An accessory abductor pollicis longus (AAPL) tendon is present in more than 80% of people and a separate muscle belly is present in 20% of people. In one study, the accessory tendon was inserted into the trapezium (41%); proximally on the abductor pollicis brevis (22%) and opponens pollicis brevis (5%); had a double insertion on the trapezium and thenar muscles (15%); or the base of the first metacarpal (1%). [7]
A rare case of selective absence of the flexor pollicis brevis and abductor pollicis brevis with an intact functioning opponens pollicis and flexor pollicis longus which has not been previously reported is herewith presented. Congenital absence of the thenar muscles with or without absence of the flexor pollicis longus has been reported previously.

Extensor pollicis longus (EPL) muscle is a muscle of the deep compartment in the posterior compartment of the forearm.It passes through the 3 rd extensor compartment of the wrist, then continues laterally towards the thumb around Lister's tubercle. The tendon of EPL defines the ulnar border of the anatomical snuff box.. It is one of the extrinsic muscles of the hand.

Abductor pollicis longus is a muscle found in the posterior compartment of the forearm. It is one of the five deep extensors in the forearm, along with the supinator, extensor pollicis brevis, extensor pollicis longus and extensor indicis. The main action of extensor pollicis longus is extension of the thumb at the metacarpophalangeal and interphalangeal joints. Extension at the metacarpophalangeal joint occurs in synergy with extensor pollicis brevis muscle. When the thumb reaches the full extension or abduction, extensor pollicis longus can also assist in adduction of the thumb.
