The majority of orthopedists today prefer to treat patients aged over 60 years old by a hybrid arthroplasty, implanting a cementless cup combined with a cemented stem [7, 22, 30]. Cementless fixation of the stem can also be considered in younger and active patients. Improvements in cementation technique have undoubtedly led to a significant improvement in the long-term fixation of implants [3]. The refined cementation technique comprises in particular the cleaning of the medullary cavity by rinsing and drying, and the pressurization of the bone cement. Various authors [23, 25] have pointed out the importance of the prosthesis stem being completely surrounded by a mantle of cement and the danger of direct contact between metal and bone [8]. |
