STUDY DESIGN This is a clinic-based cross-sectional study involving 2 health-related quality-of-life (HRQL) questionnaires. OBJECTIVES To compare the score distribution and reliability of the spinal deformity specific Scoliosis Research Society-22r (SRS-22r) questionnaire and the established generic Child Health Questionnaire-CF87 (CHQ-CF87), and to(More)
STUDY DESIGN This in vitro human cadaveric study tested the loss of thoracic motion segment flexion stiffness after sequential posterior upper instrumented vertebra anchor placement techniques and posterior column destabilization. OBJECTIVE This study was designed to determine the possible destabilizing effects of upper thoracic instrumentation anchor(More)
STUDY DESIGN Retrospective case series. OBJECTIVE To determine the prevalence of proximal junctional sagittal plane flexion increase after posterior instrumentation and arthrodesis. SUMMARY OF BACKGROUND DATA Increased flexion proximal to the junction of the instrumented and fused spinal region with the adjacent mobile spine seems to be a relatively(More)
The development of validated health-related quality-of-life instruments that are generic (Short Form-36) or disease-specific (Scoliosis Research Society [SRS]-22) allows physicians and researchers to measure the qualitative impact of spinal deformity and its treatment on their patients quantitatively. Although some further research may be needed in the area(More)
