The sliding screw plate (dynamic compression screw, dynamic hip screw) may be used to treat intertrochanteric fractures as well as other injuries. This device consists of a lag screw and a side plate with a barrel. The sliding screw telescopes and provides fixation while allowing impaction to occur at the fracture during healing and weight bearing. Among the complications of sliding screw plate fixation are "cutting out" of the nail, penetration of the screw into the joint, bending or breaking of the nail, and disengagement of the screw from the barrel and even protrusion of the screw into the vertebrae.
