Application of acromioclavicular crook plate in treatment of acromioclavicular joint dislocation and distal clavicular fracture in 38 patients / 中华创伤杂志

ABSTRACT

Objective To evaluate the results of acromioclavicukr crook plate in treatment of acromioclavicular joint dislocation and distal clavicular fracture and discuss causes for complications and preventive measures.Methods From September 2003 to April 2007,open reduction and acromiocla vicular crook plate fixation was done on 38 patients with acromioclavicular joint dislocation and distal clavicular fracture including 17 with acromioclavicular dislocation and 12 with distal clavicle fractures.Postoperative rehabilitation began early.Results Of all,27 patients were followed up for mean 21 months (3-37 months) and obtained bone healing.The internal fixation was removed at 6-8 months postoperatively and the outcome was evaluated with Karlsson rating system,which showed 22 patients at grade A,four at grade B and one at grade C.There was no dislocation or fracture after the internal fixation was removed ranging.Three patients with limited abduct motion <90° during certain movements got better after plate removal.One patient had acromio clavicular erosion.Conclusions The application of acromioclavicular crook plate provides accurate anatomical reduction and early rehabilitation and enables fast functional recovery.Technically,the implant needs to be used precisely.It is better to get appropriate early exercise and remove plate as early as possible.
