Abstract

Abductor pollicis longus is a muscle of deep group of extensor compartment of the forearm. It is an abductor of the thumb. The aim of the study is to observe the variations in the number of tendons and the point of distal attachment of this muscle tendon. This study included 32 upper limbs of cadavers, both male and female which were dissected in the Department of Anatomy, Kasturba Medical College, Manipal. A significant variations were observed in the abductor pollicis longus. Majority of muscle having more than one tendon. Tendons vary from 1–4. Their point of insertion also varies. Some are inserted to 1st metacarpal, some to trapezium and some are to the both. Also found one which is attached to base of proximal phalynx of the thumb. This muscle helps in movement and stabilization of thumb. Accessory tendons have been found to be a feasible option for tendon transplants in reconstructive surgeries of the hand. Injuries in one tendon can be compensated by the remaining tendons. Thus, awareness in the variations of this muscle is important for surgeons.
