A total hip replacement (total hip arthroplasty or THA) consists of replacing both the acetabulum and the femoral head while hemiarthroplasty generally only replaces the femoral head. Hip replacement is one of the most common orthopaedic operations, though patient satisfaction varies widely.
Hip resurfacing has been developed as a surgical alternative to total hip replacement (THR). The procedure consists of placing a cap (usually made of cobalt-chrome metal), which is hollow and shaped like a mushroom, over the head of the femur while a matching metal cup (similar to what is used with a THR) is placed in the acetabulum ( pelvis ...

Hip resurfacing, sometimes called hip shaving, is preferred over a total hip replacement for elite athletes, Su said, because it preserves more of the femur, uses a metal alloy made of cobalt and ...
Titanium is used from head to toe in biomedical implants. One can find titanium in neurosurgery, bone conduction hearing aids, false eye implants, spinal fusion cages, pacemakers, toe implants, and shoulder/elbow/hip/knee replacements along with many more.
Materials. Some ceramic materials commonly used in joint replacement are alumina (Al 2 O 3 ), zirconia (ZrO 2 ), silica (SiO 2 ), hydroxyapatite (Ca 10 (PO 4) 6 (OH) 2 ), titanium nitride (TiN), silicon nitride (Si 3 N 4 ).
Ti-6Al-7Nb (UNS designation R56700) is an alpha-beta titanium alloy first synthesized in 1977 containing 6% aluminum and 7% niobium. It features high strength and has similar properties as the cytotoxic vanadium containing alloy Ti-6Al-4V. Ti-6Al-7Nb is used as a material for hip prostheses.
For osseointegrated dental implants, metallic, ceramic, and polymeric materials have been used, in particular titanium. To be termed osseointegration the connection between the bone and the implant need not be 100%, and the essence of osseointegration derives more from the stability of the fixation than the degree of contact in histologic terms.
The modified posterior MIS approach to hip resurfacing and total hip arthroplasty (hip replacement) displays a host of advantages to the patient: Less post-operative pain; Less soft tissue damage and pressure on muscle fibres. Shorter hospital stay; Lower blood loss; Smaller incision; Quicker return to work and functional activities
Arthroplasty (literally " [re-]forming of joint ") is an orthopedic surgical procedure where the articular surface of a musculoskeletal joint is replaced, remodeled, or realigned by osteotomy or some other procedure. It is an elective procedure that is done to relieve pain and restore function to the joint after damage by arthritis or some ...
