Excessive postoperative pain always occurs after Spinal Fusion due to soft tissue injury, muscle trauma and necrosis all caused by the surgeon. During TLIF and lateral Spinal Fusion the muscles are torn off the spine to get down to the disc. The dying back muscles cause severe postoperative inflammation and pain that always requires opioid painkillers and muscle relaxers. Opioid painkillers are highly addicting, cause tolerance, abuse and even death from breathing failure.
