Abstract

Systems, methods, and devices are described for providing orthopedic implant augments having fastener locking mechanisms. The augments include a surface for mating with an implant component and a surface for interfacing with a patient's bone. The fastener locking mechanisms are aligned such that the augment may be locked in a variety of orientations while maintaining close contact with both an implant and a patient's bone. The alignment of the locking mechanisms provides variability and adjustability to the augment to address a variety of bone anatomies and requirements.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application No. 61 / 567,971, filed December 7, 2011, which is hereby incorporated by reference in its entirety. Background technique [0003] Joints often undergo degenerative changes for various reasons. When degeneration becomes severe or irreversible, it may become necessary to replace the natural joint with a prosthetic joint. Degenerative disease or injury may require replacement of all or a portion of a patient's joint using a composite material, typically metal, ceramic or polymeric material. Artificial implants made from these materials, including hip implants, shoulder implants, and knee implants, are widely used in orthopedic surgery to strengthen or replace deteriorating joints. [0004] In primary replacement surgery, the patient's natural joint is replaced with a prosthetic implant. The implant is designed to be integrated with the patient's bon...
