Pulling your leg: Hip avulsion injury is no joke

In the first of a two-part series, Andrew Hamilton looks at common hip avulsion injuries in athletes, the relationship between injury mechanism and location, and guidelines for avulsion injury diagnosis. An avulsion injury occurs when large or chronic forces transmitted through muscles, tendons, and connective tissue pull a fragment of bone away at the site of its insertion. The local anatomy and skeletal maturity contribute to the propensity to suffer from avulsion injuries. Younger athletes are at much higher risk of avulsion from muscles that insert
