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.
Claims17
A patient-specific interbody implant system for use in a patient's spine, comprising:
- a base comprising two or more bone contacting surfaces including a first bone contacting surface having a first patient-specific shape configured to match a first vertebral endplate and a second bone contacting surface having a second patient-specific shape configured to match a second vertebral endplate of the patient, wherein the first patient-specific shape and the second patient-specific shape are non-invasively determined from a user-adjustable virtual three-dimensional model of at least the first vertebral endplate and the second vertebral endplate, the first patient-specific shape and the second patient-specific shape based on a version of the user-adjustable virtual three-dimensional model that incorporates one or more virtual user manipulations of the user-adjustable virtual three-dimensional model;
- at least one recess in at least one of the first or second bone contacting surfaces, the recess configured for containing a tooth;
- a deployable tooth configured to provide fixation between the base and at least one of the first or second vertebral endplates;
- 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,
- wherein the patient-specific interbody system is configured to provide a patient-specific correction to the patient's spine corresponding to the version of the user-adjustable virtual three-dimensional model that incorporates the one or more virtual user manipulations when the patient-specific interbody system is implanted between the first vertebral endplate and the second vertebral endplate.
A method for implanting a patient-specific implant within a spine of a patient, 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;
- providing a patient-specific interbody implant based at least in part of 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 implant comprising:
- a base comprising two or more bone contacting surfaces including a first bone contacting surface having a first patient-specific shape configured to match a first vertebral endplate and a second bone contacting surface having a second patient-specific shape configured to match a second vertebral endplate of the patient;
- at least one recess in at least one of the first or second bone contacting surfaces, the recess configured for containing a tooth;
- a deployable tooth configured to provide fixation between the base and at least one of the first or second vertebral endplates;
- 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;
- inserting the patient-specific interbody implant between the first and second vertebral endplates of the patient with the tooth and the base in the first relative position;
- and
- moving the tooth and the base into the second relative position.
