Cost Effectiveness of Nonoperative Management for Adult Spinal Deformity Associated With Low Grade Scoliosis: A Prospective Pilot Study to Evaluate Disease Burden and Longitudinal Study Feasibility

Quantify the efficacy and cost of nonoperative treatment modalities used for adult spinal
deformity.

1. Identify disease burden associated with adult spinal deformity (ASD) using quality
adjusted life year (QALY) analysis.

2. Identify disease burden of specific demographic and radiographic features associated
with ASD.

3. Compare disease burden of ASD to other musculoskeletal and non-musculoskeletal
diseases.

4. Identify efficacy of specific nonoperative treatment modalities to treat ASD and
identify specific clinical and radiographic features of ASD responsive to nonoperative
treatment modalities.

5. Compare QALY and ICER values for different ASD nonoperative treatment modalities to
previously established QALY and ICER for values for operative and nonoperative
treatment modalities for degenerative hip and knee disease, coronary artery disease,
insulin dependent diabetes, and hypertension.

6. Evaluate the cost and work hours associated with data collection and minimum 85%
patient follow up.

7. Evaluate patient characteristics associated with poor patient compliance for study
follow up including demographic, radiographic and HRQOL values and for reasons for
cross-over to operative treatment for ASD.

8. Establish standardized data collection methodology for economic based outcome studies
based upon patient demographics and HRQOL values.

Inclusion Criteria:

1. Age 40-75 years of age at the time of enrollment.

2. ODI ≥30

3. Adult degenerative or idiopathic lumbar scoliosis 10-40° as measured by the Cobb
angle technique

4. Sagittal plane deformity by SRS Schwab classification with at least one modifier ++
or two modifiers + and associated coronal cobb of at least 10 degrees

Exclusion Criteria:

1. Adult degenerative or idiopathic scoliosis with a curvature of the spine measuring
<10 degrees or >40 degrees

2. Diagnosis of scoliosis other than degenerative or idiopathic (i.e. neuromuscular,
congenital, etc.)

3. Cardiopulmonary disease or comorbidities that preclude surgical intervention

4. Patient not deemed surgical candidate by treating surgeon

5. Patient unwilling to commit to monthly phone interviews or completion of necessary
questionnaires or inability to return for defined follow up time points. Patients
unwilling to comply with study protocol will not be offered enrollment into the
study, regardless of meeting inclusion criteria.
