ABSTRACT

BACKGROUND: Percutaneous vertebroplasty (PVP) has been gradually used for osteoporotic vertebral compression fracture (OVCF) treatment, but severe osteoporotic vertebral body compression fractures (sOVCFs) due to the difficulty in performing a puncture and the characteristics of the fractured vertebrae, it has been considered as a contraindication to PVP. The aim of the following study was to evaluate the feasibility of a unilateral, three-dimensional (3D), accurate puncture in percutaneous vertebroplasty (PVP) for a single, severely osteoporotic vertebral body compression fracture (ssOVCFs). MATERIALS AND METHODS: 57 patients received PVP in the current study. Feasibility of a unilateral approach was judged before surgery using the 64-slice helical computed tomography (CT) multiplanar reconstruction technique, a 3D accurate puncture plan was then determined. The skin bone distance, puncture angle and needle insertion depth were recorded during surgery. 2D CT rechecking was performed for any complication at day 1 after operation. Preoperative and postoperative numerical data were compared. RESULTS: The procedure was completed smoothly in all patients. 2D CT scanning at day 1 after operation did not show any puncture related complications. Visual analog scoring (VAS) showed that the score at day 3 after surgery was reduced to 1.7 ± 0.4 (0-2.9 scale) from the preoperative 7.9 ± 2.1 (6.1-9.5 scale). No significant differences in measure numerical data were found before and after the surgery. At 12 months followup three patients presented with nonadjacent level fractures, VAS for other patients were 1.2 ± 0.3 (0-2.1 scale). CONCLUSIONS: Application of CT scanning for a unilateral 3D puncture design helps realize an accurate puncture in PVP. It is a safe and effective method for ssOVCFs treatment.
