The Efficacy of Unilateral Approach for Bilateral Decompression and Fusion in Spinal Stenosis with Segmental Instability
Keywords:
Transpedicular screw fixation, transforaminal lumbar interbody fusion, unilateral Approach for Bilateral Decompression & Fusion (UBD & Fusion)Abstract
Objective: To evaluate the efficacy of the unilateral approach for bilateral decompression and fusion (UBD &fusion) in spinal stenosis with segmental instability
Methods: Retrospective review of patients underwent surgery with unilateral approach for bilateral decompression
and fusion during April 2010 and April 2012 was performed. Fifty one patients were included in the study. The visual
analog scale (VAS), Neurogenic Claudication Outcome score (NCS), and Prolo Functional and Economic Scales (Prolo
score) were used to evaluate all patients preoperatively and at 1-year follow-up. The success of the intervetebral fusion
was assessed at 1 year after index surgery. Complications, including adjacent segmental degeneration and instrument
failure, were recorded in the postoperative assessment.
Results: Fifty one patients who underwent unilateral approach for bilateral decompression and fusion achieved
favorable outcome. The VAS, NCS and Prolo score had significantly improved at 1- year follow-up and the fusion rate
was 100 percent with no surgical complication.
Conclusions: Favorable results from the novel technique “Unilateral Approach for Bilateral Decompression and
Fusion” were found. This technique gives an adequate bilateral nerve roots decompression with high successful spinal
fusion rate.
