Laminectomy with and without spinal fusion.
This retrospective study evaluates two groups of patients surgically treated for a symptomatic, myelographically proven, herniated nucleus pulposus with a follow-up period from 3.5 to 16 years. One hundred thirty-four patients were treated with laminectomy, discectomy, and fusion (LDF) between the years 1972 and 1978; 49 returned for follow-up examination. Two hundred patients had laminectomies and discectomies between the years 1968 and 1981; 40 returned for follow-up evaluation. Two of the disc patients had a repeat laminectomy for recurrent disc herniation, thus totaling 42 laminectomies. Each patient was scored on a scale from zero to 100. The LDF cases had an average score of 70 points. The disc cases had an average score of 69 points. Three of the LDF cases (6%) and eight of the disc cases (19%) had had a second operation. Laminectomy patients have a significantly higher reoperation rate than patients who have had spinal fusion along with laminectomy; however, the authors were unable to evaluate the results in the two groups by the overall score.
