Purpose

Rectus femoris avulsion (RFA) injuries in paediatric patients are currently managed conservatively. However, the proximal attachment of the rectus femoris muscle lies in a critical zone in the hip joint with attachments to the anterior hip capsule and anterior inferior iliac spine. Violent avulsions therefore could cause damage to the adjacent acetabular labrum and articular cartilage initiating a process leading to early degenerative changes in the hip. To date, the association between rectus avulsions and labral tears has not been studied.

Method

The complete medical records of patients who were presented to McMaster University Medical Center with rectus femoris avulsions between 1983 and 2008 who were between the ages of 2 and 18 were identified. Patients were included if they had documented plain radiographs and magnetic resonance arthrography images of their hip. MRIs were reviewed by an independent musculoskeletal radiologist blinded from the history of the patients.
