关节镜辅助下踝关节融合术中异体骨植骨的作用

目的探讨关节镜辅助下踝关节融合术中异体骨植骨的效果。方法回顾性分析2006年3月-2011年8月我科行关节镜辅助下踝关节融合术24例,其中采用同种异体骨填充关节间隙13例,未植骨填充11例。手术前后采用疼痛视觉模拟评分（visual analog scale,VAS）和美国足踝关节协会评分系统（American Orthopaedic Foot and Ankle Society,AOFAS）进行评价。结果 24例均获随访。患者步态改善,踝关节疼痛明显缓解。术后1年VAS评分为（1.7±0.5）分,与术前的（7.2±1.2）分比较差异有统计学意义（P〈0.05）;术后1年AOFAS评分为（80.7±5.2）分,与术前的（49.5±9.8）分比较差异有统计学意义（P〈0.05）。植骨组在12周内融合12例,未植骨组在12周内融合8例。结论关节镜辅助下踝关节融合术是踝关节融合的理想方法,术中异体骨植入可以缩短融合所需的时间。

Role of allo-bone graft in arthroscopy-assisted ankle arthrodesis

Objective To study the role of allo-bone graft in arthroscopy-assisted ankle arthrodesis.Methods Twenty-four patients who underwent arthroscopy--assisted ankle arthrodesis in our department from March 2006 to August 2010（13 with allo-bone graft and 11 without allo-bone graft） were retrospectively analyzed.Their ankle pain was scored according to the visual analog scale（VAS） and the American Orthopaedic Foot and Ankle Society（AOFAS） before and after operation.Results The patients were followed up,during which their gait and ankle pain were significantly improved.Their VAS score was significantly lower whereas their AOFAS score was significantly higher 1 year after operation than before operation（1.7±0.5 vs 7.2±1.2,80.7±5.2 vs 49.5± 9.8,P 〈0.05）.The bone tissue was fused in 12 patients with allo-bone graft and in 8 patients without allo-bone graft in 12 weeks after operation.Conclusion Arthroseopy-assisted ankle arthrodesis is an ideal procedure for ankle fusion and allo-bone graft can shorten its fusion time.
