Abstract

Clavicle fracture and acromioclavicular joint (ACJ) dislocation are common injuries in the shoulder; of these, clavicle fracture accounts for approximately 2.6% to 4% of systemic fractures and 44% of shoulder trauma, and ACJ dislocation accounts approximately 9% of shoulder trauma. However, a combined injury involving a fracture of the middle third of the clavicle and dislocation of the ACJ is quite uncommon. Herein, we report a case of a young male recreational baseball player with simultaneous ipsilateral mid-clavicle fractures and unilateral dislocation of the ACJ. The deduction of the mechanism behind ACJ dislocation with midshaft clavicle fracture and the surgical treatment employed to manage the injury are described, followed by a discussion.
