This study aims to investigate whether PI increases with age and to determine potential associated factors. 1510 patients with various spinal degenerative and deformity pathologies were enrolled, along with an additional 115 asymptomatic volunteers. Subjects were divided into six age subgroups with 10-year intervals. PI averaged 54.1° in all… CONTINUE READING
