目的:探讨椎体成形术结合术前复位治疗骨质疏松性椎体压缩楔形骨折可行性及应用价值。方法:采用椎体成形术结合术前复位治疗骨质疏松性椎体压缩楔形骨折20例,并与同期20例经皮kyphon球囊扩张后凸成形术的患者比较手术前后的VAS评分,伤椎椎体前中高度压缩率,后凸角度以及两组伤椎椎体前中高度恢复率。结果:所有患者的术后椎体前中高度压缩率、后凸角度及VAS评分指数较术前均有显著的改善(P<0.05);同时两组组间的伤椎前中高度恢复率进行比较(P<0.05),差异有统计学意义。结论:椎体成形术结合术前复位与球囊扩张后凸成形术都能有效的恢复伤椎高度及后凸角,但前者在恢复伤椎椎体前缘高度上优于后者,在恢复伤椎的中间高度上弱于后者。
Objective: To investigate the feasibility and application of vertebroplasty combined with preoperative reduction in the treatment of osteoporotic vertebral compression wedge fractures. Methods: 20 cases of osteoporotic vertebral compression wedge fractures were treated with vertebroplasty combined with preoperative reduction. Compared with 20 cases of percutaneous kyphon balloon kyphoplasty during the same period, the VAS score, Before and after compression of the anterior vertebral body height, kyphosis angle and the anterior and middle vertebral body height recovery rate of two groups. Results: The preoperative mid-height compression ratio, kyphosis angle and VAS score index of all patients were significantly improved compared with that before operation (P <0.05). At the same time, the anterior and middle vertebral height recovery rate (P <0.05), the difference was statistically significant. CONCLUSION: Vertebroplasty combined with preoperative reduction and balloon dilation kyphoplasty can effectively restore the vertebral height and kyphotic angle, but the former is superior to the latter in restoring the anterior vertebral height of the injured vertebral body. The injured vertebra is weaker than the latter in the middle.
