Электрохимическое исследование пористой титановой вставки эндопротеза тазобедренного сустава

Электрохимическое исследование пористой титановой вставки эндопротеза тазобедренного сустава

Abstract

Бесцементные титановые эндопротезы тазобедренного сустава находят широкое применение в лечебной практике. Использование специальных пористых вставок в проксимальной части ножки протеза и нанесение на поверхность эндопротеза слоя диоксида титана обеспечивает эффективную остеоинтеграцию имплантата. С целью поиска путей дальнейшего совершенствования протезов данного типа, в настоящем исследовании обосновано применение методов электрохимии для диагностики функциональных свойств диоксид-титановых покрытий. Установлено, что двукратное нанесение диоксид-титанового покрытия на поверхность пористых вставок титановых эндопротезов системы SLPS позволяет значительно снизить скорость анодных процессов и улучшить защитные свойства покрытия.

Cementless titanium hip endoprostheses are widespread in clinical practice. Usage of the special titanium porous inserts in the proximal part of the prosthetic stem and coating of the implants with titanium dioxide layer provides enhanced osseointegration of the implants. In order to improve the quality of the implants application of the electrochemical methods for diagnostics of the titanium dioxide layer functional properties is recommended. Double coating of porous titanium insert’s surface of SLPS hip implants with titanium-dioxide allows to significantly decrease the speed of anodic processes and improve protective qualities of the covering layer.
