Management of Type 3 Acromioclavicular Joint Dislocation : Comparison of Long-Term Functional Results of Two Operative Methods

Abstract EN

Introduction.

Treatment of Rockwood Type 3 Acromioclavicular joint dislocation is controversial.

We compared the long-term functional outcome of early repair of coracoclavicular ligament and internal fixation (Tension Band Wiring) with delayed reconstruction by modified Weaver-Dunn procedure for Type 3 dislocations.

Method.

Retrospective analysis of case records and telephone review to assess the long-term functional outcome by patient satisfaction and Oxford shoulder score.

Results.

We had 18 cases of Type 3 Acromioclavicular dislocations over a period of 10 years.

7 cases had Tension Band Wiring and 11 cases had modified Weaver-Dunn procedure.

Early repair group has higher risk (71%) of post operative complications compared to that of the delayed reconstruction group (9%).

All 5 patients who developed postoperative complications in the early repair group required a second operation for metal work removal.

Long-term functional results of both groups were comparable in terms of Oxford shoulder score and patient satisfaction.

Conclusions.

We recommend modified Weaver-Dunn procedure for failed conservative management of Grade 3 Acromioclavicular joint dislocation for the following reasons (1).

better short-term functional outcome, low risk of complications and hence faster recovery (2).

no need for a second surgery.
