Treating Spondylolisthesis Through Keyhole Surgery

For office workers: correct sitting posture throughout, back support maintained, screen at eye level, the angle between thigh and lower leg kept greater than 90 degrees, with regular breaks. I recommend pelvic tilts, leg raises, the Cobra pose and the Superman pose for everyone in this group. For heavy weightlifters with back pain but a largely normal MRI, return to lifting within six to eight weeks is reasonable; but with a prolapsed disc, the annulus tear needs six to nine months, sometimes up to a year, to heal, and early heavy loading risks the prolapse escalating into a full extrusion requiring surgery. For patients beyond 60, protein supplementation and resistance training to maintain paraspinal muscle mass become particularly important, since postural slouching and spinal deterioration are largely consequences of muscular atrophy.

Multi-level thoracic stenosis and multi-level lumbar disc disease can both be managed with MISS, including fixation at two or three levels, and technology now makes MISS technically feasible at four or even five levels — though each patient has to be assessed individually. As a broad guide: one- or two-level lumbar disease, MISS without question; three to four levels, roughly half our patients proceed with MISS and half need open surgery, mainly for anatomical reasons, not because MISS is inferior. For sequencing combined cervical and lumbar disease: if there's cervical cord compression causing weakness, we operate on the cervical spine first; if the cervical issue is just radiating arm pain without cord compression, we address the lumbar spine first.

A Cobb angle under 10 degrees isn't classified as scoliosis at all. Between 10 and 30 degrees, observation with serial X-rays is appropriate — the curve is largely safe at this stage. The tipping point for a surgical discussion is a Cobb angle approaching 40 degrees; below that, there's generally no urgent surgical indication. Beyond the angle itself, the second key factor is whether the curve stays within the coronal zone of stability — as long as it does, it's relatively safe, but once vertebral segments shift outside that zone, the curve is at high risk of rapid progression and surgery becomes necessary.

The biggest source of confidence for a patient is seeing or hearing from patients who have undergone the procedure — testimonials describing next-day mobilisation are very powerful, and the Artemis Hospitals website carries many of them. Beyond that, as technology spreads to more centres and results accumulate, outcomes will speak for themselves. The current primary limitation is availability of technology, not the evidence.

Safety and success are entirely separate concepts. When we say 99% safe, we mean that out of 100 patients, 99 will not deteriorate — they will not be made worse by the surgery. Success is different: a patient who arrives already paralysed, no technology anywhere in the world can guarantee that patient will walk. Success depends on the patient's pre-operative condition, the stage of disease on MRI, and their own functional expectations — which is why a one-to-one consultation is essential before anyone is given realistic clarity on likely outcomes.

A condition where one vertebra slips forward over the one below it.

Yes. Fracture reduction, cage placement, screw insertion, rod placement and full spinal realignment are all now achievable through small incisions under navigation, something once considered unthinkable to attempt through keyhole surgery.

The correction achieved is equivalent to open surgery, but with far less morbidity.

Navigation now enables precise, minimal-hardware constructs, where earlier practice would have required six, eight or even ten screws to achieve the same stability.
