Spinal fusion surgery is a procedure used to join two or more bones (vertebrae) in the spine so that they heal into one solid bone. This helps reduce pain, improve stability and prevent abnormal movement in the spine.

Overview

What is spinal fusion surgery?

Spinal fusion surgery is a procedure used to join two or more bones (vertebrae) in the spine so that they heal into one solid bone. This helps reduce pain, improve stability and prevent abnormal movement in the spine.

Common conditions leading to the surgery

• Degenerative disc disease (wear and tear of spinal discs)
• Slipped disc with spinal instability
• Spinal deformities such as scoliosis
• Spinal fractures or injuries
• Narrowing of the spinal canal (spinal stenosis)
• Spondylolisthesis (one spinal bone slipping over another)

When is surgery required?

Surgery may be considered when:

• Long-lasting back or neck pain does not improve with medicines, physiotherapy or lifestyle changes
• Pain spreads to the arms or legs, or causes numbness, tingling or muscle weakness
• Difficulty walking, standing or performing daily activities develops
• The spine becomes unstable due to ageing, arthritis, injury or repeated strain
• Severe symptoms such as loss of balance or trouble controlling urine or bowel movements occur
• Imaging tests such as X-rays, MRI or CT scans show significant spinal damage or nerve pressure

Procedure Details

What is the procedure and why is it done?

During spinal fusion surgery, the surgeon joins spinal bones using bone grafts, screws or rods. This limits painful movement and improves spine stability.

Before the Procedure

Key instructions

• Stop smoking if possible
• Inform the doctor about all medicines
• Arrange help at home after surgery

Preparation guidelines

• Avoid food or drinks for several hours before surgery
• Some blood-thinning medicines may need to be stopped temporarily
• Follow instructions about bathing and hospital admission

Procedure Overview

Step-by-step (simplified)

• Anaesthesia (general anaesthesia) is given so the patient sleeps during surgery
• A small cut is made in the back, neck or abdomen
• The damaged disc or tissue may be removed
• Bone graft material is placed between the spinal bones
• Screws or rods may be used to hold the spine in place while healing occurs

The procedure usually takes about 2–6 hours depending on the complexity.

Risks and Complications

Benefits and Expected Outcomes

Success rates

Many patients experience reduced pain and improved movement after recovery.

How the procedure improves quality of life

• Better ability to walk and perform daily activities
• Reduced nerve pain
• Improved spine stability

During hospital stay

Patients can expect:

• Monitoring in the recovery room
• Pain management medicines
• Early walking with assistance
• Physiotherapy guidance

Recovery, Lifestyle and Follow-up

Recovery and aftercare

Length of hospital stay

• Usually 2–5 days

Recovery timeline

• Light activities begins within a few weeks
• Full recovery may take several months

Activity restrictions

• Avoid heavy lifting and bending
• Follow exercise instructions carefully

Wound care and precautions

• Keep the wound clean and dry
• Watch for redness, swelling or discharge

Lifestyle and Prevention

Recommended diet

Long-term care

Preventing recurrence

When to Contact a Doctor

Seek medical help if there is:

• Fever or wound discharge
• Severe pain not improving
• New weakness or numbness
• Difficulty breathing
• Urine leakage or loss of bowel control

Follow-up schedule

Regular follow-up visits and imaging tests may be needed to check healing.
