Joints of the hand, X-ray Interphalangeal ligaments and phalanges. Right hand. Deep dissection. Posterior (dorsal) view. The PIP joint exhibits great lateral stability. Its transverse diameter is greater than its antero-posterior diameter and its thick collateral ligaments are tight in all positions during flexion, contrary to those in the metacarpophalangeal joint.
They limit extension at these joints (together with the palmar ligaments). [1] On each side of the interphalangeal joints of the fingers are diagonally placed fibrous bands. The proximal ends of the bands are near the dorsal phalanges of the hand and the distal ends of the bands are near the palmar margins of the digits. [citation needed]
In the human hand, palmar or volar plates (also referred to as palmar or volar ligaments) [1] are found in the metacarpophalangeal (MCP) and interphalangeal (IP) joints, where they reinforce the joint capsules, enhance joint stability, and limit hyperextension.
Collateral ligaments of interphalangeal joints are associated with the interphalangeal joints of both the hands and feet: Collateral ligament of interphalangeal joints of hand; Collateral ligaments of interphalangeal joints of foot
An open fracture may be another reason. Surgery will put the finger in a neutral position and drill a wire through the distal interphalangeal joint (DIP) to the proximal interphalangeal joint (PIP), forcing immobilization.
The joints in the hand are joints found at the distal end of the upper limb. The joints are: In the wrist there is the radiocarpal joint between the radius and carpus. Between the carpal bones are the intercarpal articulations and the midcarpal joint.
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]
Gamekeeper's thumb and skier's thumb are two similar conditions, both of which involve insufficiency of the ulnar collateral ligament (UCL) of the thumb. The chief difference between these two conditions is that skier's thumb is generally considered to be an acute condition acquired after a fall or similar abduction injury to the metacarpophalangeal (MCP) joint of the thumb, whereas gamekeeper ...
