Can unilateral-transforaminal lumbar interbody fusion replace the traditional transforaminal lumbar interbody fusion procedure for lumbar degenerative disc diseases?: a single center matched case-control mid-term outcome study

UPSF-TLIF is comparable to BPSF in terms of patient-reported clinical outcomes, fusion rates, and complication rates while being superior in terms of lesser ASD. UPSF enables radiologically and clinically significant contralateral indirect neural foraminal decompression and canal decompression without disturbing the contralateral side anatomy, unlike BPSF.
