[摘要][目的]评价改良Weaver-Dunn技术治疗肩锁关节脱位的临床疗效并与传统方法（包括肩锁钩钢板固定和克氏针钢丝张力带固定）进行比较，以确定其治疗优势。[方法] 对Rockwood分型3型以上肩锁关节脱位或骨折脱位，采用改良Weaver-Dunn技术手术治疗30例，对照分析采用肩锁钩钢板治疗46例，采用克氏针钢丝张力带治疗41例，分别对其手术时间、平均住院日、是否需要二次手术、手术费用及术后肩关节功能进行比较。117例病例均获得了随访,平均随访时间36.5 个月。[结果]改良Weaver-Dunn技术治疗组：一次手术即可完成、无术后复发或再脱位、平均住院日及手术费用均低于传统手术（传统手术常需两次手术），但手术时间长于传统手术，术后肩关节功能采用UCLA肩关节评分系统评价优良率96.6%明显高于对照组（P<0.05），改良Weaver-Dunn技术还可做为传统手术失败的补救手段。[结论]改良Weaver-Dunn技术治疗肩锁关节脱位或骨折脱位是一种理想的方法，与传统手术方法相比具有明显的优势，。宁夏医科大学总医院创伤骨科安维军

[Abstract] [Objective] To evaluate the clinical effect of operation on the acromioclavicular dislocation or fracture-dislocation perfomed by modified Weaver-Dunn procedure,and compaired it with  traditional operation by acromioclavicular hook plate and  K-wire tension-band respectly so as to demonstrate its advantages. [Method] To surgical treat  Rockwood  type Ⅲ acromioclavicular dislocation or fracture-dislocation ,perfomed by modified Weaver-Dunn procedure 30 cases, fixed by acromioclavicular hook plate 46 cases, by K-wire tension-band 41cases.All of the 117cases were followed- up, The  average time was 36.5 months. [Results] The  modified  Weaver-Dunn technique groups: accomplish operation only once time,no postoperation redislocation or recrudesce,the average stay-in hospital time and the cost was lower than the traditional tratement groups,but the operation time was longer.The postoperation shoulder function was evaluated by UCLA scoring system:the excellent and good aws 96.6% , higher than the other groups significantly (P <0.05). The  modified  Weaver-Dunn technique is also a kind of remedy method for the unsuccessful cases that was  treated by the traditional methods. [Conclusion]The modified   Weaver-Dunn techeque is a kind of ideal way to surgical treat acromioclavicular,have more advantages than the traditional methods.
