Abstract
<h3>To the Editor.—</h3> Recent letters have documented multiple hazards of break dancing,<sup>1-4</sup>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.<sup>5</sup>These humeral fractures may occur at any age until epiphyseal closure,<sup>5,6</sup>and causes include a direct blow to the arm or a fall onto an outstretched arm.<sup>5</sup>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.
