To assess the relationship between sagittal collapse, posterior instrumentation failure and the McCormack classification among patients with thoracolumbar burst fractures who had undergone posterior arthrodesis more than one level above and one level below the fracture.
This was a retrospective review based on the medical records and radiographs of 26 patients who underwent operations between January 1990 and December 2006. The parameters assessed were: worsening of kyphosis (Cobb), neurological dysfunction (Frankel) and failure of surgical treatment (implant breakage or loosening).
No relationship was found between sagittal collapse and the scoring in the McCormack classification (r = 0.221; P = 0.322). There was also no relationship between failure of the posterior implant and the scoring in this classification (p = 0.85).
Our findings suggest that this classification is not applicable to patients who underwent arthrodesis more than one level above and one level below the fracture.
评估胸腰椎爆裂骨折患者在骨折节段上下至少各一个节段进行后路融合术后矢状面塌陷、后路内固定失败与麦科马克分类之间的关系。
这是一项基于1990年1月至2006年12月期间接受手术的26例患者的病历和X线片的回顾性研究。评估的参数包括：后凸畸形加重（Cobb角）、神经功能障碍（Frankel分级）和手术治疗失败（内植物断裂或松动）。
矢状面塌陷与麦科马克分类评分之间未发现相关性（r = 0.221；P = 0.322）。后路内植物失败与该分类评分之间也无相关性（P = 0.85）。
我们的研究结果表明，该分类不适用于在骨折节段上下至少各一个节段进行融合术的患者。
