Avulsion of the Lesser Trochanter Following a Shot Put Sport Session

Abstract

Avulsion of the lesser trochanter is an uncommon injury. In children and adolescents it usually occursas a sports injury via traumatic avulsion of the psoas major tendon. In adults, isolated fractures of thelesser trochanter are most commonly pathological due to metastatic tumor invasion of the proximalfemur. This case report documents how a 14-year-old boy, who presented with an avulsion of thelesser trochanter of the proximal femur following a seemingly atraumatic shot put session at a trackand field event, was diagnosed and successfully treated with a conservative approach.
