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.

Abstract: A method for displaying graphical indications associated with a joint includes: 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; generating at least one measurement of a characteristic of the joint at one or more predefined locations using the three-dimensional model and a coordinate system; displaying a spectrum bar graph that comprises at least one representation of the at least one measurement of the characteristic of the joint; determining a pathology associated with the joint based on the at least one measurement of the characteristic of the joint; and displaying at least one graphical indication indicating the pathology associated with the joint.

Abstract: A method for hip distraction includes positioning a patient on a slide-resisting pad placed on a surgical table; tilting the surgical table so that the patient is in a first degree of inclination; applying a distraction force to a leg of the patient while the patient is in the first degree of inclination so that a hip joint of the patient is distracted, wherein the distraction force is opposed by a combination of a slide-resisting friction force provided by the slide-resisting pad and a gravitational force attributable to the first degree of inclination; reducing the tilt of the surgical table in accordance with a reduction of the distraction force over time so that the patient is in a second degree of inclination; and performing at least a portion of a surgical procedure on the distracted hip joint while the patient is in the second degree of inclination.

Abstract: A method for hip distraction includes positioning a patient on a patient pad placed on a surgical table; and applying a distraction force to a leg of the patient that is sufficient to distract a hip joint of the patient, wherein the distraction force is opposed by a slide-resisting friction force provided by the patient pad and the patient pad is sufficiently stiff to resist bunching while providing the slide-resisting friction force.
