Ischial avulsion injury

Tear of the
hamstrings muscles at the ischial tuberosity seen on MRI (coronal STIR). The arrowheads indicate the tuber and the retracted tendon stump. Significant bleeding around and into the muscles.

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 .
