Popis: Abstract Background The surgical procedure of vertebral column decancellation (VCD) has been increasingly performed in orthopaedic surgery for those with spinal deformity. To investigate the results of single-segment VCD performed at different vertebra for correcting thoracolumbar kyphosis in ankylosing spondylitis (AS) and to guide the osteotomy strategy. Methods Eighty-six AS patients (77 males, 9 females) having thoracolumbar kyphosis underwent single-segment VCD (ranging from T12 to L3) between January 2016 and September 2019 were enrolled and divided into four groups according to the osteotomy vertebra: T12 in 9 cases (Group A), L1 in 15 cases (Group B), L2 in 47 cases (Group C), and L3 in 15 cases (Group D). Demographics, operational data, radiological and clinical data were compared among the four groups. Results All patients had significant improvements in spinopelvic alignments and health-related quality of life after correction surgeries. Having the similar demographics, patients in the group C obtained the maximum local kyphosis and global kyphosis correction of 45.05° ± 9.07° (P
