[The modified Lamberty and Cormack's flap for neuropathies of the ulnar nerve at the elbow].

Surgical treatment of ulnar nerve syndrome at the elbow gives good results in the majority of cases but there are sometimes incomplete results or recurrences that can lead to iterative procedures. This iterative surgery is responsible for painful neurological sequelae often resistant to pharmacological treatments. In these selected resistant cases, we made the choice of a surgical treatment associating a neurolysis of the ulnar nerve and wrapping with a vascularized flap modified from Lamberty and Cormack. This retrospective study focused on six cases with an average follow-up of 30 months. The results showed an improvement in all patients, especially for the two criteria which best reflect the neuropathic pain: DN4 questionnaire and the visual analog scale of pain. Even if it is a short study, it commits us to continue to apply the principle of covering ulnar neuropathy at the elbow by a vascularized flap.
