A boxer's fracture is the break of the fifth metacarpal bone of the hand near the knuckle. [4] Occasionally, it is used to refer to fractures of the fourth metacarpal as well. [1] Symptoms include pain and a depressed knuckle. [2] Classically, it occurs after a person hits an object with a closed fist. [3]
A fracture of the fourth and/or fifth metacarpal bones transverse neck secondary due to axial loading is known as a boxer's fracture. [1] [[[Boxer%27s_fracture#{{{section}}}| contradictory]]] The fifth metacarpal bone is the most common bone to be injured when throwing a punch.

The movements permitted in the second through fifth carpometacarpal joints most readily observable in the (distal) heads of the metacarpal bones. The range of motions in these joints decrease from the fifth to the second CMCs. [8] The second to fifth joints are synovial condyloid joints with a nominal degree of freedom (flexion/extension). The ...
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 ...
The index metacarpal is the most firmly fixed, while the thumb metacarpal articulates with the trapezium and acts independently from the others. The middle metacarpals are tightly united to the carpus by intrinsic interlocking bone elements at their bases. The ring metacarpal is somewhat more mobile while the fifth metacarpal is semi ...
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 ...
