骨囊袋填充椎体成形术对骨质疏松性椎体压缩骨折患者功能及椎体高度的影响

Effect of Bone Capsule Filling Vertebroplasty on Function and Vertebral Height of Patients with Osteoporotic Vertebral Compression Fracture

目的 探讨骨质疏松性椎体压缩骨折患者采用骨囊袋填充椎体成形术对其功能及椎体高度的影响。方法 将该院2015年1月—2018年3月收治的84例骨质疏松性椎体压缩骨折患者根据手术方案不同分组,观察组41例行骨囊袋填充椎体成形术,对照组43例行经皮椎体后凸成形术,比较两组功能、椎体高度恢复情况及并发症发生情况。结果 两组患者术前的Oswestry功能障碍指数(ODI)差异无统计学意义(t=0.479,P=0.632),观察组术后3个月的ODI评分分别为(27.52±2.86)分,明显较对照组(32.71±3.09)分低(t=7.978,P=0.000);两组术前的伤椎前缘高度、中部高度、Cobb’s角差异无统计学意义(t=0.203、0.122、0.269,P=0.839、0.903、0.788),观察组术后3个月分别为(78.96±2.37)mm、(83.42±3.58)mm、(10.21±1.28)°,均优于对照组术后3个月(73.62±2.05)mm、(78.27±2.37)mm、(12.19±0.83)°(t=10.911、7.680、8.310,P=0.000、0.000、0.000);观察组骨水泥渗漏发生率为2.44%,明显低于对照组16.28%(χ2=4.665,P=0.031)。结论 骨囊袋填充椎体成形术治疗骨质疏松性椎体压缩骨折效果优于经皮椎体后凸成形术,有利于患者功能及椎体高度恢复,也能减少骨水泥渗漏发生,值得推广。

Objective To investigate the effect of bone capsule filling vertebroplasty on the function and vertebral height of patients with osteoporotic vertebral compression fracture. Methods A total of 84 patients with osteoporotic vertebral compression fractures admitted to our hospital from January 2015 to March 2018 were grouped according to the surgical plan. The 41 patients in the observation group underwent capsular bag filling vertebroplasty, and 43 patients in the control group underwent percutaneous kyphoplasty. The functions, vertebral height recovery and complications were compared between the two groups. Results There was no significant difference in Oswestry dysfunction index (ODI) between the two groups (t=0.479, P=0.632). The ODI scores of the observation group at 3 months after operation were (27.52±2.86)points which was significantly lower than that of the control group (32.71±3.09)points (t=7.978,P=0.000). Three months after operation, the preoperative cervical height, central height, and Cobb’s angle of the observation group were (78.96±2.37) mm,(83.42±3.58) mm,(10.21±1.28)°, which was superior to the control group (73.62±2.05) mm,(78.27±2.37) mm,(12.19±0.83)°(t=10.911,7.680,8.310, P=0.000,0.000,0.000)(t=0.203,0.122,0.269, P=0.839,0.903,0.788). Before the operation, there were no significant difference in these data between the two groups. The incidence of bone cement leakage in the observation group was 2.44%, which was significantly lower than that in the control group 16.28%,the difference w asstatistically significant(χ^2=4.665, P=0.031). Conclusion Bone capsular bag filling vertebroplasty is superior to percutaneous kyphoplasty in the treatment of osteoporotic vertebral compression fracture, which is beneficial to the recovery of patient function and vertebral height, and can also reduce the occurrence of bone cement leakage.
