Coronal and Sagittal Plane Spinal Deformities Correlating with Back Pain and Pulmonary Function in Adult Idiopathic ScoliosisJACKSON, ROGER P., MD*; SIMONS, EDWARD H., MD†; STRIPINIS, DANIEL, MA, MSc‡Spine: December 1989 - Volume 14 - Issue 12 - p 1391-1397 Original Article: PDF Only Buy Abstract Author InformationAuthors One hundred one referred adult patients (ages 20-63; mean, 36 years) with painful idiopathic scoliosis were evaluated. None. had prior surgical treatment. Severity of pain was graded and localized over radiographic deformities in the coronal and sagittal planes. Radiographic changes in primary as well as full and fractional compensatory curves were studied. Degrees of scoliosis, percent correction on side bending, vertebral body rotation at curve apex, spinal balance, and lateral olisthesis in the coronal plane, degenerative disc disease, and other degenerative changes in all curves were measured and graded in both the coronal and sagittal planes. Lordosis and kyphosis were measured on all standing sagittal radiographs. Forty-one patients had pulmonary function studies. Multiple variable statistical analysis (Spearman correlation coefficients) of the data found fractional lumbosacral curves most painful and disabling. Scoliosis greater than 40° and kyphosis greater than 50° correlated with increasing pain and decreasing forced vital capacity. Reduction in forced vital capacity also correlated with curve rigidity. Rotation correlated closely with degrees of scoliosis (r=0.70; P<0.0001) and had the highest correlation with pain (r=0.59; P<0.0001) of all radiographic findings and deformities studied. *From the North Kansas City Hospital, Kansas City, Missouri †From the State University of New York at Buffalo, Buffalo General Hospital, Buffalo, New York ‡From the Department of Statistics, University of Toronto, Toronto, Ontario, Canada © Lippincott-Raven Publishers.
