Computer-Assisted Hip and Knee Arthroplasty :Navigation and Robotic Systems

In the mid-1980s, cementless femoral components (not requiring bone cement to join the prosthesis to the bone) were introduced for hip arthroplasty. Problems associated with cementless femoral components included postoperative thigh pain, intraoperative fracture and failure of bony ingrowth. It was subsequently realized that, not only should the implant fit the femur well, but the bone should also be shaped accurately to fit the implant. In addition, the surgical instruments in use at that time were from the era when only cemented components were used. These instruments create a rough, irregular surface that is ideal for cement, but inaccurate for cementless applications. The inaccuracies created gaps at the implant to bone junction that could lead to instability and decreased bony ingrowth.

je pensais à 'interposition osseuse' pour 'bony ingrowth' mais que mettre devant ? merci !
