Rupture of the Ischial Origin of the Hamstring Muscles.

Abstract

There are few reports on the rupture of the ischial origin of the hamstring muscles among the rupture of all muscles. We report a case of rupture of the ischial origin of the hamstring muscles. A 48-year-old male complaining chiefly of pain in the posterior part of his right thigh after slipping on rollers while carrying something. He fell with his right knee extended and his right hip flexed in exessive flexion. He felt pain around the posterior part of his right thigh, and could not stand up and walk. We recognized recess at the distal part of the ischial tuberosity and a bulge at the posterior center part of the thigh. MRI (T2_??_) imaging showed a low signal area that was assumed to be the avulsive part. 3 days after injury, we performed surgery with reattachment of the avulsive muscles to the ischium. 9 months after surgery, he returned to his job.
