Minimally invasive transforaminal lumbar interbody fusion (TLIF) as a short
fusion is widely accepted among the spine surgeons. However in the long fusion
for degenerative kyphoscoliosis, corrective spinal fixation by an open method is
thought to be frequently selected. Our objective is to study whether the
mini-open TLIF and corrective TLIF contribute to the improvement of the spinal
segmental and global alignment. We divided the patients who performed lumbar
fixation surgery into three groups. Group 1 (G1) consisted of mini-open TLIF
procedures without complication. Group 2 (G2) consisted of corrective TLIF
without complication. Group 3 (G3) consisted of corrective TLIF with
instrumentation-related complication postoperatively. In all groups, the lumbar
lordosis (LL) highly correlated with developing surgical complications. LL
significantly changed postoperatively in all groups, but was not corrected in the
normal range in G3. There were statistically significant differences in
preoperative and postoperative LL and mean difference between the pelvic
incidence (PI) and LL between G3 and other groups. The most important thing not
to cause the instrumentation-related failure is proper correction of the sagittal
balance. In the cases with minimal sagittal imbalance with or without coronal
imbalance, short fusion by mini-open TLIF or long fusion by corrective TLIF
contributes to good clinical results if the lesion is short or easily
correctable. However, if the patients have apparent sagittal imbalance with or
without coronal imbalance, we should perform proper correction of the sagittal
spinal alignment introducing various technologies.
