摘要： A patient-specific acetabular guide can be used for preparing an acetabulum of a patient to receive an acetabular implant. The acetabular guide includes a patient-specific engagement surface designed to be complementary and mateable with a corresponding surface of the patient's pelvic anatomy. The acetabular guide is designed during a pre-operative plan for the patient by a three-dimensional reconstruction of the anatomy of the patient using two-dimensional medical images. The patient-specific engagement surface has a first portion mateable with a portion of the acetabulum of the patient. The acetabular guide includes a guiding element that extends from the acetabular guide opposite to the first portion of engagement surface. The guiding element defines a bore designed to be oriented along an alignment axis for an acetabular implant when the acetabular guide is engaged to the acetabulum.

摘要翻译： 患者特异性髋臼引导件可用于制备患者的髋臼以接收髋臼植入物。 髋臼引导件包括设计成与患者骨盆解剖结构的相应表面互补并可配合的患者特异性接合表面。 通过使用二维医学图像对患者的解剖结构进行三维重建，在患者的术前计划中设计髋臼引导件。 患者特异性接合表面具有与患者的髋臼的一部分配合的第一部分。 髋臼引导件包括从髋臼引导件与接合表面的第一部分相对延伸的引导元件。 引导元件限定了当髋臼导向器与髋臼接合时设计成沿着对准轴线对准髋臼植入物的孔。
