Basing and clinical aspects of new design endoprosthesis with sapphire pair of friction for patients with hip joint pathology
The authors conducted experimental studies of the tribological and strength characteristics of various materials used in friction pairs hip arthroplasty. The results showed that among the investigated single crystal sapphire material had very high strength, biologically inert, electroneutrality, and hinge "Sapphire – Sapphire," in a liquid medium had the lowest coefficient of friction. It is possible to use this material in the hip joint, and conduct their clinical trials with good results surgery.
