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.
Examples of prostheses from the 1990s: Examples, some of which were developed at the Redhill Group of Hospitals and Dorking Hospital, include a ringed titanium hip prosthesis with a screw stem and porous cup, a modular hip prosthesis with a textured femoral stem to aid bone grafting (material unspecified), two Thompson-type prostheses made of ...
For example, a hip joint that is affected by osteoarthritis may be replaced entirely (total hip arthroplasty) with a prosthetic hip. This procedure involves replacing both the acetabulum (hip socket) and the head and neck of the femur .
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...
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 ...
An orthopedic implant is a medical device manufactured to replace a missing joint or bone, or to support a damaged bone. [1] The medical implant is mainly fabricated using stainless steel and titanium alloys for strength and the plastic coating that is done on it acts as an artificial cartilage. [2]
A titanium hip prosthesis, with a ceramic head and polyethylene acetabular cup. Ceramics are now commonly used in the medical fields as dental and bone implants. [8] [9] Surgical cermets are used regularly. Joint replacements are commonly coated with bioceramic materials to reduce wear and inflammatory response.
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.
Bone cement is considered a reliable anchorage material with its ease of use in clinical practice and particularly because of its proven long survival rate with cemented-in prostheses. Hip and knee registers for artificial joint replacements such as those in Sweden and Norway [2] clearly demonstrate the advantages of cemented-in anchorage.
Dynamic hip screw (DHS) or Sliding Screw Fixation is a type of orthopaedic implant designed for fixation of certain types of hip fractures which allows controlled dynamic sliding of the femoral head component along the construct.
