Specialty. Hand surgery, orthopedics. Gamekeeper's thumb (also known as skier's thumb or UCL tear) is a type of injury to the ulnar collateral ligament (UCL) of the thumb. The UCL may be merely stretched, or it may be torn from its insertion site into the proximal phalanx of the thumb. [1] This condition is commonly observed among gamekeepers ...
Bennett's fracture. The Bennett fracture is an oblique intraarticular metacarpal fracture dislocation, caused by an axial force directed against the partially flexed metacarpal. This type of compression along the metacarpal bone is often sustained when a person punches a hard object, such as the skull or tibia of an opponent, or a wall.
A repetitive strain injury (RSI) is an injury to part of the musculoskeletal or nervous system caused by repetitive use, vibrations, compression or long periods in a fixed position. [1] Other common names include repetitive stress injury, repetitive stress disorders, cumulative trauma disorders (CTDs), and overuse syndrome.
In the United Kingdom, a gamekeeper (often abbreviated to keeper) is a person who manages an area of countryside (e.g., areas of woodland, moorland, waterway or farmland) to make sure that there is enough game for hunting, or fish for fishing, and acts as guide to those pursuing them.

A spica splint is a type of orthopedic splint used to immobilize the thumb and/or wrist while allowing the other digits freedom to move. It is used to provide support for thumb injuries (ligament instability, sprain or muscle strain), gamekeeper's thumb, osteoarthritis, de Quervain's syndrome or fractures of the scaphoid, lunate, or first metacarpal.

The tendon is finally inserted on the base of the distal phalanx of the thumb. [ 1 ] 6.7 to 9.7 centimetres (2.6 to 3.8 in) in length, the tendon passes through a long and superficial synovial sheath which, passing obliquely from the radial border of the forearm into the thumb, extends from the proximal border of the extensor retinaculum to the ...
The muscles of the thumb are nine skeletal muscles located in the hand and forearm. The muscles allow for flexion , extension , adduction , abduction and opposition of the thumb . The muscles acting on the thumb can be divided into two groups: The extrinsic hand muscles, with their muscle bellies located in the forearm, and the intrinsic hand ...
The EPB inserts into the base of the first phalanx of the thumb [2] to extend and abduct the thumb at the carpometacarpal and MCP joints. [5] The EPL inserts on the base of the distal phalanx of the thumb. It uses the dorsal tubercle on the radius as fulcrum [2] to help the EPB with its action as well as extending the distal phalanx of the ...
