Lumbar Spinal Fusion
What is Lumbar Spinal Fusion?
Lumbar spinal fusion is a surgical procedure designed to stabilise the spine by permanently joining two or more vertebrae. This is achieved by placing screws and/or a cage at the affected level to prevent abnormal movement that may cause pain or instability.
A bone graft, often taken from the patient and supplemented with a synthetic graft, is used to promote the fusion between the vertebrae. Over time, the bones grow together to create a solid, stable structure.
Who Can Benefit from Lumbar Spinal Fusion?
Lumbar spinal fusion may be recommended for patients experiencing:
- Spondylolisthesis – A condition where one vertebra slips forward over another, causing instability and pain.
- Spinal instability – Abnormal movement between vertebrae leading to chronic pain.
- Degenerative disc disease – Severe disc degeneration causing ongoing discomfort.
- Recurrent disc herniation – Where repeated disc prolapse requires stabilisation.
- Spinal fractures – In cases where the spine needs reinforcement for structural support.
What to Expect During the Procedure
Before Surgery
- A full assessment, including MRI and CT scans, will confirm the need for fusion.
- You will receive pre-operative instructions, including fasting guidelines.
- Mr. Rolton will discuss the best surgical technique for your condition.
During Surgery
- The procedure is performed under general anaesthesia.
- An incision is made over the affected area of the spine.
- Screws and/or a cage are placed at the unstable vertebral level.
- A bone graft is used to stimulate fusion between the vertebrae.
- The incision is carefully closed, minimising tissue disruption.
- The surgery typically takes 2–4 hours, depending on complexity.
After Surgery
- You will be monitored in a recovery area before being transferred to a hospital room.
- Pain relief medication will be provided.
- Patients typically stay in the hospital for 1–3 days before going home.

Recovery & Aftercare
Pain Relief
Some discomfort is expected initially, but pain typically improves as healing progresses. Medication will be provided to manage post-operative pain.
Activity Restrictions
-
Light activities may be resumed in the first few weeks.
-
Activities involving bending, twisting and lifting will be limited for the first 3 months
Physiotherapy
A rehabilitation program will be introduced to improve strength, flexibility, and spinal stability over time.
Follow-Up
-
Regular follow-ups will be scheduled to monitor fusion progress.
-
X-rays or scans may be required to assess bone healing.
How Long Does Recovery Take?
Initial recovery takes around 6–12 weeks, with full fusion and strengthening occurring over 6–12 months. Most patients return to normal activities gradually, based on healing progress and physiotherapy.
