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.

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Patent Application No. 61 / 493,260, filed June 3, 2011, and U.S. Provisional Patent Application No. 61 / 561,619, filed November 18, 2011, which are incorporated herein by reference. incorporated herein in its entirety. technical field [0003] The present disclosure relates generally to surgery, and more particularly to orthopedic instruments for use in bone repair. Background technique [0004] Joints experience degenerative changes for a number of reasons. When joint degeneration becomes increased or irreversible, replacement of the natural joint with a prosthetic joint becomes necessary. Artificial implants including hip, shoulder and knee joints are widely used in orthopedic surgery. Specifically, hip prostheses are common. The human hip joint functions mechanically as a ball and socket joint, in which the spherical head of the femur is positioned within th...

AI Technical Summary

Problems solved by technology

[0006] In joint repair and orthopedic surgery, the tissue structure surrounding the patient's joint is severely degenerated or damaged to a state where accurate guidance of surgical instruments and correct placement of implants becomes challenging, which can adversely affect surgical outcomes

For example, a surgeon may not be able to locate and identify tissue reference points where surgical procedures need to be performed
