Wrist structures prone to injury are the triangular fibrocartilage complex and the scapholunate ligament. [1] Wrist sprains may occur when a ligament is ruptured or lacerated in severe trauma, stretched or twisted. [1] Commonly, wrist pain is caused by sudden load-bearing or twisting effects, such as falling from a height with an outstretched ...
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 ...
Fracture of the tuft of the finger. Finger injuries are usually diagnosed with x-ray and can get to be considerably painful. The majority of finger injuries can be dealt with conservative care and splints. However, if the bone presents an abnormal angularity or if it is displaced, one may need surgery and pins to hold the bones in place.
The equivalent injury to a ligament is a sprain. [1] Generally, the muscle or tendon overstretches and partially tears, under more physical stress than it can withstand, often from a sudden increase in duration, intensity, or frequency of an activity. Strains most commonly occur in the foot, leg, or back.
The radial collateral ligament (external lateral ligament, radial carpal collateral ligament) extends from the tip of the styloid process of the radius and attaches to the radial side of the scaphoid (formerly navicular bone of the hand), immediately adjacent to its proximal articular surface and some fibres extend to the lateral side of the trapezium (greater multangular bone).
A distal radius fracture, also known as wrist fracture, is a break of the part of the radius bone which is close to the wrist. [1] Symptoms include pain, bruising, and rapid-onset swelling. [1] The ulna bone may also be broken. [1] In younger people, these fractures typically occur during sports or a motor vehicle collision. [2]
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 ...
Trapeziometacarpal osteoarthritis (TMC OA) is, also known as osteoarthritis at the base of the thumb, thumb carpometacarpal osteoarthritis, basilar (or basal) joint arthritis, or as rhizarthrosis. [ 3 ] [ 1 ] [ 2 ] This joint is formed by the trapezium bone of the wrist and the metacarpal bone of the thumb.
