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.
A total hip replacement consists of replacing both the acetabulum and the femoral head while hemiarthroplasty generally only replaces the femoral head. Hip replacement is currently the most common orthopaedic operation, though patient satisfaction short- and long-term 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 ...
While bone resorption is commonly associated with many diseases or joint problems, the term osteolysis generally refers to a problem common to artificial joint replacements such as total hip replacements, total knee replacements and total shoulder replacements.
Who might need hip replacement surgery? Porizkova's hip issues were caused by developmental hip dysplasia.
DePuy identified reasons for the failure of the hip replacement system as component loosening, component malalignment, infection, fracture of the bone, dislocation, metal sensitivity and pain. Additional complications from the hip replacement system may include increased metal ion levels in the blood, bone staining, necrosis , swelling , nerve ...
If the material is ceramic, it is difficult to form the desired shape, and bone can't reabsorb or replace it due to its high crystallinity. Hydroxyapatite, on the other hand, has shown excellent properties in supporting the adhesion, differentiation, and proliferation of osteogenesis cell since it is both thermodynamically stable and bioactive ...
U.K. manufacturer Morgan Advanced Ceramics (MAC) began manufacturing orthopaedic devices in 1985 and quickly became a recognised supplier of ceramic femoral heads for hip replacements. MAC Bioceramics has the longest clinical history for alumina ceramic materials, manufacturing HIP Vitox® alumina since 1985. [13]
Minimally invasive hip resurfacing (MIS) is a total or partial hip surgery that can be carried out through an incision of less than 10 cm (4 inches) without imparting great forces on the anatomy or compromising component positioning.
Hip dysplasia is an abnormality of the hip joint where the socket portion does not fully cover the ball portion, resulting in an increased risk for joint dislocation. Hip dysplasia may occur at birth or develop in early life. Regardless, it does not typically produce symptoms in babies less than a year old.
