Patient Outcomes after Reoperation on the Lumbar Spine*

GEOFFREY STEWART, M.D.{dagger} and BARTON L. SACHS, M.D.{ddagger}, BOSTON, MASSACHUSETTS

Investigation performed at Tufts-New England Medical Center, Boston

A consecutive series of thirty-nine patients who had had a reoperation on the lumbar spine was followed for an average of forty-eight months (range, twenty-four to eighty-six months). The patients were evaluated with regard to pain, functional status, and work status. Twenty-eight patients (72 per cent) had a successful outcome, as determined by their ability to return to work, their lack of a need for narcotic analgesics, and their satisfaction with the operative result. Factors that were significantly associated with a successful outcome included a younger age (p < 0.02), working outside of the home (p < 0.05), an initial period of improvement after the previous (index) operation (p < 0.01), fewer spinal levels operated on previously (p < 0.05), and a revision procedure incorporating anterior interbody arthrodesis (p < 0.02).
