AI transforms complex spinal procedures with faster planning and greater surgical precision
Tan Tock Seng Hospital is redefining complex spinal surgery through artificial intelligence, improving speed, precision, and patient recovery as Singapore’s ageing population faces rising spinal health challenges.
AI Steps Into the Operating Theatre
As more seniors develop spinal deformities such as degenerative scoliosis and nerve compression, hospitals across Singapore are rapidly adopting AI to support diagnostics and treatment planning. Tan Tock Seng Hospital’s orthopaedic surgery department has been a leader in this shift, performing more than 250 AI-assisted spinal operations since 2021. These procedures primarily involve elderly patients who often present with complex spinal conditions.
Transforming How Surgeons Plan and Operate
Traditionally, surgeons determined screw placements, rod angles, and spinal corrections only after the patient was on the operating table. This approach relied heavily on professional judgment and could lead to variable accuracy because the spine appears differently when a patient lies flat versus standing upright.
With AI, these critical decisions can now be made before entering the operating theatre. The system generates highly detailed pre-surgical plans, allowing surgeons to focus on nuanced decisions during the operation, such as adjusting implant angles for patients with osteoporosis.
Medtronic’s Predictive Modelling Enhances Precision
The AI tool, developed in Europe by medtech company Medtronic, automatically analyses X-rays and builds predictive models of surgical outcomes. It helps determine whether a patient’s spine can be straightened to a safe and functional state. Surgeons can also customise implant positions and design rods with precise bends tailored to each patient’s anatomy. According to Adjunct Associate Professor Jacob Oh, this eliminates guesswork and significantly improves the consistency of spinal corrections.
Shorter Surgery Time and Faster Recovery
AI-assisted procedures have reduced hospital stays by up to 50 percent, decreasing post-surgery recovery periods from seven to fourteen days to just three to six days. Surgery duration has also dropped by as much as 20 percent, since detailed planning is completed beforehand. The robotic navigation arm further enhances accuracy, reducing risks of nerve or organ damage that could lead to paralysis or death.
Zero Major Complications Reported
TTSH reports that none of its AI-assisted spinal surgery patients experienced paralysis, death, or the need for revision surgery. No patients required admission to intensive care following their procedure. This level of consistency underscores how the technology strengthens surgical safety and outcomes.
Higher Costs, But Strong Patient Acceptance
The advanced technology comes with a modest price increase. AI-assisted procedures result in an average 5 to 10 percent higher pre-subsidy bill, largely due to custom-made rods imported from France, which cost around 50 percent more than traditional rods priced at about $1,000. Despite the added cost, patient interest has not declined, reflecting strong confidence in the improved safety and recovery benefits.
The integration of AI into spinal surgery at Tan Tock Seng Hospital reflects a major advancement in Southeast Asian healthcare. As complex spinal conditions rise among older populations in both Singapore and Indonesia, innovations like AI-driven planning and robotic assistance set a new benchmark for safer, faster, and more predictable surgical outcomes in the region.
