Abstract
Disclosed herein are systems and methods for performing total hip arthroplasty with patient-specific guides Pre-operative images of a pelvic region of a patient are taken in order to predefine the structure of the guides and corresponding implants. From the obtained image data an insertional vector for implanting an acetabular implant or component into an acetabulum of the patient is determined, wherein the insertional vector is coaxial with a polar axis of the acetabular component. Also from the obtained image data, a superior surface of the guides and implants can be shaped to match the acetabulum of the patient. A nub portion extending outwardly from the superior surface of the guides and implants is shaped to substantially match the shape of a fovea of the acetabulum. A guide portion of the guides forming a slot has a longitudinal axis coaxial with the determined insertional vector of a corresponding acetabular component.
