AIM: Femoral nerve palsy after total hip arthroplasty can result from several causes. Delayed neuropathies of the femoral nerve because of excessive granuloma in loosened implants are a rare condition. CASE REPORT: We report the case of delayed neuropathy of the femoral nerve after cementless total hip arthroplasty because of aseptic loosening of the cup. Electrophysiologic evaluation revealed a severe lesion of the femoral nerve with sensomotoric deficits. An abdominopelvic computed tomography (CT) scan revealed an excessive granuloma with a large intrapelvic portion. After revision of the loosened acetabular component and the femoral nerve and removal of the granuloma the neurologic symptoms improved. CONCLUSION: Regular (1-2 years) clinical and radiological follow-ups are requested after total hip arthroplasty to prevent excessive loosening of implants, excessive granuloma and severe sequelae like nerve damage.
