A dynamic compression plate (DCP) is a metallic plate used in orthopedics for internal fixation of bone,[1] typically after fractures. As the name implies, it is designed to exert dynamic pressure between the bone fragments to be transfixed. Dynamic compression is achieved either by attaching a tension device to a plate or by using a special dynamic compression plate. However, compression plating requires a longer surgical incision to allow insertion of the tension device and the possibility of refracture after the plate is removed. A neutralization plate is used to bridge a comminuted fracture; it also transmits bending or torsional forces from the proximal to the distal fragment. Plates used for buttressing prevent collapse by supporting an area of thin cortex or cancellous bone graft.[citation needed]
When plates are used, atrophy of the bone beneath the plate may predispose the bone to fracture. After removal of plates, fractures may occur through the screw holes.
