The application of titanium alloy wires for the reattachment of the greater trochanter in total hip arthroplasty.
We developed a new fixing method using titanium alloy wires in order to facilitate the attachment of the greater trochanter in total hip arthroplasty.  This wire is composed of Ti-3Al-2.5V by weight. According to the fatigue test in vitro, the titanium alloy wire had better fatigue properties than Ortron 90 wire of the same diameter.  In experiments in vivo, both titanium alloy wires and SUS-316L wires were used for the reattachment of the greater trochanter of dogs, and the titanium alloy wires showed better biocompatibility than the latter. Thus, titanium alloy wires seem applicable for the reattachment of the greater trochanter in human total hip arthroplasty.
