[Experimental study on the bone cement-precoated implant in arthroplasty].

ABSTRACT

Canine hip joints, in vitro and in vivo, were used for arthroplasty one side was replaced by a bone cement-precoated femoral head prosthesis and the other side by a non-cement-precoated one. Results showed that the interfacial shearing strength between both the implant-cement and the cement-bone interfaces of the cement-precoated ones was obviously stronger than that of the non-cement-precoated ones. Thus, the stability of the prosthesis was remarkably increased in the former than the later.
