目的 探讨改良克氏针张力加压牵引治疗骨性锤状指的临床效果.方法 2010年3月至2012年3月对28例骨性锤状指患者采用克氏针张力牵引的同时结合钢丝交叉加压骨块治疗.结果 本组26例获得随访,2例失访,随访时间为4～18个月,平均9个月,伤口均Ⅰ级愈合,患指远指间(DIP)关节伸屈活动度为0°～70° 7例,0°～60° 15例,0°～55°2例,0°～ 30°1例,关节无活动度1例.26例骨折均骨性愈合,骨折愈合时间平均为2个月,其中2例向背侧移位畸形愈合,1例DIP关节活动度为0°～30°的患者因关节疼痛行DIP关节融合.根据Patel等的锤状指疗效评价标准评定:优7例,良15例,中2例,差2例,优良率达85％.结论 采用改良克氏针张力加压牵引治疗骨性锤状指,应用材料简单,手术操作容易,临床效果满意.“,”Objective To investigate the clinical results of using modified Kirschner wire tension compression traction to treat bony mallet finger.Methods From March 2010 to March 2012,28 cases of bony mallet fingers were treated with Kirschner wire tension traction combined with crisscross wire compression of the fracture fragment.Results Of these patients 26 were follow-up for 4 to 18 months with an average of 9 months,while 2 cases were lost to follow-up.All the wounds healed primarily.Range of motion of the distal interphalangeal joint was 0°to 70° in 7 cases,0°to 60° in 15 cases,0°to 50° in 2 cases,0°to 30° in 1 case,and no joint movement in 1 case.Bone union of the fracture fragment was achieved in these 26 patients.The average fracture healing time was two months.Dorsal displacement malunion occurred in two cases.Fusion of the DIP joint was done due to joint pain in one case that had 0°to 30° range of motion of the DIP joint.According to Patel mallet finger evaluation criteria,the results were excellent in 7 cases,good in 15 cases,fair in 2 cases and poor in 2 cases.The excellent and good rate was 85 ％.Conclusion Modified Kirschner wire tension compression traction technique leads to satisfactory clinical results in the treatment of bony mallet fingers.The materials needed are simple and the procedure is easy.
