metakarpálisphalangealis

Metakarpophalangeal is a medical term referring to the joints located in the hand. Specifically, these are the articulations between the metacarpal bones of the palm and the proximal phalanges, which are the first bones of the fingers. These joints are commonly known as the knuckles. They are classified as condyloid joints, allowing for a wide range of motion. The movements facilitated by the metacarpophalangeal joints include flexion, extension, abduction, and adduction. This allows for the grasping and fine manipulation of objects. The palmar and collateral ligaments provide stability to these joints. Inflammation or injury to the metacarpophalangeal joints can lead to pain, stiffness, and reduced hand function. Conditions such as rheumatoid arthritis commonly affect these joints.
