Introduction: The ulnar nerve is one of the two terminal branches of the medial cord. It passes down the medial aspect of the arm and runs posterior to medial epicondyle to enter the forearm without branching. Previously, ulnar nerve variations have been consistently located in origin or course of the distal branches. Case Report: In this present case, an unreported rare bifurcation of ulnar nerve was seen in the left lower arm of a 65 year male cadaver with the resulting posteromedial and anterolateral branches arising above the medial epicondyle in.Its phylogeny and implications are discussed in detail. Conclusion: A lack of awareness of variations might complicate surgical repair and may cause ineffective nerve blockade.
