Abstract:
[Objective]To investigate the correlation of sagittal parameters in L5~S1 isthmic spondylolisthesis and its clinical manifestation.[Method]Seventy-six patients with L5~S1 isthmic spondylolisthesis were treated between January 2000 and December 2005,there were 32 males and 44 females with the age between 12 and 68 years.The lateral standing radiographs of the spine and pelvis were analyzed retrospectively.Radiographic parameters measured including pelvic incidence(PI),sacral slope(SS),lumbar lordosis(LL),lumbosacral angle(LSA)and grade of spondylolisthesis.All measurements were done by the same individual and compared to those of a cohort of 30 normal subjects.Students test was used to compare the parameters between the curve types and Pearsons correlation coefficients were used to investigate the association between all parameters(P
