目的探讨骨质疏松性椎体压缩骨折椎体成形术后相邻椎体再骨折的影响因素。方法选取41例2013年10月—2014年9月收治的所有骨质疏松性椎体压缩骨折行双侧椎弓根穿刺椎体后凸成形术治疗的患者,对所有病例于术后1周、3个月、6个月、12个月应用双能X线骨密度仪测定上、下相邻椎体骨密度,对比骨量丢失情况。结果术后12个月内上位椎体骨密度为(1.052±0.088)g/cm2,下位椎体骨密度为(0.901±0.145)g/cm2,差异有统计学意义(P<0.01),术后3个月,上位椎体骨密度较术前减少了13.14%,下位椎体骨密度较术前减少了27.64%,差异有统计学意义(P<0.01)。结论下位椎体较上位椎体骨密度减少明显,术后12个月内,上、下相邻椎体均出现骨量丢失。
Objective To investigate the influencing factors of adjacent vertebral body fractures after vertebroplasty of osteoporotic vertebral compression fractures. Methods Totally 41 patients underwent bilateral pedicle puncture and kyphoplasty for all osteoporotic vertebral compression fractures from October 2013 to September 2014. All cases were treated with 1 week postoperatively, Three months, six months, 12 months using dual-energy X-ray absorptiometry to determine the upper and lower adjacent vertebral body bone mineral density, bone loss comparison. Results The bone density of the upper vertebral body was (1.052 ± 0.088) g / cm2 and the lower vertebral body bone density was (0.901 ± 0.145) g / cm2 within 12 months after operation. The difference was statistically significant (P <0.01) At 3 months, the vertebral bone density in the upper vertebral body decreased by 13.14% compared with that before operation, and the lower vertebral body bone mineral density decreased by 27.64% compared with that before operation. The difference was statistically significant (P <0.01). Conclusion The vertebral lower vertebral body vertebral bone density decreased significantly, within 12 months after operation, the upper and lower adjacent vertebral bone loss occurred.
