Any sort of surgery can prompt feelings of unease and disquiet — particularly when it comes to the spine. Spinal fusions in particular may make some patients feel concerned. Permanently connecting two or more vertebrae sounds like a drastic step. However, much of that anxiety abates when they learn about the overall outcomes of spinal fusion. For example, F1000 Research pointed out how back surgery in general provides a reduction in pain and an increase in function. Another study published in the journal Neurosurgery also noted that different types of fusions significantly improved patients’ quality of life.
