Biocompatible cement compositions in a hardened state for filling an orthopaedic cavity and fixating a medical implant in the skeletal bone, by mixing fixation grains (granules) with a biocement slurry or paste, either inside or outside an orthopaedic cavity. A medical implant can be inserted into the grains either before or after the addition of the biocement slurry or paste. The biocompatible cement compositions achieve both high initial fixation strength, as well as a fixation providing long-term stability and biocompatibility, without any negative health effects. The biocompatible cement compositions can suitably be used for filling orthopaedic cavities due to for example osteoporosis, cancer, fractures or other types of bone defects, and can also be used for fixating general orthopaedic and dental implants. |
