Abstract
Posttraumatic proximal hamstring avulsion: case report and literature overview
In sports medicine, hamstring tears and elongations are common, well-known injuries. They happen suddenly while sprinting. A less known injury is the proximal hamstring avulsion from the ischial tuberosity, which can be complete (all tendons) or partial.
This article reports the case of a 40-year-old triathlete who suffered a complete proximal hamstring avulsion while falling from a mountain bike. She presented with posterior thigh pain and was limping. The physical examination revealed a palpable gap distal to the ischial tuberosity and a decreased strength in knee flexion and hip extension. An ultrasound and MRI were used to confirm the diagnosis and to assess the extent of the tendon retraction.
The injury mechanism, clinical picture, treatment options and rehabilitation are described. A surgical treatment was chosen for this patient because of her age and the level of physical activity. One year post surgery, the patient was running and cycling at a low intensity. Thirty months after surgery, cycling at a high intensity was painless, but sprinting and sitting on a hard chair were still painful. Isokinetic strength testing showed no difference in knee flexion strength between both legs.
