Multicenter Study Clinical Trial
A multicenter study analyzing the relationship of a standardized radiographic scoring system of adolescent idiopathic scoliosis and the Scoliosis Research Society outcomes instrument.
A multicenter study examining the association between radiographic and outcomes measures in adolescent idiopathic scoliosis. ⋯ The Cobb angle measure of the major deformity has a small, but statistically significant, correlation with the reported Total Pain, General Self-Image, and General Function as measured by the Scoliosis Research Society outcomes instrument. None of the radiographic measures in this population correlated with postoperative domain scores of the Scoliosis Research Society outcomes tool.

Multicenter Study Clinical Trial
A multicenter study of the outcomes of the surgical treatment of adolescent idiopathic scoliosis using the Scoliosis Research Society (SRS) outcome instrument.
A multicenter study of the outcomes of the surgical treatment of adolescent idiopathic scoliosis using the Scoliosis Research Society Questionnaire (SRS 24). ⋯ Preoperative pain exists in our adolescent scoliosis population. Pain scores were improved in our study population at the 2-year postsurgical follow-up. Statistically significant improvements were likewise seen in the General Self-Image, Function From Back Condition, and Level of Activity domains. The present study demonstrates the ability of surgery to improve the outcome of patients afflicted with adolescent idiopathic scoliosis.

Comparative Study Clinical Trial
Evaluation of ventilatory efficiency during exercise in patients with idiopathic scoliosis undergoing spinal fusion.
A prospective evaluation of ventilatory function following spinal fusion in adolescent idiopathic scoliosis. ⋯ Improvement in ventilatory efficiency during exercise does not occur in the majority of patients with adolescent idiopathic scoliosis following spinal fusion and thus cannot be relied on to foster increases in aerobic activity.

Radiographic markers in spondyloptosis: implications for spondylolisthesis progression.
Radiographic analysis of spinopelvic morphology and posterior element dysplasia in spondyloptosis. ⋯ Prognostic factors for spondylolisthesis progression, such as percent of slippage, do not identify lower-grade slips at risk for progression. Progression is linked to increased shear stress across the lumbosacral junction and inability to resist it. Increased stress is related to increased verticality of the lumbosacral joint, which is individually predetermined by pelvic incidence and sacral anatomy. Pelvic incidence is fundamental in determining sagittal spine curvature required for economic spinopelvic balance. Pelvic incidence is independent of adaptive changes in higher-grade spondylolisthesis. Pelvic incidence in our spondyloptosis series (76 degrees) is higher than in normal (48.2-53.2 degrees ) and low-grade spondylolisthesis (64.5 degrees). Posterior element dysplasia decreases mechanical resistance to lumbosacral shear stress. Incidence of dysplasia in our series (62%) is higher than that reported in low-grade spondylolisthesis. Analysis of pelvic incidence and posterior element dysplasia may aid in estimation of risk for progression of spondylolisthesis.

Forty-four consecutive thoracic idiopathic adolescent curves surgically treated between 1995 and 1999 at one institution were analyzed. All were thoracic curves; there were no lumbar curves, double major curves, or triple major curves. ⋯ "Satisfactory" results were obtained in 44 patients treated with this technique. The complication rate was low and the fusion rate was high. Posterior treatment as described above produces reasonable and dependable results.
