Ischial avulsion injuries are considered the most severe hamstring injury and often require surgical repair.

Epidemiology

These are rare injuries and are more common in adolescents than in adults .

Pathology

In adolescents, the injury involves avulsion of the apophysis causing a small fragment of bone to detach .

In adults, ischial avulsions are usually tendinous only with no bone involvement. The most common pattern being the conjoint tendon (of semitendinosus and biceps femoris) fully detaching with a partial or full-thickness injury of semimembranosus .
