Metacarpophalangeal (MCP) Joint arthritis typically presents with pain, swelling, and limited motion. Inflammatory etiology is much more common than osteoarthritis. in patients with osteoarthritis, a tendon-splitting approach can be used.

Sep 8, 2024 · A metacarpophalangeal dislocation, or MCP dislocation, is a dislocation of the metacarpophalangeal joint, usually dorsal, caused by a fall and hyperextension of the MCP joint. Treatment is closed reduction unless soft tissue interposition blocks reduction, in which case open reduction is needed.

MCP joint arthritis is most common in the thumb and index fingers due to the stress of pinching. The different joints of the hand are shown in Figure 1. Arthritis means joint inflammation and is a word that is often used to describe pain or a problem at a joint. Arthritis occurs when there is a loss of cartilage.

The metacarpophalangeal joints (MCP) are situated between the metacarpal bones and the proximal phalanges of the fingers. [1] . 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. [1] .

Oct 30, 2023 · The metacarpophalangeal joints (MCP) are a collection of condyloid joints that connect the metacarpus, or palm of the hand, to the fingers. There are five separate metacarpophalangeal joints that connect each metacarpal bone to the corresponding proximal phalanx of each finger.

Feb 13, 2025 · The metacarpophalangeal (MCP) joints are the knuckle joints where the metacarpal bones of the hand meet the proximal phalanges of the fingers. These synovial joints allow flexion, extension, abduction, adduction, and …

Apr 15, 2023 · The metacarpophalangeal joint consists of an articulation between two bones of the hand: Metacarpal head – large articulating surface, convex shape. Base of proximal phalanx – smaller articulating surface, concave shape.

The metacarpophalangeal joint, often shortened to MCP joint, is a joint that connects the metacarpal bones of the hand to the proximal phalanges (the bones in the fingers closest to the hand). There are five MCP joints in each hand, one for each finger.

Each MCP joint of the fingers is formed through the articulation of a relatively large, convex meta-carpal head, with a smaller con-cave base of a corresponding proximal phalanx (Figure 1A). The prominent structure of these joints is evident by observing the dorsal side of the hand while closing and opening a fist.

Aug 31, 2010 · Arthritis of the metacarpophalangeal (MCP) joint can result in considerable pain, disability, and disfigurement of the hand. 1 In the index through small fingers, rheumatoid and inflammatory arthritides are the most common etiologies of joint destruction and cartilage loss.
