Embodiment Construction

[0042] Disclosed herein are systems, devices, and methods for generating surgical designs to modify abnormal bone by using a universal normal bone model. Embodiments described herein can help improve efficacy and reliability in osteoplastic surgery planning, such as removal of excess bone from a femoral neck where cam impingement exists. The methods and devices described herein are also applicable to the design of surgery on diseased bone under various other conditions.

[0043] figure 1 is a block diagram illustrating an example of a system 100 for planning surgery on abnormal bone. The system 100 may include a model receiver module 110 , an input interface 120 and a surgical design module 130 . System 100 may also include memory circuitry 140 and controller circuitry 150 . Optionally, system 100 may include a communication interface 160 . In one example, the system 100 may generate instructions for operating a surgical tool (eg, a surgical navigation system or a medical ...

Abstract

Systems and methods for generating a surgical plan for altering an abnormal bone using a generic normal bone model are discussed. For example, a system for planning a surgery on an abnormal bone can include a model receiver module (110) configured to receive a generic normal bone model (440). The generic normal bone model (440) can include a data set representing a normal bone having an anatomical origin comparable to the abnormal bone. An input interface (120) can receive an abnormal bone representation (430) including a data set representing the abnormal bone. A surgical planning module (130) can include a registration module (131) configured to register the generic normal bone model to the abnormal bone representation by creating a registered generic model. A surgical plan formation module (132) can be configured to identify one or more abnormal regions (452) of the abnormal bone (430) using the registered generic model.

Description

[0001] related application [0002] This application claims priority to US Provisional Patent Application Serial No. 61 / 779,805, filed March 13, 2013, which is hereby incorporated by reference in its entirety. technical field [0003] This document relates generally to computer-assisted orthopedic surgery, and more particularly to systems and methods for generating surgical plans for modifying abnormal bone using a generic normal bone model. Background technique [0004] The use of computers, robotics and imaging to assist in orthopedic surgery is well known in the art. There has been a great deal of research and development into computer-aided navigation and robotic systems for guiding surgical procedures. For example, Precision Freehand Sculptor (PFS) employs robotic surgical systems to assist surgery in precisely cutting prosthesis into the desired shape. In interventions such as total hip replacement, computer-aided surgical techniques have been used to improve the acc...
