Item Open Access Comparison of Structural Disease Burden to Health-related Quality of Life Scores in 264 Adult Spinal Deformity Patients With 2-Year Follow-up: Novel Insights into Drivers of Disability.(Clinical spine surgery, 2017-03) Bakhsheshian, Joshua; Scheer, Justin K; Gum, Jeffrey L; Horner, Lance; Hostin, Richard; Lafage, Virginie; Bess, Shay; Protopsaltis, Themistocles S; Burton, Douglas C; Keefe, Malla; Hart, Robert A; Mundis, Gregory M; Shaffrey, Christopher I; Schwab, Frank; Smith, Justin S; Ames, Christopher P; International Spine Study Group (ISSG)Study design
This is a review of a prospective multicenter database.Objective
To investigate the relationship between preoperative disability and sagittal deformity in patients with high Oswestry Disability Index (ODI) and no sagittal malalignment, or low ODI and high sagittal malalignment.Summary of background data
The relationship between ODI and sagittal malalignment varies between each adult spinal deformity (ASD) patient.Methods
A prospective multicenter database of 365 patients with ASD undergoing surgical reconstruction was analyzed. Inclusion criteria entailed: age 18 years or above and the presence of spinal deformity as defined by a coronal Cobb angle≥20 degrees, sagittal vertical axis (SVA)≥5 cm, pelvic tilt (PT) angle≥25 degrees, or thoracic kyphosis≥60 degrees. Radiographic and health-related quality of life (HRQOL) variables were examined and compared, preoperatively and at 2-year postoperative follow-up. Group 1 (low disability high sagittal-LDHS) consisted of ODI<40 and SVA≥5 cm or PT≥25 degrees or pelvic incidence-lumbar lordosis≥11 degrees and group 2 (high disability low sagittal-HDLS) consisted of ODI>40 and SVA<5 cm and PT<25 degrees and pelvic incidence-lumbar lordosis<11 degrees.Results
Of 264 patients with follow-up, 58 (22.0%) patients were included in LDHS and 30 (11.4%) were included in HDLS. Both groups had similar demographics and preoperative coronal angles. HDLS had worse baseline HRQOL for all measures (P<0.05) except leg and back pain. HDLS had a higher rate of self-reported leg weakness, arthritis, depression and neurological disorder. Both groups had similar 2-year improvements in HRQOL (P>0.05), except only HDLS had a significant Scoliosis Research Society Mental improvement and a significantly higher rate of reaching minimal clinically important differences in Scoliosis Research Society Mental scores (P<0.05).Conclusions
There is an association of worse baseline HRQOL measures, weakness, arthritis, and mental disease in HDLS. Furthermore, HDLS patients demonstrated similar improvements to LDHS. However, HDLS had greater improvements in the mental domains, perhaps indicating the responsiveness of the mental disability to surgical treatment.Level of evidence
Level III.Item Open Access Post-operative bracing following adult spine deformity surgery: Results from the AO Spine surveillance of post-operative management of patients with adult spine deformity.(PloS one, 2024-01) Kato, So; Smith, Justin S; Driesman, Devin; Shaffrey, Christopher I; Lenke, Lawrence G; Lewis, Stephen J; AO Spine Knowledge Forum DeformityStudy design
Cross-sectional international survey with a literature review.Objectives
While some surgeons favor spine bracing after surgery for adult spine deformity (ASD) to help prevent mechanical failures, there is a lack of evidence. The objective of the present study was to better understand the current trend in the use of bracing following ASD surgery based on an international survey.Methods
An e-mail-based online survey was conducted among over 6000 international AO Spine members regarding the post-operative management of patients with ASD. The details of brace prescription, indications and influencing factors were solicited. Descriptive data were summarized based on different demographic groups and fusion levels for the responding surgeons who annually perform at least 10 long-segment fusions of >5 levels extending to the pelvis.Results
A total of 116 responses were received, including 71 surgeons (61%) who used post-operative bracing for >5 levels of long fusion. The most common reason for bracing was pain management (55%) and bone quality was the strongest influencing factor (69%). Asia-Pacific surgeons had the highest rate of bracing (88%), while North American surgeons had the lowest (45%). The most common type of brace used were TLSO for cases with an uppermost instrumented vertebra (UIV) in the low- or mid-thoracic spine and a cervical brace for UIV at T1-3. The majority (56%) used bracing for 6-12 weeks after surgery.Conclusions
The present survey demonstrated significant interest in bracing following ASD surgery, however, there is substantial variability in post-operative bracing practice. A formal study on the role of bracing in ASD surgery is needed.
