目的:研究骨质疏松性压缩骨折经皮椎体成形术椎弓根残留骨水泥评分与术后腰痛的相关性。方法:选取2013年1月—2015年5月行经皮椎体成形术治疗、且术后随访1年均出现不同程度腰痛的骨质疏松性压缩骨折的84例患者为观察对象,根据预后不同分为为预后良好组(A组)和预后不良组(B组),每组42例,对比两组椎弓根残留骨水泥评分差异,并与VAS评分做相关性比较。结果:两组治疗前后VAS评分均有显著差异,A组治疗后VAS评分(2.24±0.78)分,显著低于B组(4.52±0.95)分,(P<0.05);A组椎弓根内、外侧残留骨水泥评分(0.21±0.05)分和(0.25±0.07)分,均显著低于B组(0.38±0.12)分和(0.45±0.16)分,(P<0.05);椎弓根内侧区及外侧区残留骨水泥残留评分与术后腰痛均呈正相关关系(r=0.749,0.761;P=0.000,0.000);A组再骨折发生率(0%)及住院时间(7.62±2.45)d,均显著低于B组(均P<0.05)。结论:骨质疏松性压缩骨折经皮椎体成形术椎弓根残留骨水泥评分与术后腰痛呈正相关关系,应对骨水泥残留物进行清除,从而提高治疗效果,减轻术后腰痛程度。
OBJECTIVE: To study the correlation between postoperative pedicle residual cement and percutaneous vertebroplasty in osteoporotic compression fractures. Methods: From January 2013 to May 2015, 84 patients who underwent percutaneous vertebroplasty and osteoporotic compression fractures with varying degrees of low back pain were followed up for one year after operation. According to the prognosis, For the good prognosis group (group A) and the poor prognosis group (group B), 42 cases in each group were compared between the two groups of pedicle residual cement score differences, and VAS scores do correlation. Results: The VAS scores of two groups were significantly different before and after treatment. The VAS score of group A after treatment was significantly lower than that of group B (2.24 ± 0.78) (P <0.05) (0.21 ± 0.05) and (0.25 ± 0.07) points in the lateral residual cement were significantly lower than those in the B group (0.38 ± 0.12) and (0.45 ± 0.16) points, respectively (P <0.05) There was a positive correlation between residual cement and postoperative low back pain (r = 0.749,0.761; P = 0.000, 0.000) in group A and group B. The incidence of re-fractures in group A (0%) and hospital stay (7.62 ± 2.45) d , All significantly lower than those in group B (all P <0.05). Conclusion: Percutaneous vertebroplasty of vertebral osteoporosis with residual pedicle screw cement score is positively correlated with postoperative low back pain. Cleft cement should be removed to improve the therapeutic effect and relieve postoperative low back pain.
