US 2017/0360513 A1 · ROBOTIZED SYSTEM FOR FEMOROACETABULAR IMPINGEMENT RESURFACING

Abstract

Systems and methods are described herein for resurfacing bones, and in particular, for detecting and resurfacing one or more femoroacetabular impingements (FAIs). A FAI resurfacing controller may be used to perform this detecting and resurfacing of FAIs. The FAI resurfacing controller may include a bone model generator to receive bone imaging and to generate a model of at least one osteophyte and of a surface of a native bone surrounding the at least one osteophyte. The FAI resurfacing controller may include an osteophyte identifier to set a virtual 3D boundary surface between native bone surface and the at least one osteophyte. The FAI resurfacing controller may include a resurfacing navigator to generate and output a navigation file. The navigation file may include the model with the 3D boundary surface between native bone surface and the at least one osteophyte.

Dependent claims

A femoroacetabular impingement resurfacing system comprising:

a bone model generator to receive a bone imaging data set and generate a resurfacing model based on the bone imaging data set, the resurfacing model including at least one osteophyte and a native bone surface connected to the at least one osteophyte;
an osteophyte identifier to map a virtual 3D boundary surface based on the resurfacing model, the virtual 3D boundary surface identifying an osteophyte virtual boundary located between the native bone surface and the at least one osteophyte;
a resurfacing navigator to generate a navigation file, the navigation file including the resurfacing model and the virtual 3D boundary surface, the navigation file to provide control instructions to resurface the native bone surface to remove the at least one osteophyte;
and
an osteophyte removal device to automatically resurface the native bone surface based on the navigation file.
