The metacarpal bone of the index finger has two centres of ossification: a primary centre in the shaft and a secondary centre in the head. This contrasts to the first metacarpal bone where the secondary centre is found in the base. The ossification process begins in the shaft during prenatal life, and in the head between 11th and 22nd months. [4]
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]
Boxer's fracture; Other names: Metacarpal neck fracture of the little finger, scrapper's fracture, [1] bar room fracture, street fighter's fracture [1] 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 ...
A collateral ligament flanks each MCP joint - one on either side. Each attaches proximally at the head of the metacarpal bone, and distally at the base of the phalynx. Each extends obliquely in a palmar direction from its proximal attachment to its distal attachment. [2]
During osteotomy, the metacarpal is cut and a wedge shape bone fragment is removed to move the bone away from the hand. [35] Postoperative, the thumb of the patient is immobilized using a thumb-cast. Possible complications are non-union of the bone, persistent pain related to unrecognized CMC or pantrapezial disease and radial sensory nerve injury.
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 ...
These bands help stabilise the volar plates over the metacarpal heads. [ 2 ] In contrast to the volar plates of the MCP joints of the fingers, the volar plate of the thumb MCP joint is a thick structure firmly attached to the base of the proximal phalanx.
Rolando fracture – a comminuted intra-articular fracture through the base of the first metacarpal bone; Bennett's fracture – a fracture of the base of the first metacarpal bone which extends into the carpometacarpal (CMC) joint [15] Boxer's fracture – a fracture at the neck of a metacarpal; Broken finger – a fracture of the carpal ...
