The present invention relates to a combined fixation bone implant consisting on a (metallic or non-metallic) implant which, due to its geometry, allows its fixation to the bone tissue in two different and simultaneous ways. In view of its characteristics, it allows that part of its superficial area (coated with any type of material or structure that may stimulate the adhesion or bone integration of the bone tissue) remains in direct contact with the bone tissue and the other part is fixed through the bone cement between the implant and the bone tissue. The process of the implantation on the bone, as well as the retrieval of the implant in case of revision (replacement), minimises the bone loss.
