Lumbar spinal fusion is a surgical procedure that involves permanently connecting two or more vertebrae in the lower back (lumbar spine) to eliminate movement between them. This procedure is often performed to reduce pain and improve stability in the spine, especially in cases where the spine is unstable or deformed.

When Is Lumbar Spinal Fusion Recommended?

Lumbar spinal fusion may be recommended for several conditions, including:

Degenerative Disc Disease: Where the intervertebral discs deteriorate, causing pain and instability.

Spondylolisthesis: A condition where one vertebra slips forward over the one below it.

Spinal Stenosis: A narrowing of the spinal canal that puts pressure on the nerves.

Spinal deformity A curvature of the spine – scoliosis, kyphosis or both.

Fractures: Spinal fractures that cause instability.

How is Lumbar Spinal Fusion Performed?

Lumbar spinal fusion can be performed using several different techniques, each with its specific approach depending on the patient’s anatomy, comorbidities, the specific pathology treated, and the desired outcome.

Fusion requires stabilisation of the vertebrae involved using implants (eg screws, rods, cages), and placing bone graft on the prepared bone surfaces to form a column of bone between the desired vertebrae. The ultimate success of spinal fusion is the formation of the column of bone between these vertebrae.

These fusion techniques can be performed by approaching the spine from one or several directions including:

Anterior – from the front of the spine

Lateral – from the side of the spine

Posterior – from the back of the spine.

Each of these techniques has specific indications, benefits, and potential risks. The choice of technique depends on the patient’s anatomy, and the underlying condition being treated. A/Prof Buckland utilizes multiple different techniques to tailor the procedure to your specific problem. The specific recommendation will be discussed with you in detail.
