Keyhole spine surgery, also known as minimally invasive spine surgery, is a modern technique that treats spinal conditions through small incisions. It uses specialised tools and real-time imaging to access the spine with minimal disruption to surrounding muscles and tissues.
This procedure is commonly used for herniated discs, spinal stenosis, or nerve compression. Patients typically experience less pain, reduced blood loss, shorter hospital stays, and faster recovery compared to traditional open surgery.
Keyhole spine surgery is performed under general anaesthesia and often requires only a few stitches. It offers a safer alternative with excellent long-term outcomes when performed by experienced spine surgeons.
- Persistent or worsening back or neck pain
- Radiating pain into the arms or legs
- Numbness, tingling, or weakness in limbs
- Difficulty walking or balancing
- Loss of bladder or bowel control (a medical emergency)
- A detailed physical examination
- MRI, CT scans, or X-rays to localise the spinal issue
- Review of current medications, especially blood thinners, which may need to be paused
- Fasting for 6–8 hours before the procedure if general anaesthesia is used
- Discuss allergies, medical history, and potential surgical risks with your doctor
- Incision & Access: A small incision (usually less than 1 inch) is made. Surgeons use a tubular retractor to create a channel to the spine without cutting large muscles.
- Microscopic Tools: With the aid of a surgical microscope or endoscope, the surgeon visualises the spinal structures.
- Treatment: Damaged discs, bone spurs, or other problematic tissues are removed or repaired.
- Closure: Once completed, the incision is closed with minimal sutures or skin adhesive, and a small bandage is applied to the area.
- Bleeding
- Infection
- Nerve injury
- Spinal fluid leakage
- Blood clots
- Incomplete symptom relief
- Reaction to anaesthesia
- Smaller incisions and less muscle damage
- Shorter hospital stay (often outpatient)
- Reduced pain and faster recovery
- Lower infection risk
- Minimal blood loss
- Improved mobility and function
- High satisfaction rates among patients
- Patients are monitored for a few hours or overnight
- Mild discomfort or soreness around the incision site is common
- Most can walk the same day
- Return to light activities within 1–2 weeks
- Avoid heavy lifting and strenuous activity for 4–6 weeks
- Follow-up appointments and physical therapy may be recommended to optimise recovery

+99Process Involved for Keyhole Spine Surgery
Initial Evaluation and Diagnosis
- The doctor reviews your symptoms and performs physical exams and spinal imaging.
- Imaging tests, such as MRI or CT scans, provide detailed views to identify the specific area and cause of the spinal problem.
Detailed Consultation and Counselling
- The surgical process, risks, expected benefits, and outcomes are clearly explained.
- Patients are encouraged to ask questions and provide consent only after they have a complete understanding.
Preoperative Guidelines
- You may be asked to fast for 6–8 hours before the surgery to prepare for anaesthesia.
- Certain medications may need to be adjusted, especially blood thinners or diabetes medications.
Hospital Admission and Preparation
- Depending on the patient's condition and hospital protocol, admission may occur either on the day of surgery or one day prior.
- Basic tests are performed, and the surgical area is prepared and marked.
Anaesthesia and Positioning
- General anaesthesia is administered so you are unconscious and pain-free.
- The body is gently positioned to allow safe and accurate surgical access.
Minimally Invasive Surgical Technique
- A small incision is made near the affected spine segment.
- Special instruments and a microscope or endoscope are used to navigate safely.
Targeted Treatment of the Problem Area
- The damaged disc, compressed nerve, or bone fragment is removed or repaired.
- In some cases, spinal fusion or support devices may be placed to stabilise the spine.
Closing the Incision and Recovery Room Transfer
- The incision is closed using sutures or skin glue for faster healing.
- You’re moved to a recovery area where vital signs are continuously monitored.
Post-Surgery Observation and Pain Control
- Pain relief is provided through oral or IV medication as needed.
- Early movement is encouraged, and most patients start walking the same day.
Safe Discharge and Home Recovery Plan
- Patients are usually discharged within 24 to 48 hours if stable.
- Detailed instructions on activity limits, medications, and wound care are given.
Follow-Up and Rehabilitation Support
- Scheduled follow-ups help track healing progress and prevent complications.
- Physiotherapy may be recommended to restore strength and spinal mobility.
- Bulging or Slipped Disc: When spinal discs push out of place and irritate nearby nerves.
- Narrow Spinal Canal (Spinal Stenosis): Causes nerve compression and pain due to reduced space in the spine.
- Nerve Root Compression (Sciatica): Causes sharp or burning pain that radiates down the leg, typically due to irritation or pressure on the sciatic nerve.
- Worn-Out Discs (Degenerative Disc Disease): Discs lose cushioning over time, leading to discomfort and reduced movement.
- Vertebral Slippage (Spondylolisthesis): Occurs when one vertebra shifts forward over another, affecting spinal stability.
- Minor Spinal Fractures: Fractures from injury or weak bones that can be stabilised through minimally invasive techniques.
- Unstable Spine Segments: Unnatural motion between vertebrae that leads to chronic back pain or nerve issues.
- Nerve Entrapment: When surrounding tissues or discs press on a spinal nerve, causing pain or numbness.
- Select Non-Cancerous Tumours: Small, non-aggressive spine tumours may be removed using a keyhole approach.
- Initial Assessment: A thorough medical evaluation is conducted, including physical exams and imaging tests such as MRI or CT scans, to confirm the need for surgery.
- Pre-Surgical Preparation: The patient receives guidance on when to stop eating and drinking, how to manage current medications, and details about the hospital admission process. The type of anaesthesia and possible surgical risks are also clearly explained beforehand.
- Anaesthesia and Positioning: The patient is placed under general anaesthesia and carefully positioned—usually face down—for safe and accurate access to the spine.
- Creating a Small Incision: A tiny cut (usually under 2 cm) is made on the back. Muscles are gently moved aside using special instruments without cutting them.
- Using a Microscope or Endoscope: A camera or microscope is inserted to provide a clear, magnified view of the spine, helping the surgeon operate with great precision.
- Surgical Correction: The damaged part—like a slipped disc or bone spur—is removed or repaired using specialised tools inserted through the same small opening.
- Wound Closure: Once the procedure is complete, the small cut is sealed using either surgical glue or a single stitch, followed by the application of a light dressing to protect the area.
- Post-Surgery Monitoring: The patient is observed in a recovery room and discharged within 1–3 days. Follow-up care typically includes medication, exercise guidance, and, in some cases, physical therapy.
- Discectomy
- Laminectomy
- Foraminotomy
- Fusion
- Vertebroplasty
- Kyphoplasty
- Decompression
- Stabilisation
- Corpectomy (in select cases)
- Nucleoplasty
- Smaller Incision: Less cutting means reduced scarring and faster healing.
- Less Pain: Minimal tissue damage leads to lower pain levels after surgery.
- Faster Recovery: Most patients return to normal activities much sooner than with open surgery.
- Shorter Hospital Stay: Many can go home within 1–3 days.
- Lower Risk of Infection: Smaller wounds reduce the chance of postoperative infections.
- Preserves Muscle Strength: Muscles are gently moved aside, rather than cut, which helps maintain mobility.
- Less Blood Loss: The minimally invasive technique helps reduce bleeding during surgery.
- Better Precision: Surgeons use high-definition cameras or microscopes for improved accuracy.
