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 ...
Boxer's fracture of the 5th metacarpal head from punching a wall: Specialty: Emergency medicine, orthopedics: Symptoms: Pain, depressed knuckle [2] Causes: Hitting an object with a closed fist [3] Diagnostic method: Based on symptoms and confirmed by X-rays [3] Treatment: Buddy taping and a tensor bandage, reduction and splinting [4] [3] Medication
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.
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]
Colles himself described it as a fracture that “takes place at about an inch and a half (38mm) above the carpal extremity of the radius” and “the carpus and the base of metacarpus appears to be thrown backward”. [11] The fracture is sometimes referred to as a "dinner fork" or "bayonet" deformity due to the shape of the resultant forearm.

Pipkin: posterior dislocation of hip with avulsion fracture of fragment of femoral head by the ligamentum teres: impact to the knee with the hip flexed (dashboard injury)
Dislocations are commonly caused by sudden trauma to the joint like during a car accident or fall. A joint dislocation can damage the surrounding ligaments, tendons, muscles, and nerves. [2] Dislocations can occur in any major joint (shoulder, knees, hips) or minor joint (toes, fingers). The most common joint dislocation is a shoulder ...
These joints are of the condyloid kind, formed by the reception of the rounded heads of the metacarpal bones into shallow cavities on the proximal ends of the proximal phalanges. [1] Being condyloid, they allow the movements of flexion , extension , abduction , adduction and circumduction (see anatomical terms of motion ) at the joint.
