Minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) is among the most commonly performed surgical procedure to treat lumbar degenerative disorders.
We retrospectively reviewed medical records for all adult patients with a body mass index (BMI) ≥40 kg/m<sup>2</sup> who underwent 1- to 2-level MIS TLIF for degenerative disease between February 2009 and February 2014 at a single institution and compared them to age-matched normal-weight patients (BMI 20-25 kg/m<sup>2</sup>).
From March 2009 to September 2016, 117 patients who underwent a single-level MIS-TLIF surgery for lumbar degenerative disease were enrolled in this retrospective study.
Microendoscopy-assisted minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) is an advantageous method for treating lumbar degenerative disease; however, some patients show contralateral radiculopathy postoperatively.
The purpose of this study was to investigate the feasibility and effectiveness of using a narrow-surface fusion cage in full endoscopic minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) for the treatment of lumbar degenerative disease.
