Abstract
An interbody implant system for use in the spine includes a base comprising two or more bone contacting surfaces, at least one recess in at least one of the two or more bone contacting surfaces, the recess configured for containing a tooth, a deployable tooth to provide fixation between the base and the anatomy of a subject, a break-away bridge between the tooth and the base for providing a first relative position between the tooth and the base, and a locking mechanism for providing a second relative position between the tooth and the base.
Claims15
A computer-implemented method of designing a patient-specific implant system for a patient, the method comprising:
- generating an adjustable virtual three-dimensional model of at least a portion of the spine of the patient;
- receiving one or more user-inputted adjustments to the adjustable virtual three-dimensional model to provide one or more patient-specific corrections to the patient's spine;
- mapping, using the adjustable virtual three-dimensional model showing the one or more patient-specific corrections, a negative space between a first vertebral body endplate and a second vertebral body endplate, wherein the negative space includes contouring corresponding to patient-specific contouring of the first vertebral body endplate and the second vertebral body endplate;
- and
- designing a patient-specific implant system configured to provide the one or more patient-specific corrections when implanted in the patient, the patient-specific implant system including
- a base configured to be implanted between the first vertebral body endplate and the second vertebral body endplate and having a shape corresponding to the mapped negative space such that the base comprises a first bone contacting surface having a first patient-specific shape corresponding to the patient-specific contouring of the first vertebral body endplate and a second bone contacting surface having a second patient-specific shape corresponding to the patient-specific contouring of the second vertebral endplate;
- and
- a deployable fixation element configured to provide fixation between the base and at least one of the first or second vertebral body endplates.
A method of designing a patient-specific interbody implant system for a patient, the method comprising:
- non-invasively determining a patient-specific correction for the spine of the patient by adjusting a virtual three-dimensional model of at least a portion of the spine of the patient;
- and
- mapping, using the adjusted virtual three-dimensional model showing the patient-specific correction, a negative space between a first vertebral body endplate and a second vertebral body endplate the spine of the patient, wherein the negative space includes contouring corresponding to patient-specific contouring of the first vertebral body endplate and the second vertebral body endplate;
- and
- designing a patient-specific interbody implant system based at least in part on the adjusted virtual three-dimensional model and configured to provide the patient-specific correction when implanted in the spine of the patient, the patient-specific interbody implant system comprising:
- a base configured to be implanted between the first vertebral body endplate and the second vertebral body endplate and having a shape corresponding to the mapped negative space such that the base comprises a first bone contacting surface having a first patient-specific shape corresponding to the patient-specific contouring of the first vertebral body endplate and a second bone contacting surface having a second patient-specific shape corresponding to the patient-specific contouring of the second vertebral body endplate;
- and
- a deployable fixation element configured to provide fixation between the base and at least one of the first or second body vertebral endplates.
