Minimum 20 Years Long-term Clinical Outcome After Spinal Fusion and Instrumentation for Scoliosis: Comparison of the SRS-22 Patient Questionnaire With That in Nonscoliosis Group.

Study Design: A retrospective minimum 20-year follow-up study using 4 standard self-administered questionnaires, one of which, the SRS-22 was also administered to control groups.

Objective: To evaluate long-term postoperative pain and other clinical outcomes of scoliosis correction and fusion surgery with Harrington instrumentation using Moe square-ended rods for better preservation of sagittal alignment.

Summary Of Background Data: Only a few long-term outcome studies have used standardized and validated self-administered tools, and no studies have established SRS-22 control data within their own population.

Significance of peak height velocity as a predictive factor for curve progression in patients with idiopathic scoliosis.

Background: Much attention has been paid to peak height velocity (PHV) as a possible predictor of curve progression in patients with idiopathic scoliosis (IS). The aim of this study was to analyze the relationship between the magnitude of the Cobb angle at PHV and scoliosis progression, defined as having surgery prior to skeletal maturity in female patients with IS.

Methods: A retrospective review identified 56 skeletally immature female IS patients who were followed until maturity.

Analysis of the Anterior Trunk Symmetry Index (ATSI). Preliminary report.

Spine deformations and faulty posture may be evaluated by assessing trunk surface deformation. POTSI index (Posterior Trunk Symmetry Index) was introduced in 2003 to assess asymmetry of the trunk seen from the back. However, deformations may also affect the anterior surface of the trunk and this can be noticed more easily by the patient owing to the visual accessibility of the anterior surface.

Height velocity curves in female patients with idiopathic scoliosis.

Following identification of peak height velocity (PHV) by a recent study as a possible prognostic factor for curve progression in patients with idiopathic scoliosis (IS), the aim of this study was to investigate PHV curves in Japanese female patients with IS. The study subjects were 20 skeletally immature IS patients who were followed until maturity. The mean age and the mean pubertal status at the initial visit were 9.

Super Hybrid Method of scoliosis correction: minimum 2-year follow-up.

We applied a new surgical technique utilizing conventional hybrid instrumentation to achieve better correction of trunk deformity in adolescent idiopathic scoliosis. The purpose of this study is to introduce our "Super Hybrid Method" and to analyze the results at minimum 2-year follow-up. The technique consists of rib mobilization (2006), a rod rotation maneuver (1997) and a hook rotation maneuver (2007).

Factors of thoracic cage deformity that affect pulmonary function in adolescent idiopathic thoracic scoliosis.

Study Design: This clinical study examined the association between pulmonary function and thoracic cage deformities in scoliosis.

Objective: To determine the factors in spinal and thoracic cage deformities that affect pulmonary function in scoliosis.

Summary Of Background Data: Pulmonary function in scoliosis has generally been evaluated in terms of lateral spinal curvature.

Posterior circumferential decompression for late onset paraparesis caused by kyphotic deformity due to infantile tuberculosis--case report.

A 46-year-old male presented with late onset of paraparesis caused by kyphotic deformity due to infantile tuberculosis. A posterior circumferential decompression was performed from the sixth thoracic to the eighth thoracic levels. His neurological status improved with no evidence of kyphosis progression at the last follow up (2 years 5 months postoperatively).
