This retrospective cohort evaluated surgical treatment of complete (Allman-Tossy Grade III) AC dislocations using a modified Weaver-Dunn technique. It compared outcomes of acute repair (<3 weeks) versus chronic reconstruction (>3 weeks). The question: does delaying surgery penalize the patient?
The clinical decision rule here is timing: if you are going to operate on a Grade III AC dislocation, do it before 3 months, because reconstruction after that window yields significantly worse results. Within the first few weeks the penalty for delay is a trend, not a proven difference, so it is reasonable to trial nonoperative care in ambiguous cases and reserve surgery for failures.
The authors frame their chronic group as nonoperative failures, which reflects real-world practice: most Grade III injuries are managed conservatively first, and surgery is for symptomatic patients such as athletes and laborers.
The technique detail worth carrying to the OR: combine coracoclavicular suture fixation with a minimal distal clavicle resection to prevent late AC arthritis and osteolysis and to give the transferred coracoacromial ligament a healing surface. Remember that isolated distal clavicle resection fails in complete dislocations because it does not address instability.
