Arthroscopic Distal Clavicle Resection For Isolated Atraumatic Osteolysis in Weight Lifters

Ten consecutive patients with isolated atraumatic osteolysis of the distal clavicle who had failed results with conservative treatment were treated with arthroscopic resection of the involved distal clavicle (average, 4.5 mm). All patients were men with an average age of 30.4 years, had unilateral involvement, and were considered aggressive amateur to elite weight lifters or bodybuilders. Postoperative symptoms consisted of pain at the incision and discomfort from extravasation of the irrigation fluid. At an average followup of 18.7 months, all patients had returned to their sport (average, 3.2 days) and to their preoperative weight training program (average, 9.1 days). They continued to be asymptomatic throughout the follow-up period and were able to increase both their training volume and strength from preoperative levels. Limited arthroscopic resection of the distal clavicle for isolated atraumatic osteolysis is a viable alternative for the weight lifter or bodybuilder. The ability to continue training without significant interruption as well as a more acceptable cosmetic appearance are benefits for these patients. Limited arthroscopic resection of the distal clavicle may be sufficient for this entity in this patient population, rather than the 1 to 2 cm previously reported. A sport-specific functional outcome questionnaire has been developed for this patient population.
