These bands help stabilise the volar plates over the metacarpal heads. [2] In contrast to the volar plates of the MCP joints of the fingers, the volar plate of the thumb MCP joint is a thick structure firmly attached to the base of the proximal phalanx. It forms the bottom of a two-sided box, the sides of which are made up of the collateral ...
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 ...
The palmar plate is supported by a ligament on either side of the joint called the collateral ligaments, which prevent deviation of the joint from side to side. The ligaments can partially or fully tear and can avulse with a small fracture fragment when the finger is forced backwards into hyperextension.
The palmar carpometacarpal ligaments (or volar) are a series of bands on the palmar surface of the carpometacarpal joints that connect the carpal bones to the second through fifth metacarpal bones. The second metacarpal is connected to the trapezium. The third metacarpal is connected to the trapezium, to the capitate, and to the hamate. The ...

Specialty: Orthopedics, emergency medicine: Symptoms: Pain, bruising, and swelling of the wrist [1] Usual onset: Sudden [1] Types: Colles' fracture, Smith's fracture, Barton's fracture, Hutchinson fracture [2] Causes ...
The neck of a metacarpal is a common location for a boxer's fracture, but all parts of the metacarpal bone (including head, body and base) are susceptible to fracture. During their lifetime, 2.5% of individuals will experience at least one metacarpal fracture. Bennett's fracture (base of the thumb) is the most common. [4]

Fracture with a dorsal tilt. Dorsal is left, and volar is right in the image. There are a number of ways to classify distal radius fractures.Classifications systems are devised to describe patterns of injury which will behave in predictable ways, to distinguish between conditions which have different outcomes or which need different treatments.
