Functional anatomy of the flexor tendon system of the hand

Abstract

The beautifully coordinated functions of the hand depend on the tendon apparatus acting on the articulated skeletal elements. The flexor muscles are situated on the antero-medial aspect of the forearm, with their tendons crossing the wrist and finger joints in a wonderfully arranged system to provide the infinite movements possible. The anatomical details of the extrinsic and intrinsic flexor apparatus are presented, with their functions described as anticipated by their origins, insertions, and the joints they cross and thus can act upon.
