Two patients are presented suffering from meralgia paresthetica, owing to neurotmesis of the lateral femoral cutaneous nerve following bone-graft harvesting from the iliac crest with a cylindrical osteotome. Despite this donor-site complication, the advantages of a coring technique as compared with traditional bone-graft harvesting techniques are numerous: better cosmetic results, less pain, no need for general anesthesia, shorter hospitalization, and a minimum of donor-site morbidity. Also, this technique has proven itself easy and effective. To minimize donor-site morbidity, some clinical recommendations to avoid neurotmesis are given with regard to the anatomy and anatomic variations of the lateral femoral cutaneous nerve.
