Acetabular template component and method of using same during hip arthrosplasty
First Claim
1. An apparatus for use during surgery on a pelvis of a patient, the apparatus comprising:
- a template having a first surface shaped to mate with an outer surface of an acetabulum of the patient, where the first surface is configured such that the template fits to the acetabulum in a single orientation; and
a directional guide vane attached to the template, where the directional guide vaneprovides a visual indication of a direction in space relative to the pelvis, when the template is fitted to the acetabulum in the single orientation, andis adjustable relative to the template for altering the direction indicated by the directional guide vane, when the template is fitted to the acetabulum in the single orientation.

Abstract
A medical imaging device takes one or more images of the local anatomy of a patient undergoing a surgical procedure. A surface model generator receives the one or more images and generates a 3-D surface model of the patient'"'"'s anatomy. A fabrication device utilizes the 3-D surface model to fabricate a template custom designed to match the surface of the patient'"'"'s anatomy. Attached to the template is a directional guide vane. The fabrication device is configured to create a template and directional guide vane such that, when the template is fitted to the patient'"'"'s anatomy, the directional guide vane points along a predefined orientation relative to the patient'"'"'s anatomy. A physician uses the directional guide vane as a visual guide or cue for installing an implantable prosthetic component during a surgical procedure.

22. An apparatus for use during a surgical operation on a pelvis of a patient, the apparatus comprising:
-
a template having a first surface and a second surface opposite the first surface, the first surface pre-operatively formed to mate with an acetabular rim surface around an acetabulum of the patient, where the first surface is configured such that the template fits to the acetabulum in a single orientation; and a surgical guide attached to the second surface, the surgical guide adjustable relative to the template during the surgical procedure and configured to provide a visual indication in space of determined, patient-specific abduction and anteversion angles for guiding a component into the acetabulum of the patient at the determined, patient-specific abduction and anteversion angles. - View Dependent Claims (23, 24)
