New Large Diameter Ceramic Bearing Offers Better Stability For Hip Replacements
Morgan Advanced Ceramics (MAC) has extended its range of HIP Vitox® alumina ceramic femoral heads and acetabular cups for use in hip replacement surgery with the addition of a new 36mm ceramic-on-ceramic system. The new larger size is offered in response to increasing demand from customers for larger diameter products for better joint stability.
Recurrent dislocation can be a problem for some people following hip replacement surgery. Research is increasingly demonstrating that larger femoral heads reduce the likelihood of dislocation by providing a more stable joint. The addition of the 36mm product to the MAC range offers surgeons all the durability advantages of the HIP Vitox® alumina material, in a large diameter. Future developments underway utilising MAC's flexible manufacturing process will allow scope for products up to 60mm in diameter.
The larger products offer greater system strength than smaller diameter products, reducing the possibility of product fracture even further. They also feature a larger range of offsets to ±5mm, where existing 28mm products have only allowed ±3.5mm. This gives the surgeon more options and greater flexibility during the operating procedure.
MAC’s HIP Vitox® alumina is a purpose-developed bioceramic material that exhibits exceptionally low wear rates compared to metal or polyethylene. It can be used in alumina on alumina ceramic systems or in conjunction with a polyethylene acetabular cup.
The newly extended standard 12/14 range of HIP Vitox® alumina femoral heads includes diameters from 28mm to 36mm and a range of taper lock cups to complement them.
