The internal structure of the arthrosic and normal femoral heads are grossly different although both are roughly circular. In particular bone is destroyed or defective superolaterally in the former. The compressive strength of the femoral head depends upon the medial trabecular system which runs through the head at approximately 20 degrees to the vertical i.e. the plane of the resultant of the major loads borne by the hip. Ideally a femoral resurfacing prosthesis should be placed in this axis… CONTINUE READING
