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.

Claim (Index 1):
A method of designing a patient-specific guide for resecting a socket joint of a patient comprising:\n obtaining three-dimensional image data of the socket joint; determining from the obtained image data an axis of rotation of the socket joint; and constructing a three-dimensional model of the patient-specific guide from the obtained image data and determined axis of rotation, the three-dimensional model of the patient-specific guide having a superior surface shaped to substantially match an articular surface of the socket joint, the superior surface defining an extension portion shaped to substantially match the shape of an anatomical feature associated with the socket joint and a guide slot having a longitudinal axis coaxial with the determined axis of rotation, wherein the extension portion is shaped such that when the extension portion engages the anatomical feature, the guide is located in a preoperatively planned position and orientation with respect to the socket joint.
