The mortality rate of lumbar laminectomy procedures is estimated at 0.8 to 1 percent, according to Encyclopedia of Surgery medical experts. Roughly 6 to 7 percent of surgeries result in post-op complications; this increases to 12 percent among those involving spinal fusion.
The success rate of such procedures is estimated at 64 percent, cites Encyclopedia of Surgery. While studies indicate that as many as 31 percent of patients are dissatisfied with the results, medical professionals believe the high rate is due to unrealistic expectations. Since the average total cost of a laminectomy approaches $85,000, the surgery is often viewed as a last resort by patients suffering from lower back pain. The most common alternatives are minimally invasive laminotomy and microdiscectomy.
