Minimally invasive transforaminal lumbar interbody fusion with unilateral pedicle screw fixation (UNILIF): morbidity, clinical and radiological 2-year outcomes of a 66-patient prospective series

Abstract

Purpose

To assess clinical and radiological outcomes at 2-year follow-up of one-level minimally invasive transforaminal interbody fusion with unilateral pedicle screw fixation (UNILIF) in the treatment of stable lumbar degenerative diseases.

Methods

From January 1, 2012 to January 31, 2013, we prospectively collected clinical and radiological data on patients with stable degenerative lumbar disease managed by UNILIF in a single institution. Preoperatively and at 2 years, we recorded ODI, SF-12, Quebec and VAS. Interbody fusion was analyzed on radiography and on a CT scan, and sagittal balance was tested on full spine radiography.

Results

Mean operation time was 74.5 min ± 16.8, mean blood loss was 130.8 ml ± 210.9. At 2 years, ODI, SF-12, Quebec and VAS were significantly improved (p > 0.005).The fusion rate was 96.8% on radiographic analysis and was 87.9% on CT scan analysis.

Conclusions

One-level UNILIF constitutes an effective alternative for management of stable lumbar degenerative diseases.
