It is connected with the extensor pollicis longus to The abductor pollicis brevis muscle is a thin subcutaneous muscle located laterally in the thenar eminence of the hand, and is one of the intrinsic muscles of the hand. Symptoms result from a narrow first dorsal compartment and associated tendinosis of the enclosed extensor pollicis brevis and/or abductor pollicis longus (APL). Surgical intervention, offered when conservative measures fail to adequately relieve symptoms, requires a detailed understanding of potentially aberrant anatomy in order to avoid persistence or recurrence of symptoms. Gliding resistance of the extensor pollicis brevis and abductor pollicis longus tendons was measured in seven wrist positions: 60 degrees extension, 30 degrees extension, 0 degrees, 30 degrees flexion, 60 degrees flexion in neutral deviation and 30 degrees ulnar deviation, 15 degrees radial deviation in neutral extension/flexion. 2019-07-31 · It travels through the carpal tunnel which is the point connecting the palm and forearm, and goes into the thumb. This muscle is located between the two muscles which facilitate flexion of the thumb, namely the Flexor Pollicis Brevis and the Abductor Pollicis.
