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 ...
A Jersey finger is a traumatic rupture of the flexor digitorum profundus (FDP) tendon at its point of attachment to the distal phalanx. [4] This injury often occurs in American football when a player grabs another player's jersey with the tips of one or more fingers while that player is pulling or running away. [5]
Open fractures, in which the skin is broken, also increase the risk of infection and complications, especially if the wound is dirty or parts have to be removed. [1] Open fractures are usually operated on. [1] A Busch fracture is a specific type of finger fracture where the base of a distal phalanx is affected. [5]
The Müller AO Classification of fractures is a system for classifying bone fractures initially published in 1987 [1] by the AO Foundation as a method of categorizing injuries according to therognosis of the patient's anatomical and functional outcome. "AO" is an initialism for the German "Arbeitsgemeinschaft für Osteosynthesefragen", the ...
A Salter–Harris fracture is a fracture that involves the epiphyseal plate (growth plate) of a bone, specifically the zone of provisional calcification. [2] It is thus a form of child bone fracture. It is a common injury found in children, occurring in 15% of childhood long bone fractures. [3]
The phalanges of the foot differ from the hand in that they are often shorter and more compressed, especially in the proximal phalanges, those closest to the torso. [3] A phalanx is named according to whether it is proximal, middle, or distal and its associated finger or toe. The proximal phalanges are those that are closest to the hand or foot.
intra articular comminuted fracture of base of first metacarpal: axial load along the metacarpal causing splitting of the proximal articular surface: Rolando's fracture at Wheeless' Textbook of Orthopaedics online Runner's fracture: Running: stress fracture of distal fibula 3–8 cm above the lateral malleolus: repeated axial stress on fibula
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. It can also occur as a ...
