目的 探讨CT平扫+三维重建技 术对骨质疏松性椎体压缩骨折患者椎弓 根宽度变化的评估作用。方法 收集我院 骨科2013年4月至2016年4月所收治的骨折 患者资料进行回顾性分析。骨质疏松性 椎体压缩骨折患者(n=58)纳入A组，胸腰 椎骨折患者(n=46)纳入B组。比较脊椎两 侧POW值及A组与B组脊椎POW值，计算A组 与B组患者的椎弓根细小发生率。结果 58 例患者脊椎两侧POW测量值的差异均无统 计学意义(P＞0.05)。A组T11-L3的POW均高 于B组，差异有统计学意义(P﹤0.05)。L4 与L5的POW与B组之间则无统计学意义(P＞ 0.05)。结论 应用CT平扫+三维重建技术 对骨质疏松性椎体压缩骨折患者进行检查 可有效测量患者椎弓根宽度，从而评估患 者经皮椎体成形术穿刺及椎弓根置钉的可 行性，为手术提供指导。

Objective To explore evaluation function of CT scan and three-dimensional reconstruction technique in the changes of width of pedicle in patients with osteoporotic vertebral compression fractures. Methods A retrospective analysis of clinical data was carried out in fracture patients treated in department of orthopedics of our hospital from April 2013 to April 2016. Patients with osteoporotic vertebral compression fractures (n=58) were divided into group A, patients with thoracolumbar fracture were divided into group B (n=46). POW value in two sides of vertebrae, POW value in vertebrae in group A and group B were compared, incidence of tiny vertebral pedicle in group A and group B were calculated. Results There was no significant difference in POW measured value in two sides of vertebrae in 58 patients (P>0.05). POW in T11-L3 in group A were significantly higher than group B (P<0.05). There was no significant difference in POW in L4 and L5 compared with group B (P>0.05). Conclusion Application of CT scan and threedimensional reconstruction technique can measure patients' width of pedicle effectively in patients with osteoporotic vertebral compression fractures, thus evaluating feasibility of percutaneous vertebroplasty and pedicle for screw placement, and provide direction for operation.
