指骨基底髁角在指骨骨折畸形矫形术中的应用

Significance of intercondylar angle （ICA） in management of phalangeal deformity

目的 分析指骨基底髁角在指骨骨折畸形愈合矫形术中的临床应用.方法 2012年2月-2014年1月,通过对21例指骨骨折畸形愈合患者术前畸形角度的测量,再根据指骨侧方成角的方向,选择加上或减去基底髁角度,获得最终的截骨角度.结果 按照上述方法获得的截骨角度进行截骨矫形治疗,全部患指获得良好的矫形效果,术后随访6~18个月,患指的功能及外观均恢复正常,骨折愈合时间6~9个月,无延期愈合或骨不连发生.结论 指骨骨折畸形愈合的截骨矫形术中需要考虑基底髁角的存在,否则导致截骨角度过大或不足,无法达到精确的矫形.

Objective To investigate application of ICA in management of phalangeal deformity. Methods 21 patients with maluninted phalangeal fracture underwent V-shaped osteotomy to correct the deformity. The angle of the V was determined by the angulation of the fracture plus or minus the ICA. Results All patients achieved satisfactory correction both cosmetically and functionally during the follow-up of 6-18 months. Bony union took 6 to 9 months. None of the patients exhibited delayed union or nonunion. Conclusion ICA is ought to be taken into consideration in correction of phalangeal deformity to avoid excessive or insufficient osteotomy.
