Age-Related Dynamics of Roentgenologic Characteristics of Pelvis and Spine Osseous Growth Activity in Patients with Idiopathic Scoliosis

Roentgenologic examination of pelvis and spine osseous growth activity was performed with the purpose to determine the peculiarities of its age-related dynamics in patients with idiopathic scoliosis. Total number of 2006 patients (1770 females and 236 males) was examined. Age if patients ranged from 4 to 20 years. Severity of spine deformity corresponded to I-IV stages. Activity of pelvis growth was assessed by Risser test (R), of spine growth - by Sadof'eva test (S).Results of those tests were divided into three groups of osseous growth activity state: group of active growth included indices R-0 - R-III and S-0 - S III, group of stabilized growth - R-IV and S-IV, group of completed growth - R-V and S-V. It was stated that in idiopathic scoliosis pelvis and spine came into periods of apophyseal ossification, synostosis and osseous growth completion at later age terms than at norm - the lag made up from 1 to 4 years. It was also detected that in given pathology the spine itself started and completed its physiologic growth with 1-3 years delay as compared with pelvic bones. The obtained results indicated that in idiopathic scoliosis Risser test results should be considered as an objective but indirect information on spine growth activity. Direct objective precise information on the spine growth activity could be obtained by Sadof'eva test that reflected directly the stage of leading affected organ development in that pathology.
