Lumbar Fusion

A fusion is a surgical technique in which one or more of the vertebrae of the spine are united together (“fused”) so that motion no longer occurs between them. During a fusion, bone grafts are placed around the spine. The body then heals the grafts over several months – similar to healing a fracture – which joins the vertebrae together.

The two least controversial reasons for a lumbar fusion are for cases that involve trauma or tumor. In both of these cases, either:

• The situation in the spine appears unstable, meaning the spine is prone to unusual movements under normal conditions which can damage tissues or cause pain or deformity, due to the underlying pathology.
• The surgery required to decompress the neural structures is deemed to render the spine unstable once this is achieved.

Fusion for degenerative disease (so-called “wear and tear”) is commonly performed. In this setting, a fusion can also be performed for many reasons. The most common reason to perform a fusion is for a spondylolisthesis. This is where one vertebra is slipped forward in relation to another. Not only does this throw the back out of alignment but it can cause pressure on nerves, particularly when they exit through their neural foramina.

A lumbar fusion requires the use of rods and screws. The rods are wedged between the screws in the vertebrae bone. The bone graft is then placed around these. The screws that are used during this operation are made of titanium, and usually, stay in for life.
