摘要：
A method of creating a patient specific instrument (PSI) for use in knee replacement surgery is described which includes performing at least two X-ray scans of a bone, each of the X-ray scans being taken from different angular positions, generating a digital bone model of the bone based solely on the X-ray scans, planning the PSI based on the digital bone model, including determining locations for one or more anchor points on the PSI which are adapted to abut a surface of the bone, the determined locations of the anchor points being disposed on the PSI at locations corresponding to areas of expected high accuracy on the digital bone model generated by the X-ray scans. The areas of expected high accuracy include at least a peripheral bone contour in at least one of the angular position of the X-ray scans. A suite of such PSI instruments is also described.

描述了一种用于在膝关节置换手术中使用创建患者特异性器械（PSI）的方法，该方法包括：执行一个骨中的至少两个X射线扫描时，每个X射线扫描被从不同的角度位置拍摄，生成数字 在X射线扫描仅基于骨，规划基于数字骨模型的PSI，包括用于一个或多个锚点对PSI哪些是angepasst以邻接骨的表面确定性采矿位置，确定性开采地点的骨模型 被以对应于由所述X射线扫描产生的数字骨模型预期高精度的区位置的PSI设置在所述锚点。 预期的高精确度的领域包括在X射线扫描的角位置中的至少一个的至少一个周边骨轮廓。 器械的套件检查被如此描述PSI。
