改良切口治疗跟骨关节内骨折

Modified incision for the treatment of intra-articular calcaneal fractures.

目的评价改良切口治疗跟骨关节内骨折的临床疗效。方法采用回顾性研究,我科自2005年1月~2008年12月行跟骨关节内骨折手术75侧,其中41侧使用传统跟骨外侧L形切口,34侧使用改良切口。用SPSS17.0对两者的手术时间、切口长度、切口并发症发生率、B hler角、Gissane角、AOFAS评分做统计学处理。结果两者在手术时间、切口长度、切口并发症发生率P〈0.05,有统计学意义,在B hler角、Gissane角、AOFAS评分P〉0.05,无统计学意义。结论改良切口不但在恢复跟骨解剖结构（B hler角及Gissane角）及关节功能（AOFAS评分）上可以取得和传统切口相同的临床效果,而且可以减少手术时间、切口长度、切口并发症发生率。

Objective To evaluate the clinical effects of modified incision and traditional incision in the treatment of intra-articular calcanea fractures.Methods Seventy-five cases of intra-articular calcaneal fracture were treated with open reduction and interal fixtion by a plate from January 2005 to December 2008.Thirty-four cases were treated with modified incision and 41 cases with traditional incision.Six items of the two groups were evaluated by SPSS17.0： operating time,incision length,incision complication rate,Bhler＇s angle,Gissane＇s angle and AOFAS score.Results There was significant difference in operating time,incision length and incision complication rate between the two groups（P0.05）,but there was no significant difference in Bhler＇s angle,Gissane＇s angle and AOFAS score（P0.05）.Conclusion The modified incision not only can achieve the same clinical effects to the traditional incision in reconstructing the calcaneal anatomic structure and recovering excellent weight-bearing function but also can reduce operating time,incision length and incision complication rate.
