Compression neuropathy of the palmar cutaneous branch of the median nerve by the antebrachial fascia.
An isolated compression neuropathy of the palmar cutaneous branch of the median nerve is described in a woman who presented with a small tender mass over the anterior aspect of her distal forearm and complete numbness over the thenar eminence. Surgical exploration revealed thickening of the palmar cutaneous nerve as it passed upwards through the antebrachial fascia on the ulnar aspect of the flexor carpi radialis tendon. Neurolysis of two separate fascicles of the palmar cutaneous branch of the median nerve and excision of a window of antebrachial fascia resulted in complete return of sensation over the thenar eminence.
