Abstract
An interbody spinal cage comprising: a body portion comprising a superior side, an inferior side and at least one lateral side connecting the superior side and the inferior side; and at least one endplate portion coupled to the superior side or the inferior side of the body portion, the at least one endplate portion comprising a unibody structure and operable to be fixedly coupled to an anatomical structure of a patient and decoupled from the superior side or the inferior side of the body portion.
Claims20
An interbody spinal cage comprising:
- a body portion comprising a superior side, an inferior side and at least one lateral side connecting the superior side and the inferior side, wherein the superior side, the inferior side, or both, are operable to be fixedly coupled to or within the spinal column of a patient;
- and
- a plurality of slits extending at least partially through the at least one lateral side, wherein the plurality of slits facilitates decoupling of the superior side, the inferior side, or both, from the body portion, wherein a subset of the plurality of slits have a recessed region that leads into the plurality of slits.
An interbody spinal cage comprising:
- a body portion comprising a superior side, an inferior side, and at least one lateral side connecting the superior side and the inferior side, wherein the superior side, the inferior side, or both, are operable to be fixedly coupled to or within the spinal column of a patient;
- a plurality of columns extending along the at least one lateral side towards the superior side, the inferior side, or both, wherein the plurality of columns is spaced apart to facilitate decoupling of the superior side, the inferior side, or both, from the body portion;
- and
- a slit disposed between the plurality of columns and extending along a direction substantially parallel to the superior side, the inferior side, or both, wherein a first length of the slit along the direction is longer than a second length of the plurality of columns extending along the direction.
An interbody spinal cage comprising:
- a body portion comprising a superior side, an inferior side and at least one lateral side connecting the superior side and the inferior side;
- and
- at least one endplate portion coupled to the superior side or the inferior side of the body portion, the at least one endplate portion comprising a structure and operable to be fixedly coupled to or within the spinal column of a patient and, wherein the interbody spinal cage comprises a plurality of slits extending at least partially through the at least one lateral side, wherein the plurality of slits facilitate decoupling of the at least one endplate portion from the superior side or the inferior side of the body portion, wherein a subset of the plurality of slits have a recessed region that leads into the plurality of slits.
