跟骨解剖型钢板与锁定型钢板治疗跟骨关节内粉碎性骨折的比较

Comparative Study of the Curative Effect of Anatomical Plate and Locking Plate in Treating Calcaneous Intraarticular Fracture

目的对比跟骨的解剖型钢板与锁定型钢板在治疗跟骨关节内骨折的疗效.方法 67例跟骨关节内骨折患者.随机分为解剖型钢板组(n=33)和锁定型钢板组(n=34).术后1周与6月,比较2组:(1)Bo..hler角;(2)Gissane角;(3)跟骨长轴长度;(4)跟骨宽度;(5)跟骨丘部高度;(6)Maryland足部评分等.结果术后1周,2组间的Maryland足部评分、跟骨长轴长度、跟骨宽度、Bo..hler角、Gissane角、跟骨宽度和跟骨丘部高度差异无统计学意义(P>0.05);术后36周,2组间的Maryland足部评分、跟骨长轴长度、跟骨宽度、差异无统计学意义(P>0.05);但Bo..hler角、Gissane角、跟骨的宽度和跟骨的丘部高度等指标上,差异有统计学意义(P<0.05).结论术后6月随访中,锁定型钢板组主要解剖测量指标明显优于解剖型钢板治疗组,跟骨锁定型钢板值得临床推广应用.

Objective To compare the curative calcaneous intraarticular fracture. Methods 67 pedants effect of anatomical plate and locking plate in treatment of with calcaneous intraarticular fracture were randomly divided into anatomical plate group （n=33） and locking plate group （n=34） . The Bohler angle, the Gissane angle, the length of calcaneal axis, the width and height of calcaneous and the Maryland grade were compared at 1 week and 6 month after operation. Results （1） week after operation, the Bohler angle, the Gissane angle, the height and width of calcaneous, the length of calcaneal axis, the Maryland grade had no significant difference between 2 groups . 6 months after operation, the Bohler angle, the Gissane angle, the height of ealcaneous had significant differe nee between 2 groups. There was no significant difference in the length of calcaneal axis and the grade of Maryland between 2 groups. Conclusions The locking plate group is better than anatomical plate group in major anatomical measure indicators in 6 months follow up. The therapy of locking plate is worth of clinical promotion.
