A study published in the Journal of Spinal Disorders and Techniques examined the risk factors for radiographic L5-S1 disc height reduction after lumbar posterolateral floating fusion surgery.
The researchers examined 86 patients who underwent the procedure from 2007 to 2010 with a two- to six-year follow-up. The average patient age was 65.4 years old, and the patients were almost evenly split male and female.
Here are five findings from the study:
• 30.2 percent of the patients had disc height reduction
• Patients without disc height reduction had significantly more levels fused
• L1-S1 sacrolumbar alignment changed after patients without disc height reduction underwent surgery
