Abstract
Objectives
The purpose of this study was to assess the clinical efficacy and long term results of patients undergoing percutaneous vertebroplasty, with bone cement, for osteoporotic compression fractures.
Summary of Literature Review
Percutaneous vertebroplasty is an effective surgical method for the treatment of osteoporotic compression fracture.
Materials and Methods
Among 82 patients who underwent percutaneous vertebroplasty, with bone cement, between February 2005 and February 2008, 54 patients who were followed-up for more than 4 years were selected. We compared the postoperative clinical and radiological findings immediately and at 1, 2, and 4 year followup. Clinical findings were evaluated using the Visual analogue scale (VAS) score. Radiologically, height of the vertebral body and adjacent vertebral body fracture were also assessed.
Results
Clinical outcome by mean VAS score revealed a change from 5.9 to 3.8 points preoperatively. The mean VAS scores were 3.4, 3.5 and 3.7 at 1, 2, 4 year followup, retrospectively. The compression rate of the vertebral body on plain radiographs was 30.8% preoperatively, 22.4% immediately after the operation, 23.2% at 1 year followup, 26.9% at 2 year followup, and 29.7% at 4 year followup. A new adjacent vertebral body fracture was noted in 7 patients at 1 year followup and 3 patients at 2 and 4 year followup, respectively.
Conclusions
Percutaneous vertebroplasty is a valuable method for the treatment of osteoporotic compression fractures, providing immediate pain relief as well as long term pain relief. However, percutaneous vertebroplasty gave unsatisfactory report about height of the vertebral body and adjacent vertebral body fracture.
