metakarpofalangeális

Metakarpofalangeális, often abbreviated as MCP, refers to the joints located between the metacarpal bones of the hand and the phalanges, which are the bones of the fingers. Specifically, there are five MCP joints in each hand, corresponding to each finger. The MCP joint of the thumb is formed by the first metacarpal bone and the first phalanx, while the MCP joints of the other four fingers are formed by the second through fifth metacarpal bones and their respective first phalanges. These joints are classified as condyloid joints, allowing for a range of movements including flexion, extension, abduction, adduction, and circumduction. This flexibility is crucial for the intricate manipulation and dexterity required for various hand functions, from grasping objects to fine motor tasks. The MCP joints are supported by strong ligaments, including the collateral ligaments and the volar plate, which help to stabilize the joint and prevent excessive movement. Inflammation or injury to these joints, such as in conditions like rheumatoid arthritis or sprains, can significantly impair hand function and cause pain.
