Lumbosacral Fusion Surgery is a procedure that fuses vertebrae together in the lumbosacral region of the spine as a result of degeneration and diseases that affect that area of the spine such as a herniated or ruptured disc, vertebral compression fractures or degenerative spondylolisthesis. Lumbosacral fusion surgery is often performed in tandem with another surgery that deals with the underlying problem. For example, if a herniated disc in the lumbosacral area of the spine is the problem, the spine surgeon first removes the damaged disc. Then the surgeon inserts bone graft material to replace the herniated disc so that the two vertebrae fuse together. The fusion of the two vertebrae restores stability to the spine.
The Lumbosacral Spine
The lumbosacral area of the spine is the point where the last vertebra of the lumbar spine (lower back) connects to the first vertebra of the sacral spine (below the lumbar and part of the pelvic region).The five lumbar vertebrae experience a great deal of motion and flexibility and also have an important weight-bearing function. The sacral vertebrae consist of five bony segments that are fused together to form a triangle. The lumbosacral joint is very involved in the many movements related to this region of the spine, including walking, running, twisting, jumping, bending and lifting. That's why the lumbosacral spine is highly susceptible to debilitating problems and conditions. The lumbosacral segment, where the lumbar and sacral regions meet, is prone to degeneration and disease.
Diseases Treated with Lumbosacral Fusion Surgery
Lumbosacral spondylosis is the general term for a variety of degenerative spinal abnormalities that run the risk of protruding into the spinal canal and exerting pressure on spinal nerves where the last vertebra of the lumbar spine and the first vertebra of the sacral spine connect. When severe, these conditions can be repaired with lumbosacral fusion surgery:
