Before correction surgery, physical examination, x\u2010ray, CT, MRI and Blood HLA\u2010B27 examination were performed and a series of radiological parameters, including the degree of kyphosis and the T1\u2010pelvic angle (TPA), were measured. Several days after surgery (Distal PSO was used), we performed examinations to check the patient's physical condition which showed the patient recovered remarkably. CTA was done, indicating that the patient's aorta moved anteriorly with the osteotomy side undamaged. A series of morphological parameters were measured again, including TPA, LL, and TK. CT and MRI were performed again, reflecting significant bone\u2010to\u2010bone fusion and successful recovery.
