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] .

2023年8月14日 · 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.

2023年10月24日 · The upper limb bud appears around the 4th week of gestation. Around the 6th to 7th week of gestation, the MCP joint forms from a cavity in the mesenchyme between developing bones. The joint capsule and its associated ligaments also arise from the mesenchyme in this area. The sesamoid bones of the 1st MCP joint do not appear until approximately ...

This article discusses the ligamentous structures of the metacarpophalangeal (MP) joints (see the first image below), proximal interphalangeal (PIP) joints, and distal interphalangeal (DIP) joints....

2025年2月24日 · Metacarpophalangeal (MCP) joints are condyloid synovial joints between the metacarpal bones and proximal phalanges of the hands. This article is focused on the metacarpophalangeal joints of the fingers. Each joint occurs between the round head of the metacarpal and the shallow base of the proximal phalanx 1,2.

2019年4月21日 · Effective edema control serves as the chief priority the initial three weeks following surgery to effectively limit pain, allow greater range-of-motion, and limit the formation of scar tissue. Custom-fabricated orthoses, both for immobilization and mobilization purposes, play an integral role in a successful outcome.

2019年1月26日 · Metacarpophalangeal (MCP) arthritis is more frequently associated with rheumatoid arthritis than with osteoarthritis. There are distinct presentations and treatment options for the two different etiologies.

Palmar approach to metacarpophalangeal joint of the finger. 2. Surgical anatomy. The tendons of the flexor digitorum superficialis and profundus are closely applied to the volar plate and volar capsule of the MCP joints. In the thin subcutaneous tissue, identify and protect the collateral neurovascular bundles of the ulnar and median nerves.
