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 stress fracture is a fatigue-induced bone fracture caused by repeated stress over time. Instead of resulting from a single severe impact, stress fractures are the result of accumulated injury from repeated submaximal loading, such as running or jumping. Because of this mechanism, stress fractures are common overuse injuries in athletes. [1]
A scaphoid fracture is a break of the scaphoid bone in the wrist. [1] Symptoms generally includes pain at the base of the thumb which is worse with use of the hand. [2] The anatomic snuffbox is generally tender and swelling may occur. [2] Complications may include nonunion of the fracture, avascular necrosis of the proximal part of the bone ...
The hamate is found within the distal row of carpal bones, and abuts the metacarpals of the little finger and ring finger. [4]: 708–709 Adjacent to the hamate on the ulnar side, and slightly above it, is the pisiform bone. Adjacent on the radial side is the capitate, and proximal is the lunate bone. [4]: 708–709
An ankle fracture is a break of one or more of the bones that make up the ankle joint. [1] Symptoms may include pain, swelling, bruising , and an inability to walk on the injured leg. [ 1 ] Complications may include an associated high ankle sprain , compartment syndrome , stiffness, malunion , and post-traumatic arthritis .
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 ...
intra-articular fracture of base of Thumb metacarpal: axial load along metacarpal in a partially flexed thumb: Bennett's fracture at Whonamedit? Bosworth fracture: David M. Bosworth: fracture of distal fibula with posterior dislocation of the proximal fibula behind the tibia: severe external rotation of the foot "Bosworth fracture dislocation ...
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]
