title: Unusual Communications between the Cutaneous Branches of Ulnar Nerve in the Palm.
abstract: Variations of dorsal and volar digital cutaneous branches of ulnar nerve are of tremendous clinical importance for successful regional nerve blocks, skin flaps, carpal tunnel release and placement of electrodes for electrophysiological studies. With the aforementioned clinical implications it is worth to report the variations of cutaneous branches of ulnar nerve. In the current case, we have encountered a rare variation (Kaplan`s anastomosis) of ulnar nerve, in the right upper limb. We have noticed that the dorsal cutaneous branch of ulnar nerve divided into three branches, the lateral two branches supplied the skin of the medial one and half fingers of the dorsum of hand. The medial branch established communications with the superficial branches of ulnar nerve and distributed to the skin of the one and half fingers of the volar aspect of hand. The possible outcome of this communications is discussed. Course and distribution of ulnar nerve on the contralateral side was found to be normal.
