To describe the arthroscopic partial posterior distal clavicle beveling technique for treatment of chronic nonincarcerated type IV acromioclavicular (AC) separations and report clinical outcomes and return to sport.MethodsAll patients who underwent the arthroscopic partial distal clavicle beveling technique and met eligibility criteria were identified and retrospectively reviewed. Inclusion criteria included the clinical diagnosis of a chronic nonincarcerated type IV AC separation and a minimum follow-up period of 24 months. Subjects completed the American Shoulder Elbow Surgeons shoulder assessment and a study-designed questionnaire. Radiographic images and clinical charts were also reviewed.ResultsThis study identified 15 consecutive patients with 2 lost to follow-up, resulting in inclusion of 13 subjects (9 males and 4 females). Dominant arm was involved in 77% of cases. Mean age at operation was 33.2 years (range, 19-56 years). The mean period between injury and operation was 12.5 months (range, 3-37 months), and follow-up was 48.5 months (range, 24-126 months). The mean preoperative ASES score was 46.6 ± 16.9 (range, 33-68), and the mean postoperative ASES score was 87.3 ± 17.4 (range, 50-100) (P < .0001). All 9 athletes in the study returned to competition with a mean recovery period of 2.3 months (range, 2 weeks to 4 months). Mean timeframe for return to work was 2 weeks (range, 1 day to 2 months). One subject underwent a subsequent coracoclavicular ligament reconstruction for continued pain. The mean satisfaction level was 4.3 out of 5, and 91% would choose to have the surgery again. One subject indicated dissatisfaction with shoulder appearance.ConclusionsThe arthroscopic partial distal clavicle beveling procedure for nonincarcerated type IV AC separations resulted in a significant reduction in pain, improved daily function, and early return to sport.Level of EvidenceLevel IV, therapeutic case series.
