US 9,956,089 B2 · Prosthesis guide comprising patient-matched features

Abstract

Disclosed herein are systems, devices, and methods for guiding placement, orientation, and fixation of an orthopedic implant. Examples include a surgical guide having a first surface structured to fit within a prosthetic cup, at least one guide hole through the first surface, and an alignment structure having a contour formed from data indicative of the patient anatomy. The contour of the alignment surface is complementary to a portion of the patient anatomy in a unique orientation that aligns the guide hole with tissue suitable for receiving a fastener. The alignment structure preferably includes an arm with a first end coupled to a rim of the guide and a second end coupled to the contour. In certain implementations, the guide includes a plurality of alignment structures. Further disclosed are methods of making and using a surgical guide for aligning an orthopedic implant.

Dependent claims

A method of making a surgical guide for aligning a prosthetic cup, comprising the steps of:

processing imaging data of a portion of a patient's anatomy;
identifying at least one suitable location on the patient's anatomy for placement of a fastener;
identifying an alignment surface on the patient's anatomy;
forming a first surface of the guide structured to fit within a prosthetic cup;
forming an alignment structure on the guide, the alignment structure having a patient-matched surface that is contoured to align the prosthetic cup relative to the alignment surface in a single, unique position and orientation;
and
forming a guide hole through the first surface of the guide, wherein the guide hole is aligned with a fastener hole in the prosthetic cup to create a common through hole;
and
wherein the alignment structure is configured to extend beyond an outer surface of the prosthetic cup to interface with the patient's anatomy in such a manner that the common through hole aligns with the identified suitable location on the patient's anatomy when the guide is positioned in the single, unique position and orientation.
