Abstract
A personalized fixation system includes a surgical planning software tool configured to adjust relationships of relevant anatomy of a subject, at least one bone anchor, a plate having a shape that does not conform to a single plane, the plate configured to accept the at least one bone anchor, wherein the shape of the plate is at least partially determined by the surgical planning software tool, and wherein the plate includes at least one node having a hole configured to receive the at least one bone anchor, and a locking element configured to connect the at least one bone anchor to the plate, wherein the plate is manufactured using additive manufacturing.
Claims30
A computer-implemented method for designing a patient-specific implant, comprising:
- causing display of a model of at least a portion of a patient's spinal anatomy in a virtual space;
- updating the model to display a corrected spinal anatomy in the virtual space, wherein the corrected spinal anatomy includes one or more changes to the patient's spinal anatomy, and wherein the one or more changes include a change to a spatial relationship between at least two vertebrae;
- determining one or more predicted post-operative spinal metrics associated with the corrected spinal anatomy, the one or more predicted post-operative spinal metrics including one or more of pelvic tilt, sagittal alignment, or lumbar lordosis;
- designing the patient-specific implant based at least in part on the corrected spinal anatomy such that, when implanted in the patient, the patient-specific implant directs the patient's spinal anatomy to or toward the corrected spinal anatomy;
- and
- causing fabrication of the patient-specific implant.
A non-transitory computer-readable medium storing instructions that, when executed by a computing system, cause the computing system to perform operations comprising:
- causing display of a model of at least a portion of a patient's spinal anatomy in a virtual space;
- updating the model to display a corrected spinal anatomy in the virtual space, wherein the corrected spinal anatomy includes one or more changes to the patient's spinal anatomy, and wherein the one or more changes include a change to a spatial relationship between at least two vertebrae;
- determining one or more predicted post-operative spinal metrics associated with the corrected spinal anatomy, the one or more predicted post-operative spinal metrics including one or more of pelvic tilt, sagittal alignment, or lumbar lordosis;
- designing a patient-specific implant based at least in part on the corrected spinal anatomy such that, when implanted in the patient, the patient-specific implant directs the patient's spinal anatomy to or toward the corrected spinal anatomy;
- and
- causing fabrication of the patient-specific implant.
A system for manufacturing a patient-specific implant, comprising:
- one or more processors;
- and
- one or more memories storing machine-readable instructions that, when executed by the one or more processors, cause the system to perform operations comprising:
- causing display of a model of at least a portion of a patient's spinal anatomy in a virtual space;
- updating the model to display a corrected spinal anatomy in the virtual space, wherein the corrected spinal anatomy includes one or more changes to the patient's spinal anatomy, and wherein the one or more changes include a change to a spatial relationship between at least two vertebrae;
- determining one or more predicted post-operative spinal metrics associated with the corrected spinal anatomy, the one or more predicted post-operative spinal metrics including one or more of pelvic tilt, sagittal alignment, or lumbar lordosis;
- designing the patient-specific implant based at least in part on the corrected spinal anatomy such that, when implanted in the patient, the patient-specific implant directs the patient's spinal anatomy to or toward the corrected spinal anatomy;
- and
- causing fabrication of the patient-specific implant.
