Atraumatic Acromioclavicular Joint Dislocation: A Case Report Treated with Excision of the Distal Clavicle Margin and Button Slide System with Allograft Tendon Reinforcement at Coracoclavicular and Acromioclavicular Joint.

Although acromioclavicular joint (ACJ) dislocation is a common injury following trauma involving the shoulder, it is rare in the absence of trauma. In this manuscript, we describe a case of ACJ in a 15-year-old girl who presented a painful dislocation with spontaneous shortening of the right acromioclavicular joint that forced her to temporarily abandon her sports career. After failure of conservative physiotherapy treatment, surgical intervention was proposed by performing an arthroscopic-assisted button slide combined with augmented hamstring allograft reconstruction.

Arthroscopic Revision Surgery for Failure of Open Latarjet Technique.

Purpose: To evaluate the efficacy in treating pain, limited range of motion, and continued instability of the Latarjet open technique via the use of arthroscopy.

Methods: A retrospective review of patients who underwent arthroscopic capsule plication after failure of an open Latarjet technique was performed. Revision surgery was indicated in cases of recurrent instability and associated pain.
