Short Stem Navigation and Optimized Range of Motion
The demand for less invasive procedures and bonesparing hip implants has led to the development of short stem prostheses. Various types of hip prostheses are called short stem, although they are based on different principles. Shortened conventional, short anatomic, double taper type, and neck implants rely on different fixation points in the femur and need to be reviewed individually. Short stem prostheses all have in common that they preserve the greater trochanter and part of the femoral neck, which leads to a curved implantation technique and is well suited for a minimally invasive procedure. The cementless fixed prostheses provide a high primary stability to allow immediate weight bearing (Eingartner 2007).
