1. A computer-implemented method for designing a patient-specific lumbar implant based on modeled anatomical changes, the method comprising:
receiving patient data, the patient data including:
image data of a spinal region of a patient, including at least portions of a lumbar spine, a thoracic spine, and a cervical spine of the patient;
generating a virtual three-dimensional model of the spinal region based on the image data, the virtual three-dimensional model including the at least portions of the lumbar spine, the thoracic spine, and the cervical spine;
virtually simulating changes along a spine of the patient caused by implantation of a patient-specific lumbar implant by:
determining one or more lumbar anatomical changes to the lumbar spine to provide a corrective adjustment based on at least one patient-specific lumbar implant that is virtually implanted along the lumbar spine in the virtual three-dimensional model;
determining one or more anatomical changes to at least one of the thoracic spine or the cervical spine of the patient caused by the one or more lumbar anatomical changes to the lumbar spine;
determining the one or more anatomical changes to at least one of the thoracic spine or the cervical spine of the patient are acceptable; and
displaying the virtual three-dimensional model showing the one or more lumbar anatomical changes and the one or more anatomical changes to at least one of the thoracic spine or the cervical spine of the patient; and
designing the patient-specific lumbar implant configured to provide the corrective adjustment when implanted in the patient.
