Adolescent idiopathic scoliosis (AIS) can continue to progress after skeletal maturity. Once the progression is severe, posterior spinal fusion (PSF) is the gold standard for surgical treatment. While effective in achieving curve correction, PSF is associated with many problems, including loss of spinal flexibility, uncorrected sagittal deformity, and adjacent segment disease. We present a case of a 50-year-old woman with a documented 38º thoracic curve as a late teen who experienced curve progression after skeletal maturity to >70 ° and underwent Anterior Scoliosis Correction (ASC), a motion-preserving scoliosis correction surgery. Her progressive curve improved from 71º Lenke 1A main thoracic curve to 28°, with a 59% correction being maintained within 5° (33°) at 7 years. She also obtained a 50% correction of her compensatory lumbar curve and correction of hypokyphosis from 2.4° to 23° at 7 years. Along with improvement of her thoracic kyphosis, her lumbar lordosis decreased to a normal range of 60° from 70°, giving her better overall alignment. This case report suggests that motion preserving surgical treatment may be considered for some select adult patients with progressive scoliosis.
