Technical aspects of cementless total hip arthroplasty.
The technique of cementless total hip arthroplasty (THA) places many demands on the surgeon, who must understand the rationale of the prosthetic design to take full advantage of its features. In addition, the surgeon must be able to gauge the quality of the available bone either by preoperative roentgenographic examination or by intraoperative assessment or both. The surgeon must then choose the prosthesis that will predictably fit the individual conditions. Proper instrumentation, practice in a workshop environment, prophylactic wiring of the femur, and postimplantation testing of the prosthesis are important to achieve lasting results of cementless THA.
