Leg Length Discrepancy and Adolescent Idiopathic Scoliosis: Clinical and Radiological Characteristics

"A scoliometer used as an indirect and quantitative method to evaluate LLD for the first time in this study, and described it as Leg Length Discrepancy Scoliometer Test. Scoliometer were used on Adams' forward bending position and the level of the pelvis accepted as equal when the scoliometer degree pointed zero on the sacral basis (angle of trunk rotation on sacrum). When considering pelvis level is high on the longer side and is low on the shorter side, if the angle of the scoliometer on the sacrum is negative (slope to the left), the left extremity was considered as shorter. In order to determine its correlation with an indirect method, scoliometer degree on the sacral basis was recorded then wooden blocks were added to the unequal leg side on the sacral basis until the pelvic equality was achieved on the scoliometer. Afterward, a correlation between the first measurement of ATRsacrum and the height of the wooden block which provides ATRsacrum to reach zero was investigated."
