The recurrent motor nerve, a possible cause of denervation following hamstring injury and repair: acadaveric case

ABSTRACT

Severe hamstring injuries warranting surgical repair are rare and mainly affect athletes, young and middle-aged people. A minority of these patients report postoperative complications of denervation. Symptoms of denervation range from muscle weakness to sciatic nerve palsy. Recent anatomical observations suggest that a recurrent motor nerve, which inserts into the proximal ham-strings, may be responsible for this denervation. The recurrent motor nerve was identified through cadaveric dissection and the site of nerve penetration into the muscle, measured 1.5 cm from the ischial tuberosity. This distance is significantly shorter than previous studies report. Awareness of this nerve branch is an important consideration in hamstring injury and repair. Due to its course, the recurrent motor nerve’s name is also a source of discussion:
