Preoperative templating for total hip arthroplasty requires precision and accuracy. The current method of acetate overlays is subject to errors in magnification. Digital radiography permits the use of software programs that calculate the x-ray magnification with precision and then adjust the templates to match the exact magnification. A reproducible set of steps is described that allows a surgeon to preoperatively template in the digital environment.
全髋关节置换术的术前模板制作需要精确性和准确性。目前使用醋酸酯覆盖物的方法存在放大误差。数字放射成像允许使用能精确计算X射线放大率并随后调整模板以匹配精确放大率的软件程序。本文描述了一套可重复的步骤，使外科医生能够在数字环境中进行术前模板制作。
