Abstract
BACKGROUND:Vertebroplasty with bone cement injection in treatment of osteoporotic vertebral compression fractures has a positive clinical outcome, but there is a big controversy on the optimal timing of surgery. OBJECTIVE:To analyze the effect of fracture time on bone cement dispersion within pathologic vertebrae in vertebroplasty treatment. METHODS: Totaly 160 elderly patients with osteoporotic vertebral compression fracture were included, and al were treated with vertebroplasty with high viscosity bone cement injection. According to the duration from fracture to surgery, patients were divided into three groups: fresh fracture group (< 3 weeks), subacute group (3-6 weeks) and old group (> 6 weeks). The bone cement distribution features, diffusion and leakage within the pathologic vertebrae were analyzed by three-dimensional CT image and X-rays. RESULTS AND CONCLUSION:The bone cement dispersion volume was ranked as fresh group > subacute group > old group, and there was significant difference between groups (P < 0.05). Bone cement dispersion characteristics of each group were uniform distribution with cement-based lumpy shape. The vast majority of bone cement al can disperse to exceed vertebral midline, reaching the upper and lower lamina to a greater degree. Bone cement dispersion coefficient within the pathologic vertebrae of patients in each group was 关键词
