Abstract
Study Design
Retrospective, multicenter review of the spinopelvic parameters in young children with scoliosis.
Objectives
To describe sagittal alignment of the spine and pelvis in young children with scoliosis.
Summary of Background Data
The natural history of spinopelvic parameters has been defined for the first 10 years of life in normal children; however, they have not been described for children with scoliosis. Such information is important because these values can be used as a baseline for the assessment of radiographic outcomes after surgical intervention.
Methods
Seven measures of sagittal alignment were taken from standing lateral radiographs of 80 children with scoliosis (coronal Cobb angle greater than 50°) and compared with age-matched normal children described in the literature. Statistical analysis was performed using 2-tailed Student t tests (level of significance =.05) and Pearson correlation coefficient.
Results
Patients had a mean age of 4.8 years (range, 1 — 10 years) and a mean Cobb angle of 72.0° ± 16°. Mean sagittal spine parameters were sagittal balance (2.2 ± 4 cm), thoracic kyphosis (38.0° ± 20.8°), and lumbar lordosis (49.0° ± 16.6°). These values were similar to those of children without scoliosis. Mean sagittal pelvic parameters were: pelvic incidence (46.5° ± 15.8°), pelvic tilt (10.7° ± 13.6°), sacral slope (35.5° ± 12.1°), and pelvic radius (55.7° ± 21.3°). Pelvic incidence was not significantly different from that of age-matched
