Proximal sciatic neuropathy secondary to hamstring tendon avulsion.

We herein present the exceptional case of a patient, who injured a sciatic nerve due to avulsion of proximal hamstring tendon in a motorcycle accident. The 63-year-old man was diagnosed firstly with an incomplete fracture of distal femur. A foot drop on the right side was observed when the full-length cast was removed two months later. The patient was referred to the neurology clinic and was diagnosed with a sciatic nerve lesion at the proximal level of the biceps femoris. Magnetic resonance imaging of the thigh showed a proximal avulsion of hamstring muscles tendon. The patient did not improve by short-term physiotherapy and neurosurgical intervention. Sciatic nerve injury can be a result of proximal hamstring avulsion in events such as motorcycle accidents even in the absence of complete or major femur fracture.
