Cemented and uncemented orthopaedic implants

An implant can be fixed to the patient's bone in several ways, depending on the quality of the bone, the load exerted on the joint and also on individual surgeons' preferences.

Cemented or uncemented fixing of orthopaedic implants

Coating for uncemented implants

There are two basic methods for fixing implants: cemented, using a polymer to fill the gap between the implant and the bone, and uncemented, using a bioconducting coating on the implant so that the bone can adhere directly to it.

Mechanical anchors such as screws and pegs may also be used to supply the biological fixation.
