Deformity Ulna drift & volar dislocation Causes of MCPJ Deformity Ulna Drift / Ulna Dislocation 1. Physiological - gravity - lateral pinch pressure - power grip 2. Anatomic - shape of MC heads - collateral ligament length & orientation - intrinsics to LF asymmetric (hypothenars strong) 3. Pathological - joint / capsule instability due to bony erosions - collateral ligament stretching due to ...

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.

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] .

Although several types of instability exist, this paper focuses on palmar subluxation and an associated ulnar drift of the MCP joints—a common pair of impairments typical in rheumatoid arthritis (RA). Treatment typically includes improving alignment and function.

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 …

2023年10月30日 · Overview of the bones of the hand and wrist. 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.

MCP joint arthritis may cause pain, loss of motion, and swelling. These changes often come on gradually and may not be noticed right away. These symptoms may feel worse when gripping or grasping, such as when turning a key or opening a jar. Patients with arthritis sometimes have weak hands and may tend to drop objects due to sudden pains.

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 · In this article, we shall look at the anatomy of the metacarpophalangeal joint – its articulating surfaces, ligaments and clinical correlations. The articulating surfaces of the metacarpophalangeal joints of the hand. Explore, cut, dissect, annotate and manipulate our 3D models to visualise anatomy in a dynamic, interactive way.

Arthritis of the metacarpophalangeal joint can result in considerable disability and pain. Inflammatory, posttraumatic, crystalline, and osteoarthritis are common etiologies of joint disease.
