Hybrid fixation means that the one component of total hip arthroplasty is fixed without bone cement and the other component is fixed with bone cement.  In the early days of total hip replacement, both the cup and the stem were cemented into place. The trend later moved to cement-less fixation of the cup and with stem being cemented this is called a “hybrid” fixation. Hybrid fixation in total hip arthroplasty means that the cup is fixed without cement while the femoral component is cemented into position. Currently, I very rarely use cement for component fixation in total hip arthroplasty. Most of my total hip cases are non-cemented on both sides.
