| Type of Cage | Expandable cage, OptiMesh, modified TLIF cages | Open or MIS-TLIF cage |
| Handling of Facet | Preserved or foraminoplasty | Complete facetectomy |
| Availability of Autograft | Not from lumbar segment; obtained from iliac crest or other sources | Obtained from bony decompression and facet |
| Neural Decompression | Indirect decompression | Direct decompression |
| Method of Anesthesia | Local anesthesia, epidural, general anesthesia | Epidural, general anesthesia |
