Benefits of technology

[0084]According to some embodiments, a non-transitory computer readable storage medium stores one or more programs, the one or more programs comprising instructions for execution by one or more processors for: receiving image data associated with a joint of a subject; generating a three-dimensional model of at least a portion of the joint of the subject using the image data; identifying at least one region of the joint that deviates from a baseline anatomy by comparing at least a portion of the three-dimensional model to a baseline model;

Problems solved by technology

Joint injuries or conditions such as those of the hip joint or other joints can occur from overuse or over stretching or due to other factors, including genetic factors, and may cause deviation from the baseline anatomy of the joint.
FAI can result in a reduced range of motion, substantial pain and, in some cases, significant deterioration of the hip joint.
In some cases, the FAI may be sufficiently severe as to require surgical intervention, e.g., removal of the bone causing the FAI and repair of any damaged soft tissues.
However, when treating FAI using minimally-invasive arthroscopic techniques, it is generally quite difficult for the physician to determine exactly how much bone should be removed, and whether the shape of the remaining bone has a desired geometry.
In practice, physicians tend to err on the side of caution and remove less bone rather than more bone.
Significantly, under-resection of the pathology is the leading cause of revision hip arthroscopy.
A Lateral Center Edge Angle of between 20-25 degrees is typica

Abstract

A method for visualizing at least one region of a joint that deviates from a baseline anatomy includes receiving image data associated with a joint of a subject, generating a three-dimensional model of at least a portion of the joint using the image data, identifying at least one region of the joint that deviates from the baseline anatomy by comparing the three-dimensional model to a baseline model, generating a measurement of a characteristic of the joint at one or more predefined locations using the three-dimensional model and a coordinate system, and generating a three-dimensional rendering of the model that includes a visual indication of the at least one region of the three-dimensional model that deviates from the baseline so that the region is visually indicated according to degree of deviation, and a representation of the measurement of the characteristic of the joint that is positioned according to the predefined locations.
