A broken finger or finger fracture is a common type of bone fracture, affecting a finger. [1] Symptoms may include pain, swelling, tenderness, bruising, deformity and reduced ability to move the finger. [2] Although most finger fractures are easy to treat, failing to deal with a fracture appropriately may result in long-term pain and disability.
Human vestigiality. The muscles connected to the ears of a human do not develop enough to have the same mobility allowed to monkeys. Arrows show the vestigial structure called Darwin's tubercle. In the context of human evolution, vestigiality involves those traits occurring in humans that have lost all or most of their original function through ...
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 tooth that has experienced trauma may become loose due to the periodontal ligament becoming damaged or fracture to the root of the tooth. Splinting ensures that the tooth is held in the correct position within the socket, ensuring that no further trauma occurs to enable healing. [37] A splint can either be flexible or rigid.
Scaphoid fracture. 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]
The hamate bone is the bone most commonly fractured when a golfer hits the ground hard with a golf club on the downswing or a hockey player hits the ice with a slap shot. The fracture is usually a hairline fracture, commonly missed on normal X-rays. Symptoms are pain aggravated by gripping, tenderness over the hamate and symptoms of irritation ...
Vestigiality. In humans, the vermiform appendix is sometimes called a vestigial structure as it has lost much of its ancestral digestive function. Vestigiality is the retention, during the process of evolution, of genetically determined structures or attributes that have lost some or all of the ancestral function in a given species. [1]
Specialty. Hand surgery. The Rolando fracture is a type of broken finger involving the base of the thumb. [1] It is an intra-articular fracture. [2] It was first described in 1910 by Silvio Rolando. [3] It is typically T- or Y-shaped.
