title: Lateral femoral cutaneous nerve transposition: Renaissance of an old concept in the light of new anatomy.
abstract: Meralgia paresthetica causes pain in the anterolateral thigh. Most surgical procedures involve nerve transection or decompression. We conducted a cadaveric study to determine the feasibility of lateral femoral cutaneous nerve (LFCN) transposition. In three cadavers, the LFCN was exposed in the thigh and retroperitoneum. The two layers of the LFCN canal superficial and deep to the nerve were opened. The nerve was then mobilized medially away from the ASIS, by cutting the septum medial to sartorius. It was possible to mobilize the nerve for 2 cm medial to the ASIS. The nerve acquired a much straighter course with less tension. A new technique of LFCN transposition is presented here as an anatomical feasibility study. The surgical technique is based on the new understanding of the LFCN canal. Clin.
