Description
The metacarpophalangeal joints are formed by the articulations between the heads of the five metacarpal bones with the proximal phalanges. They are condyloid synovial joints which allow movements such as flexion-extension and adduction-abduction (and some rotation during movements such as pinching and grasping). Each metacarpophalangeal joint has a palmar, deep transverse, collateral, and accessory collateral ligaments which help stabilize the joint.
