Avulsion fracture of the lesser trochanter apophysis

Abstract

Avulsion injuries of the apophysis in adolescents are found most commonly in the pelvis and proximal femur. Among them avulsion fracture of the lesser trochanter apophysis is relatively an uncommon injury. We report a 15 year old patient with an avulsion fracture of the lesser trochanter apophysis on left side who sustained it with a forceful extension of the left hip. Conservative management has been the most popular treatment modality, and we decided to proceed with non-surgical management of the injury since the displacement was not significant. Surgical fixation is indicted when there is a significant displacement or if the patient has higher functional demands.
