For people with spinal deformity, increased sagittal vertical axis (SVA) is substantially correlated with pain and disability. Patients who have flatback deformity (pelvic incidence-lumbar lordosis [PI-LL] mismatch > 10°) as a result of sagittal spinopelvic malalignment (SSM) are nonetheless sagittally compensated with normal SVA. For SSM patients with flatback deformity and normal SVA, there are few data. For patients with compensated (SVA 5 cm and PI-LL mismatch > 10°) and decompensated (SVA > 5 cm) SSM, it is the goal to compare baseline impairment and treatment outcomes.
The conclusion was that The level of handicap in compensated SSM patients with flatback deformity brought on by PI-LL mismatch but normal SVA is underestimated, compared to decompensated SSM patients with raised SVA. Similar radiographic and HRQOL score improvements for patients in both groups were seen following surgical correction of SSM. SSM evaluation ought to go beyond SVA assessment. A main rationale for surgery in individuals with concordant pain and impairment is PI-LL mismatch, which needs to be assessed in SSM patients.
<h3>What is flatback deformity?</h3>
When the lordosis, kyphosis, or both are lost, flatback syndrome develops, causing the spine to become straight. People with flatback syndrome frequently have trouble standing up straight and appear bent forward.
