and statistical analysis based on the results of vertebral body index (VBI), vertebral body angle (VBA), bisegmental Cobb angle (BCA), visual analogue scale (VAS), oswestry disability index (ODI), and the MOS 36-item short from health survey (SF-36). Results: The operation was completed successfully in 27 cases. The average operation time was 49.63±10.82 min, and the average volume of cement injected was 4.70±0.87 ml. The patients’ preoperative VBI, VBA, BCA, VAS and ODI scores were 43.11±5.94, 21.04±2.55, 45.00±6.26, 7.59±0.84, and 79.85±7.58, respectively. The postoperative measurements were 78.70±2.55, 12.70±2.11, 26.11±4.73, 3.22±0.93 and 50.04±9.28. At the last follow-up, the measurements were 78.04±2.30, 13.15±2.38, 27.07±4.87, 2.04±0.65, and 22.85±5.06, respectively. There was significant difference between the preoperative and postoperative data, as well as the preoperative and the last follow-up data (P<0.05). Compared the results of SF-36 preoperative and at the last follow-up, there were significant differences in physical function, role-physical, body pain, vitality, and social function these 5 items (P<0.05). However, there were no significant differences in general health, emotional function and mental health. Finally, 26 patients (96.3%) had good to excellent clinical outcomes according to Odom's criteria. Conclusions: This 3-year follow-up study shows that the novel bone cement screw system combined with vertebroplasty has a good short and medium-term therapeutic effect on patients with Kummell disease and bone deficiency at vertebral anterior border, while its long-term efficacy is subject to further studies.

Abstract Background: To analyze the effect of different types of bone cement distribution after percutaneous vertebroplasty (PVP) in patients with osteoporotic vertebral compression fracture (OVCF). Methods: 137 patients with single level OVCF who underwent PVP were retrospectively analyzed. The patients were divided into two groups according to bone cement distribution. Group A: bone cement contacted both upper and lower endplates; Group B: bone cement missed at least one endplate. Group B was divided into 3 subgroups. Group B1: bone cement only contacted the upper endplates; Group B2: bone cement only contacted the lower endplates; Group B3: bone cement only located in the middle of vertebral body. The visual analogue scale (VAS) score at 24 hours post operation and last follow-up, anterior vertebral height restoration ratio (AVHRR), anterior vertebral height loss ratio (AVHLR), local kyphotic angle change and vertebral body recompression rate were compared. Results: 24 hours post operation, the pain of all groups were significantly improved. The average follow-up time was 15.3 ± 6.3 (6-24) months. At last follow-up, the VAS score of group A was lower than that of group B. There were 14 cases (10.2%) of adjacent vertebral fracture, 5 cases (8.6%) in group A and 9 cases (11.4%) in group B. There were 9 cases (6.6%) of cement leakage, 4 cases (6.9%) in group A and 5 cases (6.3%) in group B. At last follow-up, there were 16 cases (11.7%) of vertebral body recompression, including 3 cases (5.2%) in group A and 13 cases (16.5%) in group B. There was no significant difference in AVHRR between two groups. Local kyphotic angle change was significant larger in group B. At last follow-up, AVHLR in group B was higher than that in group A. In subgroup analysis, there was no significant difference in VAS score, local kyphotic angle change, vertebral recompression rate, AVHRR or AVHLR. Conclusions: If the bone cement fully contacted both the upper and lower endplates, it can better restore the strength of the vertebral body and maintain the height of the vertebral body, reduce the risk of the vertebral body recompression and long-term pain.

Abstract Background In recent years, percutaneous vertebroplasty (PVP) has provided a new option for the treatment of Kümmell’s disease (KD). The purpose of this study is to study the differences in clinical characteristics, clinical efficacy and related complications between two types of bone cement distribution patterns in the PVP treatment of KD. Methods Retrospective analysis from January 2016 to February 2018 showed that 63 patients with KD who received PVP treatment were included in the study. According to X-ray distribution modes of bone cement after treatment, all patients were divided into blocky group (30 cases ) and spongy group (33 cases). Clinical features and disease severity Preoperatively of the two groups, and clinical efficacy and related complications postoperatively were compared between the two groups. Results There was no significant difference in gender, injured segment, VAS and ODI preoperatively between the two groups (all P > 0.05). The duration of disease, age, Cobb angle and vertebral compression rate preoperatively were significantly higher in the blocky group than in the spongy group (P < 0.05, respectively). The height of vertebral anterior margin and BMD were significantly lower in the blocky group than in the spongy group (P < 0.05, respectively). The two groups were followed for at least 24 months. There were no statistically differences in the follow-up time, operation time, intraoperative blood loss, number of fluoroscopy, bone cement leakage and adjacent vertebral fracture between the two groups (all P > 0.05). The amount of bone cement injected into the blocky group was significantly higher than that of the spongy group (P = 0.000). VAS score and ODI postoperatively of the two groups were significantly reduced at 1 day, 1 year and the last follow-up (all P = 0.000), and were maintained at the last follow-up. VAS score and ODI postoperatively decreased significantly in the spongy group compared with the blocky group (P = 0.000). The correction degrees of kyphosis and vertebral compression postoperatively in the two groups were significantly corrected, but gradually decreased over time (P < 0.05), and these correction degrees of the blocky group was significantly higher than that of the spongy group and the postoperative loss was also more serious. Conclusions The treatment of KD by PVP can effectively relieve pain, improve function, restore vertebral height and correct kyphosis. The disease in the blocky group was more serious than that in the spongy group. The amount of bone cement, correction degrees of postoperative kyphosis and vertebral compression were significantly higher in the blocky group than in the spongy group, but the postoperative loss was also more serious in the blocky group. However, for pain relief and functional recovery, the spongy group was superior to the blocky group. Therefore, the spongy distribution pattern should be formed during the injection of bone cement to obtain better therapeutic effect.

Abstract Background: Percutaneous vertebroplasty (PVP) has been demonstrated to be effective in the treatment of acute osteoporotic vertebral fracture (AOVF). However, bilateral puncture takes more time to accept more X-ray irradiation; some scholars apply unilateral puncture PVP, but the cement cannot be symmetrically distributed in the vertebral body, so we use a flexible cement injector that undergoes PVP through the unilateral pedicle puncture. This research aims to compare the clinical results of PVP for AOVF with unilateral pedicle puncture using a straight bone cement injector and a bendable cement injector, determine the value of a bendable cement injector.Methods: We undertook a retrospective analysis of patients with thoracic and lumbar compression fracture treated with unilateral pedicle puncture Percutaneous vertebroplasty from our institution from June 2013 to July 2015. Operation time, radiation exposure, bone cement injection amount, and the incidence of bone cement leakage were recorded on presentation, the cement leakage was measured by x-ray and computed tomography scan. The patients were followed up postoperatively and were assessed mainly with regard to clinical and radiological outcomes.Results: There was no significant difference in the operation time, radiation exposure time and incidence of bone cement leakage between the two groups. There was significant difference in the amount of bone cement injection and the difference between the two groups. there were no significant differences in VAS and the relative height of the vertebral body and local Cobb angle and QUALEFFO between 2 groups at 1 week after PVP, only significant difference was observed between 12 months after operation.Conclusions: Application of flexible cement injector is safe and feasible,Compared with the application of straight bone cement injector, without prolonging the operative time, radiation exposure time and the incidence of bone cement leakage, it has the advantages of good long-term effect and low incidence of vertebral fracture recurrence.

Abstract Background Percutaneous vertebroplasty (PVP) and kyphoplasty (PKP) have been widely used to treat neurologically intact osteoporotic Kümmell’s disease (KD), but it is still unclear which treatment is more advantageous. Our study aimed to compare and investigate the safety and clinical efficacy of PVP and PKP in the treatment of KD. Methods The relevant data that 64 patients of neurologically intact osteoporotic KD receiving PVP (30 patients) or PKP (34 patients) were analyzed. Surgical time, operation costs, intraoperative blood loss, volume of bone cement injection, and fluoroscopy times were compared. Occurrence of cement leakage, transient fever and re-fracture were recorded. Universal indicators of visual analogue scale (VAS) and Oswestry disability index (ODI) were evaluated separately before surgery and at 1 day, 6 months, 1 year, 2 years and the final follow-up after operation. The height of anterior edge of the affected vertebra and the Cobb’s angle were assessed by imaging. Results All patients were followed up for at least 24 months. The volume of bone cement injection, intraoperative blood loss, occurrence of bone cement leakage, transient fever and re-fracture between two groups showed no significant difference. The surgical time, the operation cost and fluoroscopy times of the PKP group was significantly higher than that of the PVP group. The post-operative VAS, ODI scores, the height of the anterior edge of the injured vertebrae and kyphosis deformity were significantly improved in both groups compared with the pre-operation. The improvement of vertebral height and kyphosis deformity in PKP group was significantly better than that in the PVP group at every same time point during the follow-up periods, but the VAS and ODI scores between the two groups showed no significant difference. Conclusion PVP and PKP can both significantly alleviate the pain of patients with KD and obtain good clinical efficacy and safety. By contrast, PKP can achieve better imaging height and kyphosis correction, while PVP has the advantages of shorter operation time, less radiation volume and operation cost.
