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 ...
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]

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 plantar plate is firm but flexible fibrocartilage with a composition similar to that found in the menisci of the knee (composed roughly of 75% type-I collagen), and can thus withstand compressive loads and act as a supportive articular surface. Most of its fibers are oriented longitudinally, in the same direction as the plantar fascia, and ...
Healing of the fracture with a non-anatomic deformity (frequently, a volar flexed "humpback") can also lead to post-traumatic arthritis. Non-unions can result in loss of blood supply to the proximal pole, which can result in avascular necrosis of the proximal segment. Scaphoid fractures may be difficult to diagnose via plain x-ray.
An X-ray revealed an undisplaced fracture, New Zealand Cricket announced Saturday. Williamson had returned from seven months out with a knee injury and scored 78 in the eight-wicket win. Tom ...
The ulnar collateral ligament of the thumb runs along the ulnar side of the metacarpo-phalangeal joint of the thumb. The ulnar collateral ligament is an important stabilizer of the thumb. It is on the radial side of the wrist, but on the ulnar side of the thumb.
