Interbody cages aim to improve the stability and balance of the treated spinal segment, while also relieving pain and restoring function. The goals of spinal cages include .
- Restoring the height provided by the original intervertebral disc .
- Supporting the front (anterior) part of the spinal column .
- Expanding the bony openings between the vertebrae (foramina), providing more space for spinal nerves .
- Restoring the normal lordotic (S-shaped) curve of the lower (lumbar) spine
- Transferring loads from the upper segments to lower sections of the spine
- Promoting a solid fusing of the adjacent vertebral segments by promoting bone growth
- Increasing the spaces within the spinal canal to decrease the compression of neural tissue that may be indirectly compressed
