Posterior Instrumented Fusion is an approved and effective method for fusing the lumbar spine. The goal of surgery is to decrease pain, correct spinal deformity, and improve stability. Complications may occur but are not common. The majority of patients are satisfied with their pain relief and the results of their surgery. It is important that all patients are physically and psychologically prepared. All patients should stop smoking prior to any surgery, as smoking is extremely detrimental to your spine health, potential bone healing and successful surgical outcomes. Please review additional details with your surgeon prior to your surgery.
