Adolescent butterfly swimmer with bilateral subluxing sternoclavicular joints

Sternoclavicular joint subluxation/dislocation injuries in the athlete are uncommon. They can be organised by degree (subluxation, dislocation), timing (acute, chronic, recurrent, congenital), direction (anterior, posterior), and cause (traumatic, atraumatic). The unusual case reported is an adolescent butterfly swimmer with recurrent bilateral sternoclavicular subluxation associated with pain and discomfort. The condition was treated and resolved with conservative management. The diagnosis, investigations, and treatment options are discussed.
