NIH Awards Grant to ICT, Inc!!
NIH has awarded a $100,000 Phase I SBIR grant to Industrial Ceramic Technology, Inc. The six month program "Ceramic Composite Research for Total Joint Arthroplasty" will evaluate the wear performance of ceramic-on-ceramic articulating hip components. Tests will be conducted at Loma Linda University Medical Center using a computer controlled hip simulator. The goal of the program is to assess the feasibility of eliminating polyethylene (UHMWPE) and its wear debris problems in joint design. A novel EDMable wear resistant ceramic composite, CRYSTALOY® 2311EDX, developed by ICT, Inc. will be used to fabricate femoral head and cup components.
The wear of and wear debris produced by current implant materials remains a technical barrier to achieving long life prosthetics in total joint arthroplasty. There is a growing consensus that polyethylene (UHMWPE) particle debris is the most biologically active. If this material could be eliminated from joint designs an improvement in performance and longevity may be possible. ICT, Inc. is currently testing an electroconductive ceramic matrix composite (CMC) in femoral head and cups using a full joint hip simulator without UHMWPE components. If successful, CMC would replace UHMWPE components, eliminating the problems of thinning and the destructive osteolytic reaction to wear debris. Wear debris disease from polyethylene components has been identified as a major problem in achieving long life orthopaedic implants.
Conventional ceramic materials, initially alumina and more recently zirconia, have been used in orthopaedic reconstructive surgery for about 25 years. Zirconia ceramics are now known to lose strength with exposure to aqueous environments, reducing long term reliability. Ceramic materials have been of interest in solving these wear problems due to their inherent hardness, high elastic modules, corrosion resistance and abrasion resistance. The availability of new ceramic composite technology now provides an opportunity not previously explored. The CMC to be evaluated for wear against itself has superior properties compared to alumina and zirconia.
