Minimally Invasive Spine Surgery (MISS)

Micro-Endoscopic Spine Surgery

‘Micro-Endoscopic Spinal Surgery’ is a revolutionary technique in which the routine spinal surgeries are performed using a ‘key-hole’. The procedures that can be performed with this cutting-edge technology are discectomies (for slipped disc), decompression (for lumbar canal stenosis) and spinal fusion (for spinal instability). Using this ‘micro-endoscopic’ technique, all objectives of the surgery can be achieved with minimal collateral damage to the soft tissues (muscles and ligaments) and bones. Clinical studies have proven that patients who undergo minimally invasive spine surgery benefit over those patients who received open spine surgery.

Tubular retractors with diameters of 16mm, 18mm and 22mm are passed through key holes to perform the procedure. The procedure leaves a miniscule scar (1.5 – 2cm long) and gives the appearance of a small scratch.

Some of these proven benefits are:

  • Better cosmetic results from ‘key hole’ incisions
  • Less blood loss from surgery
  • Reduced risk of muscle damage since muscle sparing techniques
  • Less postoperative pain
  • Faster recover from surgery and less rehabilitation required
  • Reduced dependence on pain medications after surgery

Patients requiring spine surgery are usually the elderly, with multiple co-morbidities (diabetes, hypertension, heart and lung issues) and this swift and painless procedure makes a big difference in earlier recovery. Dr Dutta’s scientific research work published in Asian Spine Journal reveals that only 1 in 1000 patients operated using this micro endoscopic technique may suffer from an infection as compared to 1 in 25 patients with open spine surgery. Obesity in spine patients is also common, as leg pain restricts activity. Open spine surgery in this subgroup of patients results in big incisions with prolonged recovery time. Key hole surgery is a perfect solution to this problem. Patients usually walk few hours after surgery and can go home the next day.

Apart from Micro-Endoscopic Decompressions/Discectomies, this technique can be used for Minimally invasive fusions (MIS-TLIF) also. Carefully selected patients of traumatic injury to the spine are also candidates for MIS-Fixation where-in the entire instrumentation can be done through stab incisions in the skin. Other MIS (Minimally Invasive Surgery) procedures include vertebroplasty (done under Local Anaesthesia) and vertebroplasty supplemented with MIS Fixation.

While not every patient is a candidate for minimally invasive spine surgery, Dr. Dutta will perform minimally invasive spine surgery on every patient who can benefit from a minimally invasive procedures while ensuring the safety and best possible outcome for that patient.
