陈旧性不稳定型骨质疏松脊柱骨折PVP治疗疗效观察

目的 探讨经皮椎体成形术(PVP)治疗陈旧性不稳定型骨质疏松脊柱骨折的临床疗效.方法 根据影像学将20例骨质疏松陈旧性单椎体骨折分为稳定型、不稳定型两组,每组10例,均应用PVP治疗.观察两组患者术前30 min及术后6h、3d、30 d弯腰活动时数字模拟评分(VAS),比较术前、术后伤椎节段站立位与平卧位X线片椎体前缘高度水平.结果 术前30min弯腰时两组患者的VAS评分比较差异有统计学意义(P＜0.05).与术前30 min比较,两组患者术后各观测点VAS评分明显降低,差异有统计学意义(P＜0.05).术后6h、3d、30 d弯腰时两组VAS评分比较,差异无统计学意义(P＞0.05).稳定型组术前、术后椎体前缘高度比较差异无统计学意义(P＞0.05);不稳定型组术后站立位、平卧位椎体前缘高度较术前明显改变,差异有统计学意义(P＜0.05).结论 不稳定型骨质疏松脊柱骨折术前疼痛较稳定型明显,但PVP治疗后二者效果类似;不稳定型骨质疏松脊柱骨折PVP术后高度可得到一定的恢复.

Observation on clinical effect of percutaneous vertebroplasty for treating old unstable osteoporotic vertebral fracture

Objective To explore the clinical effect of percutaneous vertebroplasty (PVP) in the treatment of old unstable osteoporotic vertebral fracture.Methods Twenty cases of old unstable osteoporotic single vertebral body fracture were divided into the stable group and unstable group according to the imaging results,10 cases in each group.PVP was performed in all 20 cases.The VAS scores of waist bending activity at preoperative 30 min,postoperative 6 h,3,30 d were observed.The changes of anterior edge height of spinal body in the injured vertebral segment of erect position and horizontal position were compared before and after operation.Results The VAS score of waist bending at preoperative 30 min had statistical difference between the two groups (P＜0.05).Compared with at preoperative 30 min,the VAS scores at postoperative observation points in the two groups were significantly decreased with statistical difference (P＜0.05).The VAS scores at postoperative 6 h,3,30 d had no statistical difference between the two groups(P＞0.05).The changes of posterior edge height of spinal body in the stable groups had no statistical difference before and after operation (P＞0.05);the anterior edge height of spinal body after treatment in the unstable group were significantly changed compared with before operation,and the difference was statistically significant(P＜0.05).Conclusion Preoperative pain in the patients with unstable osteoporotic vertebral fracture is more obvious than that in the patients with stable osteoporotic vertebral fracture.But all have similar effect after PVP therapy;the postoperative height in unstable osteoporotic vertebral fracture can obtain a certain recovery after PVP.
