Minimally Invasive Spine Surgery

Minimally invasive spine surgery is a less disruptive alternative to traditional open surgery for selected spinal conditions. Rather than a single large incision, the procedure is performed through keyhole-sized openings (typically 1–3 cm) using specialised instruments, tubular retractors and imaging guidance to access and treat the spine while preserving the surrounding muscles, ligaments and healthy tissue as much as possible.

How does minimally invasive spine surgery work?

Minimally invasive spine surgery is performed using specialised miniature instruments and real-time imaging technology, such as fluoroscopy or navigation systems, to guide the surgeon accurately to the affected area of the spine. The procedure typically involves:

• Small, targeted skin incisions – One or more small incisions are made over the affected spinal level to allow access while limiting unnecessary tissue exposure.
• Gentle muscle separation instead of cutting – Rather than cutting through muscle layers extensively, specialised tubular retractors are used to gently separate muscle fibres and create a narrow working channel to the spine.
• Real-time imaging guidance – Imaging systems help guide the placement of surgical instruments and improve precision during the procedure while reducing the risk of injury to nearby structures.
• Targeted treatment of the spinal condition – Fine surgical instruments are used to address the underlying problem, such as removing part of a herniated disc, relieving pressure on compressed nerves or stabilising selected spinal segments.
• Smaller closure and reduced tissue trauma – After the procedure, the instruments are removed and the small incisions are closed. Because surrounding muscles and tissues are preserved as much as possible, patients may experience reduced blood loss, less post-operative discomfort and faster recovery in suitable cases.
  

What conditions can be treated with minimally invasive spine surgery?

Minimally invasive techniques may be suitable for a range of spinal conditions, including:

• Herniated or slipped discs – relieving nerve compression that causes back pain, leg pain or sciatica
• Spinal stenosis – widening the narrowed spinal canals to reduce nerve pressure
• Degenerative disc disease – addressing pain from worn or damaged discs
• Spondylolisthesis – stabilising vertebrae that have shifted out of position
• Spinal instability – selected cases requiring fusion with minimal tissue disruption
• Certain spinal fractures or deformities – depending on severity and anatomy

However, not all spine conditions are suitable for minimally invasive surgery. That is why careful assessment is required, as it helps to determine the safest and most effective approach.

What are the benefits of minimally invasive spine surgery?

Some of the benefits are:

• Smaller incisions and reduced scarring
• Less muscle damage and blood loss
• Lower risk of infection in suitable cases
• Reduced postoperative pain
• Shorter hospital stay
• Faster return to daily activities and work

Who is a suitable candidate to undergo minimally invasive spine surgery?

The procedure is not appropriate for every patient. Suitability depends on the specific diagnosis, spinal anatomy and overall health.

You may be a suitable candidate if you:

• Have persistent back or neck pain despite conservative treatment
• Experience nerve-related symptoms such as numbness, weakness or radiating pain
• Have imaging findings that correlate with your symptoms
• Are medically fit for surgery and able to participate in rehabilitation

Meanwhile, patients with complex spinal deformities, severe instability or widespread disease may require alternative surgical approaches.

How are spine conditions assessed before surgery?

A thorough and structured assessment is essential to determine whether surgery is necessary and whether a minimally invasive approach is appropriate. Dr James Tan will perform the assessment, which typically consists of:

• Detailed medical history and symptom review – our doctor begins by understanding the nature of your pain, its duration, severity and triggers. Particular attention is given to nerve-related symptoms such as radiating pain, numbness, tingling or weakness, as well as how symptoms affect daily activities, work and sleep.
• Comprehensive physical and neurological examination – the spine is examined for posture, alignment and range of motion. Neurological testing assesses muscle strength, reflexes and sensation to identify nerve involvement and correlate findings with reported symptoms.
• Personalised imaging studies – these give your doctor a comprehensive understanding of your condition, spine anatomy and overall well-being.
  • X-rays – these are used to assess spinal alignment, stability and degenerative changes.
  • Magnetic resonance imaging (MRI) scans – provide detailed images of discs, nerves and soft tissues, helping to identify disc herniation, stenosis or nerve compression.
  • Computed tomography (CT) scans – these may be used when detailed bone anatomy is required, particularly in cases involving fractures or previous surgery.

Correlation of findings for accurate diagnosis

Surgery is only considered when clinical symptoms, physical findings and imaging results clearly align. This ensures that treatment addresses the true source of pain and avoids unnecessary intervention.

What to expect during minimally invasive spine surgery

While the spine is a complex structure, minimally invasive surgery is designed to address problems in a focused and streamlined way.

Before the procedure
Pre-operative assessments confirm your fitness for surgery. The procedure, expected outcomes and recovery plan are discussed in detail, so you can make a fully informed decision.

During surgery
The operation is performed under general anaesthesia in a hospital setting. Depending on the procedure and spinal level being treated, one or more small incisions are made, typically measuring around 1–3 cm in length. Using specialised miniature instruments, tubular retractors and real-time imaging guidance, the surgeon accesses the affected spinal area through these small openings.

The underlying cause of symptoms, such as a herniated disc or nerve compression, is then treated with precision while minimising disruption to surrounding muscles and tissues.

Immediately after surgery
You will be closely monitored in the recovery area. Pain is carefully managed, and many patients are encouraged to sit up or walk on the same day, depending on the procedure.

Hospital stay and discharge
Some procedures allow same-day discharge; others require a short hospital stay. Clear guidance on wound care, activity levels and follow-up appointments is provided before discharge.

Recovery and rehabilitation after surgery

Recovery varies depending on the procedure performed and individual factors, but minimally invasive techniques often allow earlier mobilisation. Postoperative care may include:

• Short hospital stay or same-day discharge in selected cases
• Gradual return to walking and daily activities
• Pain management tailored to individual needs
• Structured physiotherapy to restore strength, flexibility and spinal stability
• Activity guidance to protect the spine during healing

Adhering to rehabilitation recommendations plays a key role in achieving optimal outcomes.
