Abstract
Certain systems, methods, and devices described herein are configured to dynamically model a patient area for surgery and/or other treatment, dynamically identify one or more features and/or characteristics thereon such as the length and/or elasticity of the posterior longitudinal ligament (PLL), dynamically allow modification of the model, dynamically limit and/or assist in modification of the model, and/or dynamically generate guidelines for generation of patient-specific implants and/or treatment kits for a specific patient.
Claims18
A computer-implemented method for producing a patient-specific spinal implant, the method comprising, by a computer system comprising a computer processor and an electronic storage medium:
- receiving, from a medical imaging system, one or more pre-operative images of a spine of a patient in each of a plurality of postures;
- displaying, on a graphical user interface, at least one image of the patient in each posture of the plurality of postures;
- for each posture, determining a length of a posterior longitudinal ligament of the spine based on the corresponding one or more displayed images by receiving, through the graphical user interface, user input indicating a path of the posterior longitudinal ligament in each displayed image;
- determining a value for ligament elasticity of the posterior longitudinal ligament based on a variance among the determined lengths of the posterior longitudinal ligament for each posture;
- determining a recommended limit of correction of the spine based at least in part on one or more of the determined lengths and the determined value for ligament elasticity of the posterior longitudinal ligament, such that a correction does not cause the posterior longitudinal ligament to exceed an elasticity threshold;
- receiving, through the graphical user interface, user selection of a vertebra for modification;
- receiving, through the graphical user interface, user input representing one or more proposed modifications to the selected vertebra, the one or more modifications comprising displacements or rotations of the selected vertebra;
- and
- in response to the one or more proposed modifications to the selected vertebra being within the determined recommended limit of correction of the spine, recommending one or more spinal implants based on the one or more proposed modifications.
A system for producing a patient-specific spinal implant, the system comprising:
- one or more computer readable storage devices configured to store a plurality of computer executable instructions;
- and
- one or more hardware computer processors in communication with the one or more computer readable storage devices and configured to execute the plurality of computer executable instructions, causing the system to:
- receive, from a medical imaging system, one or more pre-operative images of a spine of a patient in each of a plurality of postures;
- display, on a graphical user interface, at least one image of the patient in each posture of the plurality of postures;
- for each posture, determine a length of a posterior longitudinal ligament of the spine based on the corresponding one or more displayed images by receiving, through the graphical user interface, user input indicating a path of the posterior longitudinal ligament in each displayed image;
- determine a value for ligament elasticity of the posterior longitudinal ligament based on a variance among the determined lengths of the posterior longitudinal ligament for each posture;
- determine a recommended limit of correction of the spine based at least in part on one or more of the determined lengths and the determined value for ligament elasticity of the posterior longitudinal ligament, such that a correction does not cause the posterior longitudinal ligament to exceed an elasticity threshold;
- receive, through the graphical user interface, user selection of a vertebra for modification;
- receive, through the graphical user interface, user input representing one or more proposed modifications to the selected vertebra, the one or more modifications comprising displacements or rotations of the selected vertebra;
- and
- in response to the one or more proposed modifications to the selected vertebra being within the determined recommended limit of correction of the spine, recommend one or more spinal implants based on the one or more proposed modifications.
