BACKGROUND:: Percutaneous vertebroplasty (PVP) has been demonstrated to be effective in the treatment of acute osteoporotic vertebral fracture (AOVF). However, the matter of which surgical approach should be selected remains controversial. This research aims to compare the clinical results of unilateral and bilateral PVP for AOVF.
METHODS:: From January 2008 to December 2011, 68 patients with AOVF were randomly assigned to the unilateral puncture group (n=36) or the bilateral group (n=32). These patients underwent percutaneous injection of poly-methyl methacrylate into posterior pedicle by the unilateral or bilateral puncture approach. Visual analogue scale (VAS) and the Quality of Life Questionnaire of the European Foundation for Osteoporosis (QUALEFFO) were recorded on presentation, at 1 week, 3, 6 and 12 months after operation. The cement leakage was measured by X-radiograph and computed tomography scan.
RESULTS:: Follow-up data showed there were no significant differences in VAS and QUALEFFO between two groups at 1 week after PVP and only significant difference was observed between two groups at 3, 6 and 12 months after operation. The cement leakage was 52.7% in the unilateral puncture group and 28.1% in the bilateral group.
CONCLUSION:: Compared with unilateral puncture, use of bilateral approach during PVP may result in more superior long-term outcomes and less cement leakage for patients with AOVF.
