Closed reduction vertebroplasty for the treatment of osteoporotic vertebral compression fractures. Technical note.
The purpose of this study was to determine the efficacy and feasibility of closed reduction vertebroplasty for the treatment of osteoporotic vertebral compression fractures. Two hundred consecutive patients (183 women and 17 men) with single-level osteoporotic vertebral compression fracture were included in this study. After induction of general anesthesia, the patient was placed prone on an operating table. Closed reduction of the fractured and kyphotic spine was achieved by extending the table to restore the kyphotic angle and vertebral body (VB) height. Percutaneous vertebroplasty was then performed to treat the fractured vertebra. The results were quantitatively evaluated, according to the concept of estimated VB height. The anterior, middle, and posterior VB heights of the fractured vertebra were measured preoperatively and immediately after surgery by studying plain standing lateral radiographs. In 162 (81%) of the compression fractures the anterior VB height was restored (57.1 +/- 24.8% of lost anterior VB height); in 152 (76%) of the compression fractures the middle VB height was restored (61.4 +/- 20.6% of lost middle VB height); and in 52 (26%) of the compression fractures the posterior VB height was restored (51.3 +/- 23.1% of lost posterior VB height). In 141 (71.5%) of the compression fractures kyphosis was corrected by 12.5 +/- 3.8 degrees [mean 61.6 +/- 23.7%]). Closed reduction vertebroplasty is an efficacious and simple method in the treatment of osteoporotic vertebral compression fracture and was able to restore the VB height and kyphotic angle in postions of fractured vertebrae. Its associated, long-term effects on treated vertebrae, however, need further evaluation.
