BACKGROUND Radiographic evaluation for patients with scoliosis using Cobb method is the current gold standard, but radiography has radiation hazards. Several groups have recently demonstrated the feasibility of using 3D ultrasound for the evaluation of scoliosis. Ultrasound imaging is radiation-free, comparatively more accessible, and inexpensive. However, a reliable and valid 3D ultrasound sys...

Methods Twenty adolescents with scoliotic curvatures were chosen to participate in the study based on convenience, without predilection for gender, age, type or location. Images of the curvatures were examined by 15 trained observers to estimate the Cobb angle variability, as well as intraand inter-observer variations. Each image was measured three times at a minimum interval of one week betwee...

INTRODUCTION There is no large population size study on school screening for scoliosis in Malaysia. This study is aimed to determine the prevalence rate and positive predictive value (PPV) of screening programme for adolescent idiopathic scoliosis. MATERIALS AND METHODS A total of 8966 voluntary school students aged 13-15 years old were recruited for scoliosis screening. Screening was done by...

BACKGROUND Scoliogauge, has been developed for the measurement of ATR on iPhone smartphones. This study was to evaluate the reliability for the smartphone-aided ATR measurement method and to compare its reliability with that of the manual method. METHODS Sixty-four AIS patients with single thoracic or lumbar curve participated in this study. Of these patients, thirty-two patients had main tho...

Incorrect determination of the top or end vertebrae of a scoliotic curve causes measurement errors when using the Cobb method. Such problems are due to subjectivity. This study was performed to minimize subjectivity by using a curve fitting method. A digitally scanned posteroanterior radiographic image was used for each patient. User-defined midpoints of the curvature, which indicate the midpoi...

Late-onset (adolescent) idiopathic scoliosis is the commonest spinal deformity seen in our clinics. Like many orthopaedic deformities the degree of the condition determines its importance. When schoolchildren are examined many small inconsequential curves may be seen since it is difficult to keep a straight spine in the face of threedimensional growth for 20 years. The condition becomes progres...

STUDY DESIGN Interobserver and intraobserver reliability study of improved method to evaluate radiographs of patients with scoliosis. OBJECTIVE To determine the reliability of a computer-assisted measurement protocol for evaluating Cobb angle and King et al classification. SUMMARY OF BACKGROUND DATA Evaluation of scoliosis radiographs is inherently unreliable because of technical and human ...

Hypokyphosis is currently observed in thoracic idiopathic scoliosis. The use of sublaminar bands allows a good restoration of sagittal balance of the spine. The aim of the study was to provide a middle-term radiographic analysis of patients with adolescent idiopathic scoliosis with preoperative hypokyphosis treated by posterior arthrodesis with sublaminar bands. This retrospective study include...
