摘　　要：目的探讨分析桡骨远端骨折术后合并拇长伸肌腱断裂的相关病因。方法收集2005—2015年桡骨远端骨折术后合并拇长伸肌腱断裂患者5例,其中男2例,女3例。5例患者均为摔伤,且为闭合性骨折。均于入院3日内行掌侧入路切开复位内固定术。术后恢复期出现拇指背伸障碍,分别行对应治疗。总结患者的诊疗经过、手术过程、术中所见及术后随诊情况,分析造成桡骨远端骨折术后发生拇长伸肌腱断裂的原因。结果术后第5个月所有患者拇指背伸功能均满意。5例桡骨远端骨折术后拇长伸肌腱断裂患者的病因分别为:1例因血运因素造成,2例患者因桡骨远端特殊解剖因素造成,1例患者因手术内固定物因素造成,1例患者因疾病、年龄等综合因素造成。结论造成桡骨远端骨折术后合并拇长伸肌腱断裂的病因有:血运因素、解剖因素、内固定物因素、年龄因素、疾病因素等,也可能是多因素共同作用所致。Objective To investigate the pathogenesis of distal radius fractures complication with postoperative extensor pollicis longus tendon rupture. Methods Collected 5 cases of distal radius fractures complicated with postoperative long thumb extensor tendon rupture patients who had been treated in our hospital from 2005 to 2015,among them,2 males,3 females. All of the 5 cases were closed fractures and falls,conducted volar open reduction and internal fixation within3 days on admission. In the postoperative recovery period,there was a thumb extension disorder,carried out the corresponding treatment respectively. Analysis of the patients＇ treatmeent,surgical rocedures,intraoperative and postoperative follow- up,analysis of the causes of distal radius fracture postoperative extensor pollicis longus tendon rupture. Results After 5 months of the operation,all of the patients were satisfied with the thumb back stretch function. The etiology of these 5 patients who have distal radius fracture with extensor pollicis longus tendon rupture were respectively as follows：1 case was caused by blood supply factors,2 patients were considered as special anatomy factors of distal radius,1 patient was caused by the factors of internal fixation,1 patient because of disease,age,and other comprehensive factors.Conclusion The causes of distal radius fracture with postoperative extensor pollicis longus tendon rupture： blood factors,anatomic factors,internal fixation factors,age factors,disease factors,and also may be caused by different factors at the same time.
