US 10,292,770 B2 · Systems, methods, and devices for developing patient-specific spinal treatments, operations, and procedures

Abstract

The disclosure herein relate to systems, methods, and devices for developing patient-specific spinal treatments, operations, and procedures. In some embodiments, systems, methods, and devices described herein for developing patient-specific spinal treatments, operations, and procedures can comprise an iterative virtuous cycle. The iterative virtuous cycle can further comprise pre-operative, intra-operative, and post-operative techniques or processes. For example, the iterative virtuous cycle can comprise imaging analysis, case simulation, implant production, case support, data collection, machine learning, and/or predictive modeling. One or more techniques or processes of the iterative virtuous cycle can be repeated.

A system for developing one or more spinal implants for a patient, 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 in order to cause the system to:
access one or more medical images of a spine of a patient;
simulate, on the one or more medical images, implantation of a spinal rod to a vertebral segment of interest, wherein the simulation of implantation of the spinal rod further comprises:
identifying one or more reference points along the vertebral segment of interest;
and
rotating one or more portions of the one or more medical images around the identified one or more reference points to obtain a desired surgical output curvature of the spine of the patient;
determine, based at least in part on the simulation of implantation of the spinal rod, one or more dimensions of a patient-specific spinal rod for the vertebral segment of interest, wherein the one or more dimensions of the patient-specific spinal rod comprises a diameter and curvature thereof;
generate spinal rod manufacturing or selection data instructions, based at least in part on the determined one or more dimensions of the patient-specific spinal rod, for use by a spinal rod manufacturing or selection apparatus for producing or selecting the patient-specific spinal rod for the vertebral segment of interest;
determine, from the one or more medical images, a length of an anterior longitudinal ligament for the vertebral segment of interest and a length of a posterior longitudinal ligament for the vertebral segment of interest;
determine, from the one or more medical images, a length of an anterior curve for the vertebral segment of interest and a length of a posterior curve for the vertebral segment of interest;
simulate, on the one or more medical images, implantation of one or more cages to one or more intervertebral spaces within the vertebral segment of interest, wherein the simulation of implantation of the one or more cages further comprises:
increasing a posterior height of each of the one or more cages until the length of the posterior curve substantially matches or does not exceed the length of the posterior longitudinal ligament;
and
increasing lordosis of each of the one or more cages while maintaining the length of the anterior curve shorter than the anterior longitudinal ligament;
determine, based at least in part on the simulation of implantation of the one or more cages, one or more dimensions of each of one or more patient-specific cages for the vertebral segment of interest, wherein the one or more dimensions of each of the one or more patient-specific cages comprises posterior height and anterior height thereof;
and
generate cage manufacturing or selection data instructions, based at least in part on the determined one or more dimensions of each of the one or more patient-specific cages, for use by a cage manufacturing or selection apparatus for producing or selecting the one or more patient-specific cages for the one or more intervertebral spaces,
wherein the patient-specific spinal rod for the vertebral segment of interest is produced or selected from a pre-existing range of spinal rods based at least in part on the generated spinal rod manufacturing or selection data instructions, and wherein the one or more patient-specific cages for the one or more intervertebral spaces are produced or selected from a pre-existing range of cages based at least in part on the generated cage manufacturing or selection data instructions.
