Impact of Spinous Process Integrity on Ten to Twelve-Year Outcomes After Posterior Decompression for Lumbar Spinal Stenosis: Study of Open-Door Laminoplasty Using a Spinous Process-Splitting Approach

Conclusions: Osseous continuity between the spinous processes and the lamina after posterior decompression of the lumbar spine is important for maintaining the positive surgical benefit. Deleterious effects of osseous discontinuity on the outcomes were obvious at ten to twelve years, but not at two or four years. Level of Evidence: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.
