Abstract OBJECTIVE Obturator neuralgia consists of pain radiating from the obturator nerve territory to the inner thigh. METHODS We report a case of idiopathic obturator neuralgia resulting from compression of the obturator nerve in the obturator canal, causing a case of nerve entrapment syndrome. The pain was characterized by its localization in the inguinal region and anterointernal side of the thigh, going down to the internal side of the knee. It was worse when standing or in a monopodal stance. Walking caused pain and a limp. RESULTS The diagnosis was confirmed by an analgesic block. The analgesic was infiltrated using a posterior approach and computer-assisted tomography, allowing the quality and specificity of the infiltration to be judged. CONCLUSION We describe, for the first time, a treatment of obturator neuralgia by a minimally invasive laparoscopic approach. This involved an obturator nerve neurolysis and section of the internal obturator muscle and the obturator membrane.

Obturator Neuralgia

Introduction. Idiopathic obturator neuralgia is a rare chronic pain condition. It consists of pain radiating from the obturator nerve territory to the inner thigh. However, the symptomatic obturator neuralgia is commonly caused by the obturator canal bowel hernia that causes painful compressive neuropathy in more than 85% of the cases. Case report. A 61-year-old female who underwent right femoral amputation due to the occlusion of the aortofemoral vascular graft, complained of the pain characterized by its localization in the inguinal region and anterointernal side of the right inner thigh. Computer tomography and MRI findings excluded obturator canal herniation or lumbar plexopathy. A diagnosis of the obturator neuralgia was confirmed by an analgesic block of the obturator nerve. Thereafter, the neurolitic blockade of the right obturator nerve was done. The complete pain relief was achieved. Pain relief was complete in three-month follow-up period. Conclusion. Neurolitic blockade is an efficacious method in treating chronic pain caused by the idiopathic obturator neuralgia.
