Thumb Joints Diagram In this article, i’ll quickly show you how to identify the joints in your thumb. in this series of articles, i’ll go through some of these terms along with some helpful diagrams and shed some light on the common language of hand and arm surgery. The thumb is located on the radial (lateral) side of the hand, positioned opposite the other four fingers. it extends from the base of the hand, originating at the carpometacarpal (cmc) joint, and ends at the tip of the distal phalanx.

The thumb is the first digit of the hand that functions differently from the other fingers, which has the greatest range of motion and movement allowing for flexion, extension, abduction, adduction, opposition, and retropulsion.

The skeleton of the thumb consists of the first metacarpal bone which articulates proximally with the carpus at the carpometacarpal joint and distally with the proximal phalanx at the metacarpophalangeal joint. this latter bone articulates with the distal phalanx at the interphalangeal joint. The metacarpophalangeal joint of the thumb is different from that of the other fingers. it is a hinge and allows only a flexion movement (80–90°) and in hypermobile individuals some extension. Fig. 9: illustration and mr images (fat suppressed t2 weighted image coronal, axial view) of metacarpophalangeal joint of the thumb. collateral ligaments are painted as yellow on illustration and noted by yellow arrows on mr images. The thumb has its own set: the extensor pollicis longus and brevis straighten the thumb, and the abductor pollicis longus pulls it away from the palm for a wider grip.
