Comparative outcomes of three kinds of transforaminal interbody fusion technique in the treatment of single segment lumbar degenerative disease

Abstract

Objective: To compare the clinical outcomes among three kinds of transforaminal interbody fusion technique in the treatment of single segment lumbar degenerative disease. Methods: From October 2012 to November 2014, a total of 67 cases of lumbar degenerative disease of single segment underwent surgical intervention were retrospectively analyzed, including 19 cases by mis- transforaminal lumbar interbody fusion(TLIF), 25 cases by mini-open TLIF and 23 cases by open TLIF.Blood loss, surgical time, fluoroscopy time and hospital costs were recorded.Pre- and postoperative back pain was assessed with visual analogue scale (VAS), and lumbar function was evaluated with Oswestry disability index (ODI). Results: mis-TLIF group need more surgical time, fluoroscopy time and more hospital costs when compared to mini-open TLIF group and open TLIF group (P<0.05), but no significant difference between mini-open TLIF group and open TLIF group (P>0.05). mis-TLIF group tended to lose less blood than mini-open TLIF group(P<0.05), and mini-open TLIF group lose less blood than open TLIF group (P<0.05). There is no significant difference of the change of ODI among three groups (P>0.05). mis-TLIF group and mini-open TLIF group was superior to open TLIF group in VAS of the second day postoperative [(3.2±1.6) scale, (3.4±1.5) scale vs(5.8±1.4)scale](P<0.05). Conclusion: mis-TLIF, mini-open TLIF and open TLIF can all get satisfactory clinical outcomes in the treatment of single segment lumbar degenerative disease.mis-TLIF and mini-open TLIF was superior to open TLIF in blood loss, early postoperative recovery.Compared with mis-TLIF, mini-open TLIF reduce the fluoroscopy time and hospital costs, and also has a shorter learning curve.
