Abstract

A prosthetic device, method for planning bone removal, and a robotic system for implantation of a prosthetic device in bone are disclosed. The prosthetic device can include a body portion for attachment to a bone, wherein the body portion includes an implantation surface configured to face the bone upon implantation, and a constraint structure. The prosthetic device, method, and robotic system can be configured to cause the constraint structure and bone to interact so as to constrain the prosthetic device in the bone.

Description

CROSS-REFERENCE TO RELATED PATENT APPLICATIONS

[0001] This application claims priority to U.S. Provisional Patent Application Ser. No. 61 / 208,451, filed on Feb. 24, 2009, which is hereby incorporated by reference in its entirety.BACKGROUND OF THE INVENTION

[0002] 1. Field of Invention

[0003] The present invention relates to a prosthetic device for implantation in bone, methods of planning bone removal for implantation of a prosthetic device in bone, and robotic systems for preparing a bone to receive a prosthetic device.

[0004] 2. Description of Related Art

[0005] Conventional prosthetic implantation techniques involve resecting a pocket of material from a bone to provide a void or pocket within the bone that receives a prosthetic device. After resection of bone material is complete, the prosthetic device is implanted within the pocket. The prosthetic device is typically secured in place with bone cement.

[0006] Using the conventional techniques, undesired movement of the prosthetic device rela...
