胸腰段脊柱骨折后路短节段固定效果对比分析

目的 采用实验流行病学方法,探讨后路短节段固定治疗胸腰段脊柱骨折的远期生物力学形态,分析融合治疗的远期疗效.方法 选取山东大学齐鲁医院2004年2月- 2006年12月79例单节段胸腰段脊柱骨折患者,以手术方式分为非融合组(42例)和融合组(37例)2组分别进行单纯后路短节段固定治疗和后路短节段固定并行植骨融合治疗,分别于术后1周、术后3个月、术后1年及取出内固定术后3个月对比2组患者伤椎前后缘高度及Cobb角度变化情况.结果 术前非融合组和融合组椎体前后缘高度、Cobb角度异均无统计学意义(P＞0.05)；术后1周、术后3个月2患者间椎体前后缘高度、Cobb角度差异均无统计学意义(P＞0.05)；术后1年2患者间椎体前缘高度、Cobb角度及断钉例数差异均有统计学意义(P＜0.05)；取出内固定术后3个月,非融合组和融合组患者间椎体前缘高度(83.3±5.3;94.2±3.1)、Cobb角度(9.3±5.8;2.4±3.7)差异均有统计学意义(P＜0.05).结论 后路短节段固定并植骨融合治疗胸腰段脊柱骨折的远期疗效明显优于单纯后路短节段固定治疗.

Comparative study of posterior approach short-segmental fixation for thoracolumber spine fracture

Objective To observe the long-term biomechanical conformation after thoracolumber spine fracture cured by posterior approach short-segmental fixation with fusion or non-fusion technique,and to compare long-term clinical outcomes of the two methods. Methods From February 2004 to December 2006,79 patients with one level thoracolumber vertebral fracture(TVF) were treated with two operation methods:posterior approach short-segmental fixation(control group,non-fusion group) and posterior approach short-segmental...
