Is There a Patient Profile That Characterizes a Patient With Adult Spinal Deformity as a Candidate for Minimally Invasive Surgery?
Abstract
Retrospective review.The goal of this study was to evaluate the baseline characteristics
of patients chosen to undergo traditional open versus minimally invasive surgery (MIS)
for adult spinal deformity (ASD).A multicenter review of 2 databases including ASD
patients treated with surgery. Inclusion criteria were age >45 years, Cobb angle minimum
of 20°, and minimum 2-year follow-up. Preoperative radiographic parameters and disability
outcome measures were reviewed.A total of 350 patients were identified: 173 OPEN patients
and 177 MIS. OPEN patients were significantly younger than MIS patients (61.5 years
vs 63.74 years, P = .013). The OPEN group had significantly more females (87% vs 76%,
P = .006), but both groups had similar body mass index. Preoperative lumbar Cobb was
significantly higher for the OPEN group (34.2°) than for the MIS group (26.0°, P <
.001). The mean preoperative Oswestry Disability Index was significantly higher in
the MIS group (44.8 in OPEN patients and 49.8 in MIS patients, P < .011). The preoperative
Numerical Rating Scale value for back pain was 7.2 in the OPEN group and 6.8 in the
MIS group preoperatively, P = .100.Patients chosen for MIS for ASD are slightly older
and have smaller coronal deformities than those chosen for open techniques, but they
did not have a substantially lesser degree of sagittal malalignment. MIS surgery was
most frequently utilized for patients with an sagittal vertical axis under 6 cm and
a baseline pelvic incidence and lumbar lordosis mismatch under 30°.

I have more than 25 years of experience treating patients of all ages with spinal
disorders. I have had an interest in the management of spinal disorders since starting
my medical education. I performed residencies in both orthopaedic surgery and neurosurgery
to gain a comprehensive understanding of the entire range of spinal disorders. My
goal has been to find innovative ways to manage the range of spinal conditions, straightforward
to complex. I have a focus on managing patients with complex s
