EVALUATION OF CONDITIONS OF SPINO-PELVIC RATIOS IN CHILDREN WITH BILATERAL HIGH RIDING TROCHANTER
A number of diseases of the hip joint is accompanied by a multi-plane deformation of the femoral component of the hip joint, resulting in a high riding trochanter. Assessment of the state of sagittal spino-pelvic ratios in children and adults with various pathologies of the vertebral column and hip joints allows us to predict the development of degenerative processes in them, at the same time, there are no data available in the world literature on the state of sagittal balance in children with bilateral high riding trochanter. Purpose - to evaluate the indicators of sagittal spino-pelvic ratios and determine the type of vertical posture in children with bilateral high riding trochanter. The study included 30 patients (60 hip joints) aged 13 to 16 years (14.5 ± 0.9) with bilateral high riding trochanter. All patients underwent a standard orthopedic examination with a Harris hip score and Oswestry questionnaire. All patients underwent radiometry of indicators characterizing the state of the hip joint and sagittal spino-pelvic ratios. Clinical and radiological changes in sagittal spino-pelvic ratios are manifested in lumbar hyperlordosis, which occurs as a result of the formation of excessive pelvic anteversion. A strong positive correlation was found between the height of the great trochanter and the sacral slope - the Pearson coefficient was 0.69. For children with high riding trochanter characteristically increase in the values of global lumbar lordosis( GLL), sacral slope (SS), a decrease in the values of pelvic tilt (PT) and a shift of the sagittal vertical axis (SVA) posterior to the cape of the sacrum. This x-ray pattern corresponds to the IV (hyperlordotic) type of vertical posture according to P. Roussouly.
