Kim, Hwang, Moon, Kim, Song, and Kang: Treatment of Avulsion Fracture of Proximal Rectus Femoris with Suture Anchor

Abstract

Avulsion injuries of the anterior inferior iliac spine, which is the origin of the rectus femoris muscle, are sometimes reported in children and adolescents, but acute avulsion injuries with complete rupture of the rectus femoris are very rare in adults. We treated a case of avulsion fracture of the anterior inferior iliac spine with suture anchors in an adult and achieved a favorable outcome. Thus, we report the case with a review of literature.
