Unusual Case of a Traumatic Proximal Humeral Physeal Fracture in an Adolescent.

Shoulder injuries, specifically proximal humeral fractures, are uncommon in skeletally immature patients. The anatomic characteristics of the humerus are determined by its ossification development, which is quite particular in the proximal segment where four principal segments have been outlined as fracture components in adults. Hereby, we present the case of an 18-year-old female who suffered a traffic accident that elicited a proximal humeral injury through the physeal line of the anatomical neck, as well as the treatment given and her clinical outcome with an effort to highlight the complexity of the diagnosis and management of this injury given the transitional bone age.
