Diagnosis: Hamstring Tendon Avulsion

Hamstring strains and tears are common sports-related injuries, occurring due to excessive stretch or sudden load.

Strains can occur in the central muscle belly or at the myotendinous junction, while avulsion of the tendon can occur at its origin at the ischial tuberosity.

Unlike muscle strains, hamstring tendon avulsions are usually treated operatively.

Imaging, usually MRI, can help identify site of hamstring injury.

Ultrasound is less sensitive than MRI for detection of low-grade muscle strains but can identify tendon tears and avulsions.
