    • Disclosed herein are systems, devices, and methods for guiding placement, orientation, and fixation of an orthopedic implant. Examples include a surgical guide having a first surface structured to fit within a prosthetic cup, at least one guide hole through the first surface, and an alignment structure having a contour formed from data indicative of the patient anatomy. The contour of the alignment surface is complementary to a portion of the patient anatomy in a unique orientation that aligns the guide hole with tissue suitable for receiving a fastener. The alignment structure preferably includes an arm with a first end coupled to a rim of the guide and a second end coupled to the contour. In certain implementations, the guide includes a plurality of alignment structures. Further disclosed are methods of making and using a surgical guide for aligning an orthopedic implant.
    • 本文公开了用于引导整形外科植入物的放置,取向和固定的系统,装置和方法。 实例包括具有构造成装配在假体杯内的第一表面,穿过第一表面的至少一个引导孔和具有由指示患者解剖结构的数据形成的轮廓的对准结构的手术引导件。 对准表面的轮廓与患者解剖结构的一部分互补,其方式是将引导孔与适于接收紧固件的组织对准。 对准结构优选地包括臂,其具有联接到引导件的边缘的第一端和联接到轮廓的第二端。 在某些实施方案中,引导件包括多个对准结构。 还公开了制造和使用用于对准整形外科植入物的外科手术引导件的方法。
