| 【Abstract】 Objectives: To investigate the influence of relationship between lowest instrumented vertebra(LIV) and sagittal stable vertebra(SSV) on the occurrence of distal junctional kyphosis(DJK) after posterior selective fusion in Lenke 1A scoliosis. Methods: A consecutive cohort of 153 patients with Lenke 1A scoliosis who had undergone posterior selective thoracic fusion was reviewed.
