Robotic Spine Surgery at Bangkok International Hospital

Robotic spine surgery represents the latest evolution in precision spinal care — combining the expertise of a fellowship-trained spine surgeon with computer-guided robotic navigation to achieve sub-millimetre accuracy in implant placement. At Bangkok International Hospital, Dr. Chaidej Sasomboon utilises robotic navigation technology to deliver outcomes that exceed the precision limits of traditional freehand technique, all through minimally invasive approaches.

Bangkok International Hospital is among the leading centres in Southeast Asia for robotic-assisted spine surgery — providing international patients access to technology equivalent to the best spine centres in the USA and Europe, at a fraction of the cost.

What is Robotic Spine Surgery?

O-arm navigation-assisted spine surgery is a computer-assisted surgical system in which a pre-operative surgical plan is created from the patient’s CT scan data, and the O-arm navigation system guides the surgeon’s instruments along the planned trajectories with submillimetre accuracy. The surgeon remains in full control at all times — the navigation system does not operate independently; it amplifies the surgeon’s precision.

The system used at Bangkok International Hospital integrates:

• Intraoperative CT (O-arm): 3D cone-beam CT scanner that captures the patient’s exact anatomy on the operating table — accounting for differences from pre-operative imaging
• Navigation workstation: Real-time 3D imaging and trajectory planning during surgery
• Navigation display: Real-time 3D trajectory overlay shows the surgeon the exact instrument position and planned path — enabling submillimetre accuracy through image-guided navigation

Why Robotic Accuracy Matters in Spine Surgery

The single most important determinant of fusion surgery outcomes is accurate pedicle screw placement. Pedicle screws are the anchors that hold fusion constructs in place — misplaced screws can damage nerves, vessels, or fail to provide adequate fixation. Published accuracy data tells a clear story:

• Freehand technique: 5–15% screw malposition rate in published series
• Fluoroscopy-guided: 3–8% misplacement rate
• Robotic-assisted: Less than 1.5% clinically significant malposition rate in peer-reviewed literature

Higher screw accuracy directly translates to: fewer neurological complications from screw breaches, lower reoperation rates, more reliable fusion, and the ability to place screws safely through smaller incisions (percutaneous).

Conditions Treated with Robotic Spine Surgery

Spondylolisthesis (Slipped Vertebra)

Robotic MIS-TLIF and OLIF (Minimally Invasive Transforaminal Lumbar Interbody Fusion) is particularly valuable when treating spondylolisthesis — the altered anatomy and potential for intraoperative movement makes robotic accuracy especially advantageous. Percutaneous screws are placed through stab incisions of less than 1 cm each, guided entirely by the robotic system.

Degenerative Disc Disease with Spinal Instability

For patients requiring lumbar fusion for severe disc degeneration with instability, robotic-guided MIS-TLIF and OLIF provides reproducible, accurate fixation through minimal incisions.

Spinal Stenosis with Instability

When spinal stenosis co-exists with instability or spondylolisthesis, combined decompression and robotic-guided fusion in a single procedure is the optimal approach.

Complex or Revision Spine Surgery

Revision surgery — when a patient has had previous spine operations — presents significant challenges because normal anatomical landmarks are obscured by scar tissue and altered bone. Robotic navigation is particularly valuable in these cases, using the patient’s actual intraoperative 3D CT to plan around altered anatomy.

Multilevel Fusion

For patients requiring fusion of two or more levels, robotic systems dramatically reduce the risk of screw misplacement that multiplies with each additional level.

Deformity Correction

Adult spinal deformity (scoliosis, kyphosis) correction requires precise screw placement across multiple levels and sometimes complex anatomy. Robotic guidance reduces the risk and improves the reproducibility of deformity correction surgery.

Osteoporotic Spine

In patients with osteoporosis (low bone density), pedicles are more fragile and cortical bone breaches are more consequential. Robotic accuracy reduces the risk of screw pullout and cortical breach in osteoporotic bone.

The Robotic Surgery Procedure: Step by Step

1. Pre-operative CT scan: A dedicated CT scan of the relevant spinal segments is obtained (if not already available) — this provides the 3D dataset for surgical planning
2. Surgical planning: Dr. Chaidej plans screw sizes, trajectories, and entry points on the navigation workstation before entering the operating room — every screw position is determined in advance
3. Intraoperative registration: On the operating table, the O-arm captures a 3D CT that is registered to the patient’s anatomy — matching the pre-operative plan to the patient’s actual position
4. Navigation-guided instrumentation: The O-arm navigation workstation displays the real-time instrument position relative to the planned trajectory. The surgeon aligns the drill guide using live navigation feedback, makes a stab incision, and advances the instruments to the planned depth with submillimetre accuracy
5. Intraoperative confirmation: After screw placement, a repeat O-arm image confirms all screw positions in 3D before closure — no post-operative CT needed
6. Wound closure: Each screw entry site is closed with a single suture — a linear scar of less than 1 cm each

Robotic vs Standard Minimally Invasive Spine Surgery

Robotic surgery is a specific technique within the broader MISS framework — not all minimally invasive spine surgery uses robotics, and not all patients need robotic assistance:

• Standard MIS (endoscopic discectomy, laminectomy): Does not require robotic guidance — these procedures do not involve instrumentation placement
• Robotic MIS-TLIF and OLIF / fusion: Specifically benefits from robotic accuracy for pedicle screw placement
• Single-level, straightforward anatomy: Experienced surgeons achieve excellent accuracy without robotics — Dr. Chaidej makes the technique selection based on complexity, not routine
• Complex cases, revision surgery, multilevel fusion: Robotic guidance provides the greatest marginal benefit

• Columbia University Och Spine Hospital (2020): Advanced fellowship at a centre known for complex spine and robotic-assisted procedures
• UCSF San Francisco (2019): Observership at one of the highest-volume academic spine centres globally
• Ongoing education: Active NASS (North American Spine Society) member — attends annual congresses presenting the latest robotic spine surgery evidence and technique updates

At Bangkok International Hospital, Dr. Chaidej works within a multidisciplinary spine team with access to the full range of intraoperative technology — O-arm, robotic navigation, intraoperative neurophysiological monitoring (IONM), and high-definition endoscopy — allowing him to apply the optimal technology for each individual patient.

Recovery After Robotic Spine Surgery

Because robotic spine surgery at Bangkok International Hospital is performed through minimally invasive approaches, recovery is consistent with MIS outcomes:

• Day 0–1: Mobilisation with physiotherapist on the day of or day after surgery
• Day 2–3: Hospital discharge (for single-level robotic MIS-TLIF and OLIF)
• Week 2: Return to light daily activities; walking programme
• Week 4–6: Return to desk work
• Month 3: Early fusion confirmed on CT; progressive activity restoration
• Month 6–12: Full activity recovery for the majority of patients

International patients typically plan for 14–21 days in Bangkok for robotic fusion procedures, with telemedicine follow-up after returning home.

Frequently Asked Questions about Robotic Spine Surgery

Is robotic spine surgery available in Bangkok?

Yes — Bangkok International Hospital is equipped with robotic navigation technology for spine surgery, and Dr. Chaidej Sasomboon is trained and experienced in its application. Bangkok is a leading medical tourism destination for spine surgery precisely because JCI-accredited hospitals like Bangkok International Hospital invest in the same technology as top Western centres.

Does the robot do the surgery, or does the surgeon?

The surgeon performs the surgery — the robot provides guidance and accuracy assistance. Think of it as GPS navigation for the spine: the surgeon drives, the robot gives precise directions. Dr. Chaidej controls every incision, instrument, and decision throughout the procedure. The robotic system ensures his instruments follow the pre-planned trajectory with mechanical precision beyond freehand capability.

Is robotic spine surgery more expensive?

Robotic spine surgery has higher equipment costs, which is reflected in the procedure cost. However, the cost of robotic MIS-TLIF and OLIF at Bangkok International Hospital is still dramatically less than equivalent procedures in the USA, UK, or Australia. The reduced risk of complications and reoperation also represents long-term cost savings. Contact BH******@*************AL.COM for a personalised estimate.
