Abstrakt		In a normal hip joint the stresses of the acetabulum are transmitted to the distal femur through the proximal femur, containing only cancellous bone. Consequently, the structure of cancellous bone must be resistant to fracture. This observation has led to the development of a completely new total hip prosthesis, called the trabecularly oriented prosthesis. The entire system requires no use of cement and is fixed to cancellous bone in the proximal femur and not in the femur canal. The first component to be developed was the acetabulum, i.e. the cup. Ideally, the cup should have a concave semi-spherical outline, covered by numerous fine needles pointing in the direction of transmitted stresses. For technical reasons the needles in the cup are thicker than ideal, of steplike outline and of unequal length, resulting in an irregular shape of the cup. The femoral part was developed a few years later.
