Proximal hamstring avulsions (PHA) are rare lesions that can cause permanent functional alterations and a very high risk of re-tear (12% to 31%) [1]. They are present in 9 - 12% of all lesions in this muscle group [2] and most often occur in athletes who require rapid acceleration (running, hurdling) or “ballistic" movements (skiing, skating, weight lifting) [3,4].

Proximal hamstrings comprise 3 tendons: the semitendinosus, the long head of the biceps femori and the semimembranosus (the latter 2, merged at their origin by the conjoined tendon). The mechanism of injury corresponds to eccentric contraction of the PH when trying to resist a fall, with the hip in flexion and the knee in extension. Acute pain is usually reported in the posterior thigh, sometimes accompanied by an audible pop and in some occasions with numbness and tingling in the sciatic nerve distribution [5].
