Open spine surgery involves a single long incision over the spine with retraction of the paraspinal muscles away from the spine's bony structures. This approach provides excellent visibility but causes significant muscle trauma, blood loss, and postoperative pain, and typically requires a hospital stay of five to seven days with a recovery period of six to twelve weeks before return to normal activity. Minimally invasive spine surgery achieves the same surgical goals - decompression of nerves, stabilisation of the spine, removal of disc material - through one or more small incisions of approximately one to two centimetres, using specialised tubular retractors that separate rather than cut through the muscle, or through endoscopic instruments that access the spine through even smaller portals. The result is dramatically less tissue disruption, shorter hospital stay of one to two days, faster recovery of two to four weeks, and comparable or superior outcomes in appropriately selected cases. My spinal fellowship at Flinders Medical Centre, Adelaide, trained me specifically in minimally invasive techniques, and at Gleneagles Fortis Hospital, Chennai, I use these approaches for disc prolapse, decompression for spinal stenosis, and selected fusion procedures. You should ask your neurosurgeon directly which approach they are planning and why - understanding whether your procedure is minimally invasive or open, and what the rationale is for that choice given your specific anatomy and pathology, is a reasonable and important question.
