The isolated lesser trochanter fracture is a quite unusual affection typical of child and young teenager. It is usually caused by strong traction by ileo-psoas muscle, tipical of sprinters and soccer players. This article reports the case of a 14-year-old boy with an isolated avulsion of the lesser trochanter due to a rush during a soccer match. After a conservative treatment a magnetic resonance imaging (MRI) was performed at 30 days after the trauma. The exam demonstrated the formation of fibrous tissue between the fracture surfaces. At 24 months the patient could walk and run and he has not developed any late complications. The isolated lesser trochanter fracture in the young teenager can be treated conservatively even when there is a remarkable bony displacement. In the presented case the MRI demonstrates that the good functional outcome is not due to fracture healing, but to the formation of fibrous tissue that allows the functionality of the ileo-psoas muscle.
