The proximal hamstring complex is frequently injured in athletes, traditionally occurring in waterskiing, sprinting and hurdles. However, more recently it is increasingly being reported in a variety of different sports. The hip and knee joint are stabilized by the hamstring muscles due to eccentric contractions, which occur when a muscle contracts whilst passively stretched. This happens to the hamstring muscle during hip flexion and knee extension. Injuries are much more common during eccentric contractions, 12% of hamstring injuries are proximal and of these 9% are complete. The current literature advocates surgical intervention of complete proximal hamstring avulsion injuries with early surgical management associated with better clinical outcomes in terms of pain, function and return to sport. The diagnosis of this type of injury can be challenging due to the complexity of the surrounding anatomy. Injury classifications have been produced in order to understand, diagnose and manage these injuries appropriately. We present a rare variant of a proximal hamstring injury; with plastic deformation of the proximal tendons with the insertions at the ischial tuberosity intact. This type of injury has not previously described or classified in the literature.
