ABSTRACT
OBJECTIVE:
The authors have recently been using a surgical technique of minimally invasive direct lateral interbody fusion (DLIF) for correcting of coronal imbalance. The purpose of this study was to evaluate the surgical outcome and complication of DLIF.METHODS:
We undertook retrospective analysis of a consecutive series of 8 DLIF procedures in Degenerative lumbar spine disease since May 2011. Four patients underwent DLIF only, and the others underwent combined DLIF and posterior fixation. Data on intra- and postoperative complications were collected. The pre- and postoperative X-rays were reviewed. We investigated coronal deformity, Cobb's angle, and apical vertebral translation (AVT). The mean follow-up period was months with a range of 2 to 8 months.RESULTS:
A mean preoperative coronal Cobb's angle was 21.8degrees (range 11.5-32.4degrees). Following after DLIF, the mean Cobb's angle was decreased to 13.0degrees (range 2.9-21.5degrees). Following additional posterior screw fixation, mean Cobb's angle was further decreased to 7.4degrees (range 2.9-13.2degrees). A mean preoperative AVT was 2.0 cm(range 0.6-3.5 cm), and improved to 1.4 cm(range 0.3-2.4 cm) and 0.8 cm(range 0.2-1.8 cm) postoperatively (DLIF and, posterior fixation respectively). One patient (12.5%) showed cage migration during follow-up period. Two patients (25%) developed motor weakness, and 4 patients (50%) experienced postoperative thigh paresthesias or dysesthesias. During follow up period, motor weakness had resolved in 1 patient. Sensory symptoms were improved in all patients at the last follow-up.CONCLUSION:
Degenerative lumbar disease can be effectively corrected by DLIF with acceptable complications.
