Isolated Avulsion of the Distal Head of the Adductor Magnus: A Case Report - Abstract
In the present case, we describe the first reported instance of a non-contact distal adductor Magnus avulsion injury in a collegiate Division I football player. Upon presentation, a 22-year-old male was found to have acute posterolateral corner injury with partial-thickness tears of the fibular collateral ligament (FCL), biceps femoris tendon (BFT), and popliteus tendon (PT). Appropriate management was completed. Two months later, despite no contact or a specific injury after participating in gameplay, the presentation worsened to an acute full-thickness tear of the ischiocondylar (hamstring) portion of the adductor magnus tendon distally from its insertion at the adductor tubercle on the medial condyle of the femur, with surrounding hemorrhage. In this article, we discuss the potential mechanism of injury, provide imaging findings, and discuss management practices regarding avulsion injuries. Further, we emphasize the importance of treatment and full recovery for athletes prior to return to avoid reinjury or placing themselves at greater risk. To the authors’ knowledge, the pathology described in this study has not been reported previously
