SYSTEM AND METHOD FOR EVALUATING PATIENT DATA
A method of extracting and displaying postural measurements from patient data includes retrieving, by a processor of a computing device, the patient data from memory. The patient data includes a geometric mesh representation of a patient, including a plurality of data points corresponding to spatial coordinates of a plurality of vertices in three dimensions. The method also includes determining, by the processor, a reference geometry along the geometric mesh representation in a fixed position with respect to the spatial coordinates; determining, by the processor, a landmark corresponding to one of skeletal or soft tissue anatomy for the patient; and determining, by the processor, a postural deviation of a body portion of the patient by comparing the reference geometry and the landmark. The method further includes displaying, by a display of the computing device, a graphical user interface indicating a characteristic related to the postural deviation
APPARATUS AND METHODS FOR USE WITH SKELETAL PROCEDURES
Method and apparatus are provided for use with a procedure in which interventions are performed with respect to at least first and second vertebrae of a spine of a subject. Imaging data of the subject's spine is acquired using an imaging device. At least one computer processor is used to generate, upon a display, a spinal roadmap image of at least a portion of the spine that contains the first and second vertebra, automatically label vertebra within the spinal roadmap image, determine that an intervention has been performed with respect to the first vertebra, such that an appearance of the first vertebra has changed, and automatically update the spinal roadmap to reflect the change in the appearance of the first vertebra, such that the updated spinal roadmap is displayed while the intervention is performed with respect to the second vertebra. Other applications are also described.
GLOBAL BALANCE USING DYNAMIC MOTION ANALYSIS
An exemplary method of determining a surgical spinal correction for a subject using analysis of motion capture images of the subject, which uses the steps of obtaining pre-operative three-dimensional images of a spinal region, obtaining a pre-operative time sequenced set of images of the subject during a movement progression of said subject, calculating in a plurality of the motion capture images, alignment parameters relating to upper and lower body regions of the subject, and determining if any of the calculated alignment parameters are outside their predetermined acceptable ranges in one or more of the images, iteratively adjusting anatomical elements in three-dimensional images until all of the calculated alignment parameters are within their predetermined acceptable ranges; and adjusting spinal anatomy in the three-dimensional images according to the degree of adjustment of spinal parameters in the motion capture images to determine a surgical spinal correction.
