Researchers identified 171 patients who underwent lumbar fusion to revise a previous lumbar spine surgery. The study group included 91 patients who had previous discectomy or laminectomy, 42 undergoing revision for adjacent segment degeneration and 38 patients undergoing revision for nonunion.
There were statistically significant improvements in back pain, leg pain and Oswestry Disability Index for all three groups of patients. The ASD and post-decompression patients demonstrated significant improvements in SF-36 PCS two years after surgery, while the nonunion patients did not.
A total of 29 percent of the post-decompression patients, 38 percent of the ASD patients and 29 percent of the nonunion patients reached the minimum clinically important difference threshold for the Oswestry Disability Index.
