Entrapment of the palmar cutaneous branch of the median nerve by a normal palmaris longus tendon.
An anomalous course of the palmar cutaneous branch of the median nerve was noted in a patient with symptoms of compression of the median nerve and its palmar cutaneous branch at the wrist level. The palmar cutaneous branch of the nerve pierced the tendon of a normal palmaris longus muscle near its insertion. Decompression of the median nerve and its palmar cutaneous branch was performed, with complete relief of symptoms.
