Abstract Purpose As accurate and reproducible measurements of spinal curvature are crucial in the examination of patients with adolescent idiopathic scoliosis ( AIS ) , this systematic review aims to report on the reliability and validity of a range of inexpensive and easily administered anthropometric methods of postural asymmetry measurement in an AIS population , to inform practice in a clinical setting .
Prediction of Scoliotic Cobb Angle With the Use of the Scoliometer
Study Design A prospect i ve study was conducted in a young homogenous adolescent population , with the use of the scoliometer . Objectives To create a mathematic formula that provides the accurate Cobb angle of idiopathic scoliosis with the use of the scoliometer only . Summary of Background Data The scoliometer is an accepted method for detection and evaluation of scoliosis during screening programs . To the authors ' knowledge , there are no previous methods and formulas to estimate the approximate Cobb angle using only the scoliometer . Methods Several clinical ( scoliometer value , age , and sex ) and radiographic ( Cobb angle , Perdriolle of the apical vertebra , Risser iliac apophysis classification ) parameters from 442 ( 4.37 % ) of 10,109 screened adolescents who had a scoliometer value of at least 7 ° were taken and correlated using the simple and multiple linear regression analysis . Results Cobb angle and scoliometer value were statistically significantly correlated to each other . Two mathematic formulas were created to predict the Cobb angle of the thoracic and lumbar scoliosis , with similar sensitivity and accuracy . The thoracic and lumbar scoliometer values were statistic significantly correlated with the thoracic and lumbar Cobb angle ( P = 0.0254 and P = 0.0015 , respectively ) . The lumbar scoliometer value was significantly correlated with lumbar apical vertebra Perdriolle value . Also , the thoracic and lumbar Cobb angles were significantly correlated with thoracic and lumbar apical vertebra ( P = 0.0001 and P = 0.0015 , respectively ) . Conclusions In the present study , the authors have constructed two mathematic formulas , which provide accurately the scoliotic Cobb angle in young adolescents using only the scoliometer with a deviation of 5.63 ° for thoracic curves and 5.79 ° for lumbar curves . The authors recommend that all physicians engaged in scoliosis screening programs use the scoliometer based on the mathematic formulas that the authors developed . They believe that this method will reduce the cost of school screening programs , the overdiagnosis , and the unnecessary exposure to irradiation of this young population in the future
