The metacarpophalangeal joint consists of an articulation between two bones of the hand: 1. Metacarpal head– large articulating surface, convex shape. 2. Base of proximal phalanx– smaller articulating surface, concave shape. Both the metacarpal and phalangeal articular surfaces are lined by hyaline cartilage.
Each metacarpophalangeal joint is covered by a loose fibrousjoint capsule that attaches close to the margins of the articulating surfaces. The joint capsule is thicker on the medial and lateral aspects – where it is reinforced by collateral ligaments.
The metacarpophalangeal joint capsule is reinforced by several ligamentsand adjacent musculoskeletal structures. The medial and lateral aspects of the joint capsule are reinforced by proper and accessory collateral metacarpophalangeal ligaments. The anterior aspect of the joint capsule is reinforced by the palmar ligament, a dense fibrocartilaginou...
Learn about the metacarpophalangeal joint, a condyloid synovial joint that connects each digit to the palm. Find out its articulating surfaces, ligaments, movements, blood supply and innervation. See how it is affected by injuries such as skier's thumb.
Metacarpophalangeal joint. The palmar aspect of the hand showing the epiphyses of the hand exploded. MCP joints in red. 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 ...

MCP joint arthritis is a condition where the metacarpophalangeal joint (knuckle) of the hand is affected by inflammation and loss of cartilage. It can cause pain, loss of motion and swelling in the fingers. It can be treated with medication, injections, heat, ice, splints, supports, hand therapy and surgery. Learn more about the diagnosis and options from The Hand Society.
Aug 14, 2023 · The metacarpophalangeal (MCP) joints are diarthrodial joints where the large convex heads of the distal aspect of the metacarpals articulate with the concave-shaped proximal aspect of each phalange. The articulating surface of each metacarpal head and proximal phalange is composed of hyaline cartilage. There are five separate MCP joints in each hand and these joints serve as transitions ...

Metacarpophalangeal (MCP) Joint arthritis typically presents with pain, swelling, and limited motion. Inflammatory etiology is much more common than osteoarthritis. Diagnosis is made with a combination of physical exam and radiographs which may demonstrate ulnar deviation of the digits with possible volar subluxation of the proximal phalanx on ...
Oct 24, 2023 · The metacarpophalangeal (MCP) joint, also known as “the knuckle,” is formed by the metacarpal head and proximal phalanx articulation (see Image. Metacarpophalangeal Articulation). This multiaxial joint allows flexion, extension, abduction and adduction. The MCP joint also dynamically coordinates with the interphalangeal (IP) joint to perform thumb opposition and composite finger flexion ...
