Abstract

Systems, devices, and methods for accurately aligning a reference pin within a patient's acetabulum are provided. A patient's acetabular anatomy is imaged and modeled using a computer modeling approach to identify landmarks on the patient's acetabulum. A coordinate system is applied to the anatomical model, and a desired implant axis is defined based on the applied coordinate system. A guide device is created with one or more guide passages aligned with the desired implant axis for accurately placing an acetabular reference pin. The guide devices are patient-matched to an individual patient's anatomy and are expandable to provide an adequate grip on the acetabulum during pin placement. A reference pin fixed into the acetabulum provides a reference axis that corresponds to the desired implant access and can be used for alignment of tools and implants in the acetabulum.
