We found a unique anatomical variant of the distal ulnar nerve, a neural loop encompassing the flexor carpi ulnaris during Guyon’s canal exploration. Compression by the flexor carpi ulnaris during active wrist movement was suspected as the cause of ulnar neuropathy. The symptom was relieved after neurolysis and release of surrounding tissue. With regard to the ulnar side wrist pain, which is suspicious for ulnar compression syndrome at the wrist level, the surgeon should always suspect anomalous nerve branch as source of compressive neuropathic pain.
