Open Reduction Internal Fixation techniques often are used in cases involving serious fractures such as comminuted or displaced fractures or, in cases where the bone otherwise would not heal correctly with casting or splinting alone. Risks and complications may include bacterial colonization of the bone, infection, stiffness and loss of range
