<unk> <unk>  <unk>  or Sliding<unk>  Fixation is a type of orthopaedic implant designed for fixation of certain types of<unk>  fractures which allows controlled<unk>  sliding of the femoral head component along the construct. It is the most commonly used implant for extracapsular fractures of the<unk> , which are common in older osteoporotic patients. There are 3 components of a<unk> , including a lag<unk>  (inserted into the neck of the femur), a sideplate and several cortical<unk> s (fixated into the proximal femoral shaft). The idea behind the<unk>  compression is that the femoral head component is allowed to move along one plane; since bone responds to<unk>  stresses, the native femur may undergo primary healing: cells join along boundaries, resulting in a robust joint requiring no remodeling.
