To the Editor.—  Recent letters have documented multiple hazards of break dancing,1-4 which include masking of testicular torsion, cervical subluxation and dislocation, flank hematoma, clavicle and forearm fractures, torn or sprained ligaments, and alopecia. Two 14-year-old male adolescents were seen in the emergency department on the same day for an uncommon Salter type I fracture of the proximal humerus incurred while break dancing (Figure).Fractures of the proximal humeral epiphyseal plate represent only 3% of all physeal fractures.5 These humeral fractures may occur at any age until epiphyseal closure,5,6 and causes include a direct blow to the arm or a fall onto an outstretched arm.5 Both our patients sustained a fracture while performing a maneuver that involved supporting all or most of the body weight on one hand for a short time during a rapid series of maneuvers.
