Resection of the Proximal Tendinous Portion in Avulsion of the Semimembranosus Tendon from the Ischial Tuberosity in an Adult: A Case Report / 대한정형외과학회잡지

ABSTRACT

Hamstrings are composed of the semimembranosus and semitendinosus and biceps femoris muscles and act as extensors of the thigh and flexors of the leg. Avulsion of the hamstring from the ischial tuberosity has a high rate of incidence among adolescents and young adults, and most often results from exercises that require sudden acceleration and deceleration, such as running, soccer, hurdling and basketball. This injury, caused by forcible flexion of the hip with the knee extended, is commonly called "hurdlers' injury". There have been several reports describing treatment of hamstring proximal tendon avulsion injury by open reduction and internal fixation. We describe a case of semimembranosus tendon avulsion from the ischial tuberosity in the adult that was satisfactorily treated by resection of the proximal portion of the tendon.
