Comparative characteristics of sagittal balance in normal children and with spondylolisthesis

BACKGROUND: The measurement of sagittal parameters is an important part preoperative planning and also used to evaluate the results surgical treatment. It known that in spondylolisthesis (especially at high degrees) spine differ from those healthy people. difference spinal-pelvic children adults without orthopedic pathology has been proven. One tasks treatment restoration balance or its maximum approximation normal values. However, today there no single accepted norm for children, therefore, question optimal tactics remains open.
 AIM: To determine with spondylolisthesis.
 MATERIAL AND METHODS: A retrospective analysis postural radiographs 68 was performed. Patients were divided into 2 groups: group I 43 patients 8 17 years old spinal pathology. Group II 25 old. For each patient, main pelvic (PT; PI; SS; LL; PI-LL; TK) measured statistical data performed.
 RESULTS: study proved (PI, PT, SS, LL, TK, PI-LL) pathological deformities column are statistically significantly different. Also, significant differences between adolescents SFD, PI-LL). In grade spondylolisthesis, thoracic kyphosis lumbar lordosis reduced, which should be assessed as a compensatory mechanism maintaining vertical position body. Children characterized by higher PI value.
 CONCLUSION: different, correct planning, it necessary establish children. take account value may etiological factor this disease. existing formulas measuring caution, because can lead unreliable theoretical values LL TK. cause imbalance not only degrees but tight hamstrings.
