2024年10月2日 · 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.

2023年10月30日 · 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.

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] .

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.

2025年2月13日 · 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 …

2024年12月1日 · This review provides a detailed analysis of the anatomy, mechanisms, and management of ligamentous and capsular injuries in metacarpophalangeal joints (MCPJs). The MCPJ is a condyloid joint with unique anatomical features, including a sagittal cam effect that enhances stability in flexion.

2023年4月15日 · 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. Both the metacarpal and phalangeal articular surfaces are lined by hyaline cartilage. Joint Capsule

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.

2010年8月31日 · 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.

Traditionally MCPJ replacements have been of silicone construction inserted into patients with rheumatoid disease. However osteoarthritis (OA) either primary or secondary to trauma does occur. In these patients it has been shown that a more stable MCPJ replacement such as the Ascension Pyrocarbon type is more suited.
