Every year 10 million Americans have acute low back pain; only 286,000 (0.04%) require an operation, of which approximately one-fourth (70,000) are spinal fusions.1 In the United States, 2% of the adult population have had a previous lumbar spinal operation, and it is probable there are 500,000 to 1,000,000 living adults who have had a lumbar spinal fusion.2 These figures remind us spinal fusion is but a small part of the treatment for most low back disorders, and is usually indicated for the restoration of stability.
