Bilateral palmaris profundus in association with bifid median nerve as a cause of failed carpal tunnel release.
This is a case in which an anomalous tendon of the palmaris profundus was found running on the anterior surface of the median nerve, dividing the nerve into 2 branches at the wrist bilaterally. Excision of the tendon at the time of re-exploration of the carpal tunnel resulted in complete relief of carpal tunnel symptoms.
