Spine cage
A spine cage ( 1 ) comprising a pair of opposite functional sides ( 2,3 ) and at least another pair of opposite functional sides ( 4,5 ), such that the cage can be positioned in at least two different positions providing at least two different configurations.
1. A method of inserting a spine cage between two or more vertebrae for spinal fusion, the method comprising the steps of:
providing a spine cage including a first pair of opposite functional sides having a first bone fixation structure, and a second pair of opposite functional sides having a second bone fixation structure, a cross-sectional shape of the spine cage being rectangular, both the first and second bone fixation structures configured to engage directly with the two or more vertebra for fusion;
determining whether the spine cage fits into an intervertebral space of a given patient in a first position for fusion with the two or more vertebrae or in a second position for fusion with the two or more vertebrae that is a 90° rotation of the spine cage with respect to the first position;
inserting the spine cage into the intervertebral space either in the first position or in the second position based on the determining; and
fusioning the spine cage in either the first position or in the second position based on the inserting.
2. The method of claim 1 , further comprising the step of: fusioning the spine cage to the intervertebral space by transforaminal lumbar interbody fusion (TLIF), lateral lumbar interbody fusion (XLIF) and anterior Lumbar Interbody Fusion (ALIF).
3. The method of claim 1 , further comprising the step of:
inserting a second spine cage into the intervertebral space in posterior lumbar interbody fusion (PLIF).
