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. The main reason why titanium is often used in the body is due to titanium's biocompatibility and, with surface modifications, bioactive surface.
The analysis of 402,051 hip replacements showed that 6.2% of metal-on-metal hip implants had failed within five years, compared to 1.7% of metal-on-plastic and 2.3% of ceramic-on-ceramic hip implants. Each 1 mm (0.039 in) increase in head size of metal-on-metal hip implants was associated with a 2% increase in failure rate. [60]
The 2010 DePuy Hip Replacement Recall was instituted when DePuy Orthopaedics, Inc., a division of Johnson & Johnson, recalled its ASR XL Acetabular metal-on-metal hip replacement system on August 24, 2010. [1][2]
Metallosis. Metallosis is the medical condition involving deposition and build-up of metal debris in the soft tissues of the body. [1] Metallosis has been known to occur when metallic components in medical implants, specifically joint replacements, abrade against one another. [1] Metallosis has also been observed in some patients either ...
Joint replacement is a procedure of orthopedic surgery known also as arthroplasty, in which an arthritic or dysfunctional joint surface is replaced with an orthopedic prosthesis. Joint replacement is considered as a treatment when severe joint pain or dysfunction is not alleviated by less-invasive therapies. Joint replacement surgery is often ...
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.
An osseointegrated implant is a type of implant defined as "an endosteal implant containing pores into which osteoblasts and supporting connective tissue can migrate". [2] Applied to oral implantology, this refers to bone grown right up to the implant surface without interposed soft tissue layer. No scar tissue, cartilage or ligament fibers are ...
TAV-ELI is the most commonly used medical implant-grade titanium alloy. [25] [27] Due to its excellent biocompatibility, corrosion resistance, fatigue resistance, and low modulus of elasticity, which closely matches human bone, [28] TAV-ELI is the most commonly used medical implant-grade titanium alloy. [29]
