摘要：
Artificial joint prostheses are provided whose outer surfaces include a screw thread which is interrupted by porous-coated columns so as to produce an alternating pattern of threaded columns adjacent to porous-coated columns. The threaded columns provide initial mechanical fixation of the prosthesis to bone and the porous-coated columns provide long-term fixation through bone ingrowth.
