What type of joint is metacarpophalangeal?
The metacarpophalangeal (MCP) joints are diarthrodial joints where the large convex heads of the distal aspect of the metacarpals articulate with the concave-shaped proximal aspect of each phalange. The articulating surface of each metacarpal head and proximal phalange is composed of hyaline cartilage.
What is the function of metacarpophalangeal joint?
These joints are of the condyloid kind, formed by the reception of the rounded heads of the metacarpal bones into shallow cavities on the proximal ends of the proximal phalanges. Being condyloid, they allow the movements of flexion, extension, abduction, adduction and circumduction at the joint.

How is the range of motion of the metacarpal limited?
The movements in this axis are limited by ligamentous structures that surround the joint and antagonistic muscles. The full range of motion in this axis is around 25-30°. This fairly small range of motion belongs mostly to abduction. These movements are limited mainly by the shape and width of the metacarpal head, and by collateral ligaments.
