Improvement of Segmental Lordosis in Transforaminal Lumbar Interbody Fusion: A Comparison of Two Techniques.

Rice JW, Sedney CL, Daffner SD, Arner JW, Emery SE, France JC - Global Spine J (2015)

Bottom Line: Traditional TLIF versus cantilever TLIF results were compared, and radiographic outcomes were assessed.Patients undergoing the cantilever TLIF procedure had a significantly greater change in segmental lordosis and disk height compared with those who underwent the traditional procedure (p > 0.0001).Conclusions The cantilever TLIF technique can lead to greater change in segmental lordosis based upon radiographic outcomes.

ABSTRACT
Study Design Retrospective review. Objective The purpose of this study was to determine the radiographic impact of a transforaminal lumbar interbody fusion (TLIF) versus a cantilever TLIF technique on segmental lordosis, segmental coronal alignment, and disk height. Methods A retrospective review was done of all patients undergoing TLIF procedures from 2006 to 2011 by three spine surgeons. Traditional TLIF versus cantilever TLIF results were compared, and radiographic outcomes were assessed. Results One hundred one patients were included in the study. Patients undergoing the cantilever TLIF procedure had a significantly greater change in segmental lordosis and disk height compared with those who underwent the traditional procedure (p > 0.0001). Conclusions The cantilever TLIF technique can lead to greater change in segmental lordosis based upon radiographic outcomes.

FI1500062-1: The kidney-shaped spacer (left) and straight spacer (right).

Mentions: One technique involves placing a kidney-shaped spacer (Fig. 1) as anteriorly as possible (preferably on the apophyseal ring) in the disk space. This technique was introduced by Anand et al and is termed a “cantilever” TLIF, or c-TLIF.12 The second technique involves the use of a straight spacer (Fig. 1) placed obliquely through the disk space. Our goal was to determine if the c-TLIF technique improved radiographic DH and segmental alignment when compared with the straight cage method of TLIF.
