1 Maintenance of Proximal Cortical Bone with Use of a Less Stiff Femoral Component in Hemiarthroplasty of the Hip without Cement. An Investigation in a Canine Model at Six Months and Two Years* by T.

2 Fig. 1 Photograph of the less stiff (left) and stiffer (right) femoral stems, which had the same shape and were both circumferentially porous-coated along the entire length, except for the distal five millimeters.
