【摘要】 目的比较经伤椎置钉与传统跨伤椎内固定治疗胸腰椎骨折的临床疗效。方法对32例胸腰椎骨折患者,其中17例采用经伤椎椎弓根置钉内固定(A组),15例采用传统的跨伤椎内固定(B组),两组均采用常规植骨融合。比较两组手术时间、术中出血量、伤椎高度和后凸畸形(Cobb角)的纠正与随访丢失、术后下腰痛的Denis评分比较。结果所有患者术后均获随访,随访时间为12~19个月。两组患者在年龄、性别、涉及椎体、术前伤椎高度和Cobb角差异、手术时间、术中出血量的差异无统计学意义(P>0.05);两组术后伤椎高度、Cobb角恢复,术后远期伤椎高度、Cobb角丢失程度,Denis评分等差异有统计学意义(P<0.05)。结论胸腰椎骨折经伤椎置钉可有效减少术后后凸畸形纠正的丢失。更多还原

【Abstract】 Objective To compare the clinic therapeutic effects between transpedicular screw fixation and beyond-injured-vertebral internal fixation over fracture of thracolumbar vertebra. Methods Of 32 thracolumbar vertebra fracture patients, 17 cases were treated with transpedicular screw fixation(group A), and 15 cases were treated with traditional beyond-injured-vertebral internal fixation(group B). Both groups adopted the normal bone graft fusion. Two groups were compared in terms of surgical time, surgical blood loss and Cobb’s angle,fracture vertebral body height, Denis scores. Results A clinic follow-up was carried out for 12 ~ 19 months with the outcome that no significant differences were found in terms of age, gender, vertebral body concerned, pre-surgery injured vertebral body height, Cobb’s angle,surgical time, surgical blood loss(P >0.05), while significant differences were discovered in post-surgery injured vertebral body height,Cobb’s angle recovery, and post surgery long-time injured vertebral body height, Cobb’s angle loss, Denis scores(P <0.05) Conclusions As a cure for fracture of thracolumbar vertebra, transpedicular screw fixation proves more effective than traditional beyond-injured-vertebral internal fixation in terms of rebuilding of injured vertebral height, especially the correction of kyphosis.更多还原
