• Resumen

  • The present case report describes a rare finding of dorsal branch of the ulnar nerve which originated from the junction of upper fourth and lower three fourth of the forearm, passed between the two heads of flexor carpi ulnaris and then descended along the medial border of the extensor surface forearm in the superficial fascia. On the dorsal aspect of the wrist, it divided into two branches, a medial and a lateral branch. The medial branch joins throughout the hypothenar eminence with the deep branch of the ulnar nerve and the lateral branch became cutaneous on the medial half of dorsum of hand and medial two and half digits i.e radial and ulnar side of little and ring finger and the ulnar side of middle finger.
