CoCr Femoral Head - Metallic femoral head prosthesis

Intended purpose

Hemi and total hip arthroplasties are indicated for the treatment of symptomatic pain and/or functional problems of the hip in patients whose skeleton is mature and only when pain killers and conservative treatment used correctly have failed. The anatomy and structure of the patients articulation will need to be adapted to receive the selected implant(s). The most frequent indications for total or partial hip arthroplasty are: o Degenerative non inflammatory arthropathy (osteoarthritis of the hip) o Inflammatory arthropathy such as rheumatoid arthritis, or post traumatic arthritis o Metabolic arthropathy (chondo calcinosis) o Post Traumatic degenerative arthritis o Avascular necrosis o Congential dysplasia of the hip o Functional repair of a recent trauma (fracture, dislocation) o Revision of a previous failed partial or total arthroplasty o Complications related to peri articular bone tumours
