Similarly, in TTSH, its department of orthopaedic surgery has successfully performed more than 250 AI-assisted spinal surgical operations since 2021. These were mostly complex surgical operations for elderly patients.<\/p>\n
Complex spinal surgery used to be done with surgeons deciding on surgical details only in the operating theatre, such as the exact positions in the spine and the ideal angles to implant the screws and rods, as well as the contour of the rods.<\/p>\n
Rods and screws are implanted to hold the spine at its corrected position and keep the spine aligned properly. <\/p>\n
This process relied heavily on the surgeon\u2019s experience and could result in variable accuracy rates, given that the patient would be lying flat and presenting the spine differently compared with when standing straight, said Dr Wayne Yap, a consultant at TTSH\u2019s orthopaedic surgery department.<\/p>\n
With AI aiding pre-surgery planning and providing greater accuracy in the implantation of the screws and rods, TTSH surgeons can now concentrate on aspects of the surgery that require their professional expertise and skills.<\/p>\n
An example is a surgeon adjusting the angle of implantation for patients with osteoporosis, as their spinal bones would have softened, said Dr Yap.<\/p>\n
The AI tool developed in Europe by medtech company Medtronic allows for auto-analysis of the patient\u2019s X-ray to assess the state of the spine, as well as predictive modelling of the potential outcomes of the surgery, including if the spine can be straightened to a normal and functioning state. <\/p>\n
This pre-surgical planning can now be completed outside the operating theatre.<\/p>\n
In addition, \u201cthere is no more guesswork\u201d with the AI tool, which allows for visualisation and simulation. This allows surgeons to determine the optimal positions for implants and customise the size and bends of each rod used to correct the spine, said Adjunct Associate Professor Jacob Oh, head of spine surgery and a senior consultant at TTSH\u2019s orthopaedic surgery department.<\/p>\n
With the deployment of this AI tool, patients who underwent complex surgery saw a reduction of their hospitalisation by up to 50 per cent, from an average of about seven to 14 days post-surgery, to about three to six days, said Dr Yap.<\/p>\n
The surgery time saw a decrease of up to 20 per cent, as the planning work could be completed ahead of the surgery.<\/p>\n
The use of the AI-assisted robotic arm helped to navigate and ensure the precise insertion of the implants. This also reduced the surgical time needed and the likelihood of major complications due to damage to other nerves or organs near the surgery site, which could potentially lead to paralysis or even death.<\/p>\n
Of all TTSH patients who had AI-assisted spinal surgery, none died or was paralysed.<\/p>\n
Prof Oh said none of the patients had to undergo revision surgery to tighten any loose or misaligned screws, or had to be admitted to the intensive care unit after surgery.<\/p>\n
The use of advanced technologies comes at a price, for now.<\/p>\n
Patients who benefited from AI-assisted robotic spinal surgery at TTSH received, on average, a 5 per cent to 10 per cent higher pre-subsidy bill, mainly due to the costlier custom-made rods to be implanted.<\/p>\n
The rods used in traditional spinal surgery would have cost around $1,000 each, but the custom-made rods flown in from France cost 50 per cent more.<\/p>\n
Nevertheless, the slightly higher price tag for such AI-assisted surgery did not turn patients away.<\/p>\n
Madam Jenny Ee, 74, used to be an avid jogger and visited the gym five times a week.<\/p>\n
When she first experienced pain several years ago, which went from her lower back down to her left calf, she depended on oral painkillers.<\/p>\n
Soon, the painkillers did not have much effect, and spinal injections of steroids could give her only one to two pain-free days.<\/p>\n
It came to a point when she could barely walk for 10 minutes without resting. When she suddenly experienced excruciating pain while she was on the gym\u2019s treadmill, she finally considered surgery.<\/p>\n
She underwent open spinal surgery in July 2024 that lasted eight hours and was performed by Prof Oh. Twenty screws were implanted into her spine to fix the scoliosis.<\/p>\n
Post-surgery, she spent two days in a high dependency ward and five days in a general ward before transferring to the TTSH Integrated Care Hub for three weeks to complete her inpatient physiotherapy.<\/p>\n
Madam Ee can now brisk-walk a few kilometres each day, and has travelled to Taiwan and Malaysia.<\/p>\n
\u201cFrom the debilitating pain, which resulted in me not having a good quality of life and a complete standstill for all my normal activities, it was a huge relief that just one day after the surgery, I no longer feel the same pain down the nerve,\u201d she said.<\/p>\n
Before her surgery, she received an estimate of $70,000 to $80,000 for her total bill, with the consumables \u2013 the screws and rods \u2013 costing more than $30,000. <\/p>\n
She paid about $10,000 after receiving government subsidies, tapping coverage under MediShield Life and using her MediSave savings.<\/p>\n
\u201cAs I wanted my life back, this was worth it,\u201d said Madam Ee.<\/p>\n<\/div>\n
