[Arthroscopic surgery of the acromioclavicular joint]

Lesion of the acromioclavicular joint is a usual clinical condition because of it superficial situation. It is often involved in trauma of the shoulder girdle. Moreover, degenerative changes are quite always observed for patients over 40. Distal clavicle resection as a treatment of acromioclavicular joint disease had been first described in 1941. Clinical results in term of mobility and shoulder pain are good and durable in time. Referring to the expansion arthroscopic techniques, distal clavicle resection lead to same middle and long term results as open surgery. Arthroscopic procedures have the theoretical advantages of no deltoid disruption and may help the surgeon to diagnose and treat associated lesions such as rotator cuff ruptures. More recently, arthroscopic surgeries for fresh and/or chronic acromioclavicular disjunctions were proposed. These procedures remain in development and need further evaluations.
