Unilateral Tubular Approach for Bilateral Laminotomy vs Transforaminal Lumbar Interbody Fusion for Lumbar Spinal Stenosis

Abstract

Background: Endoscopic techniques is considered to be the standard tissue sparing approach for surgical advantages, rapid rehabilitation, and instability prevention. PEID techniques were introduced to treat lumbar spinal stenosis. However, its effectiveness and safety in the treatment of moderate and severe lumbar stenosis is uncertain.Methods: Between June 2014 and June 2016, patients suffering from lumbar spinal stenosis underwent a bilateral laminotomy through a unilateral tubular approach. Demographics, intraoperative data, and patient-reported outcomes were ascertainedResults:There were no significant differences in patient demographics between the two groups. The statistically significant improvements in leg and back VAS scores were reported on the ipsilateral and the contralateral side (p<0.05, respectively). Analysis of VAS and ODI scores demonstrated no significant differences in improvement on both groups. There were no difference in radiographical and intraoperative outcomes during the follow-up period. Conclusions: Regarding the intraoperative data, and patient-reported outcomes, the PEID is a safety, and efficacy minimally invasive technique. This observation suggests that the PEID techniques were excellent or showed good results.
