Lesser Trochanter Avulsion Fracture in an Adolescent after Seizure.

BACKGROUND: Injury secondary to epileptic seizure is widely documented in the literature. In particular, uncontrolled muscular contractions generated during a seizure can lead to a variety of musculoskeletal injuries. CASE REPORT: We present the case of a 16-year-old male who presented on two separate occasions after a tonic-clonic seizure with hip pain, an antalgic gait, and marked discomfort on hip flexion. Radiologic investigation revealed an acute isolated fracture of the lesser trochanters. Such fractures in adolescents are normally secondary to athletic injury and in adults are mainly associated with the presence of metastatic bone disease. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: We present this case with its previously undocumented mechanism to highlight the injury to frontline emergency medical teams, create awareness of its presentation, and to discuss its potential mechanism and treatment.
