The term ‘orthopaedic implants’ covers a variety of artificial instruments that are utilized for replacing joints such as hips, knees, and so on in the body. These implants are now being increasingly used to replace damaged and/or arthritic joints. Nowadays, there are higher demands on manufacturers develop more durable implants because of the wider utilization of implants in younger patients and the increasing lifespan of individuals.
In the case of hip implants, the femoral head and cup’s form characteristics are vital for its load bearing capacity. Failure in hip joints is mostly because of the wear of the implants and wear particles generated. For example, osteolysis is the most common factor for femoral bone loss. This is attributed to various factors, from particulate debris to foreign body reaction and polymeric debris. Avoiding wear in hip joints is vital for successful hip implants. This need results in higher tolerances on surface finishes of the implants themselves. The Manufacture of hip joint is controlled by standards such as ISO 7206.
Requirement for knee implants are analogous to hip implants and need optimum surface finish and form characteristics to assure required performance standards. Taylor Hobson provides orthopaedic implant developers a variety of surface finish measurement solutions that assist in enhancing the performance and quality of the implants.
