Median nerve compression by a radially inserted palmaris longus tendon after release of the antebrachial fascia: A complication of carpal tunnel release

We describe a case that had recurrent median nerve compression after releas e of the antebrachial fascia in carpal tunnel release. The nerve was compre ssed by a palmaris longus tendon that was inserted radially into the thenar fascia. After decompression (detachment of the tendon) the patient had sym ptom relief. Release of the antebrachial fascia in the presence of this ten don variant carries a risk of median nerve compression by the tendon. (J Ha nd Surg 2000;25A:955-958.
