Abstract
Background
To investigate and compare the surgical outcomes of short and thoracopelvic corrective
fusion with our two-stage technique using lateral lumbar interbody fusion (LLIF) and
posterior open surgery.
Methods
Consecutive patients with adult spinal deformities who underwent a planned two-stage
anterior-posterior surgery, using LLIF for the first stage and posterior open corrective
fusion for the second stage, with a minimum of 2 years of follow-up were included.
Patients who underwent lumbar or lumbosacral corrective fusion and thoracopelvic corrective
fusion were categorized into the short group and thoracopelvic groups, respectively.
We investigated the spinopelvic parameters and patient-reported outcome measurements.
Results
Seventy-four consecutive patients (8 men, 66 women; average age, 70.0 years) were
included. Ten patients underwent short corrective fusion following significant improvements
in the symptoms and radiographic parameters post-LLIF. Several preoperative spinopelvic
parameters were better in the short group. Compared to the thoracopelvic group, those
who underwent short fusion had a poorer alignment 2 years postoperatively but with
comparable results and a significantly higher function score on the Scoliosis Research
Society–22 r (SRS-22r) questionnaire. The mean Oswestry Disability Index and SRS-22r
scores significantly improved during the 2-year postoperative follow-up in both the
groups.
Conclusions
Short corrective fusion can be considered in patients whose symptoms and radiographic
parameters significantly improve following LLIF. Patients who undergo short fusion
with LLIF application have poorer alignment than those who undergo thoracopelvic fusion
2 years postoperatively; however, the results are comparable, and the function score
is significantly improved.
