Abstract:
STUDY DESIGN: A retrospective study. OBJECTIVES: To assess radiological follow-up results, including progression of bone cement augmented vertebrae, of patients who underwent percutaneous vertebroplasty (PVP). SUMMARY OF LITERATURE REVIEW: There are few studies of radiological follow-up results that include progression of bone cement augmented vertebrae after PVP, regardless of good clinical results. MATERIALS AND METHODS: Between January 2000 and August 2007, 253 patients were treated with PVP for osteoporotic compression fracture. Among them, 81 patients died during follow-up and 101 patients (157 vertebrae) were available for follow-up over 7 years. We analyzed the radiologic outcomes, focusing on augmented bone cement feature and progressive change with adjacent vertebrae. RESULTS: The mean follow-up period was 7.9 years. Anterior body height in the last follow-up was improved about 0.3 mm compared with the preprocedural value, but this improvement was not statistically significant. The focal kyphotic angle was reduced from 12.3° at the preprocedural state to 11.7° at the postprocedural state but this change was also not statistically significant (p>0.05). Out of the 101 cases, we observed 7 cases of radiolucent line with decreased bone density in the adjacent area of bone cement and 5 cases of bone cement cracks accompanied with vertebral collapse were observed. Eleven patients (10.8%) had a solid spontaneous fusion, and 8 patients (7.9%) had partially fused with adjacent vertebrae. CONCLUSIONS: The bone cement augmented vertebrae showed stable radiologic progression without significant changes in vertebral height or kyphotic angle. After percutaneous vertebroplasty, unpredictable spontaneous fusion with proximal adjacent vertebrae developed at a higher rate than 10% rate.
