In the hand form and function of the bones are so closely related to each other, like in no other place in the body (Kamath et al., 2011).
The metacarpal bones articulate with the wrist bones and with the fingers (Freivalds, 2011).
Fractures of the metacarpals usually occur from high impact injuries, like a punch (Fernandez-de-las-Penas, Cleland and Dommerholt, 2016).
Hand fractures can be complicated by deformity from no treatment; stiffness from overtreatment and bothy deformity and stiffness from poor treatment (Kamath et al., 2011). Usually they are treated conservatively, and only if the fracture is difficult and unstable, surgery is necessary to fixate the bones with screws, plates and wires internally (Kamath et al., 2011).
