This study was designed to determine if a porous polytetrafluoroethylene-graphite coating could furnish long-term stabilization of total hip prostheses. Prostheses were surgically implanted in 12 mature goats, which were observed postoperatively for as long as 1 year. Effective stabilization occurred in only 4 animals. Poor results in the other animals were attributed to lack of stabilization of the prostheses following initial implantation, which allowed movement at the interface between bone and polytetrafluoroethylene-graphite.
本研究旨在确定多孔聚四氟乙烯 - 石墨涂层能否为全髋关节假体提供长期稳定性。将假体通过手术植入12只成年山羊体内，并对其进行长达1年的术后观察。仅4只动物实现了有效的稳定。其他动物效果不佳归因于初始植入后假体缺乏稳定性，这使得骨与聚四氟乙烯 - 石墨之间的界面发生了移动。
