Objectives: The aim of present work was determination the part of densitometry as diagnosis criterion of osteoporosis display in children with orthopedic pathology.

Methods: 42 children with orthopedic diseases (congenital hip dislocation) at the age from 4 to 12 years, being in need of long immobilization, medication, limitation of physical load, were treated in the clinic of RITO the method of double energetic X-ray absorptiometry (DXA) for different age periods MBT was determined on the apparatus "Stratos" (France). Physical development was determined on the centile tables.

Results and Conclusion: The taken data revealed harmonious physical development in 52% children, disharmonious one was in 48% Influence of hypodinamics was reflected on mental development, children had some physically retardation from their coevals, muscular masses were activated in parts far from the places of necessary immobilization.(MBT) decrease, according to DXA data, was revealed in 53% children, among those osteopenia was determined in 35% patients, and osteoporosis was in 17 %, by that the given decrease was diagnosed more often in girls than in boys, without essential true difference, being treated on the occasion of congenital hip dislocation.(CHD) Considering the content of mineral thickness for bone, it is necessary to mark, that the index of middle mineral content in bone tissue is true lower in children with low height (tu 18%), than in children with normal development of height parameters (to 0.2%). The same regularity of MBT was revealed in children with low mass (to 19%) and in children with middle physiological parameters of body weight (0.4%). Long hypodinamics (more 60 days) was determined by decrease of (MBT)averagely to 21%from initial meanings whereas less reduction(to 30 days),lowering of physical movements and loads determined the decrease of MBT to 14%. It is necessary to mark that indices of MBT in children with orthopedic diseases of lower extremities were some higher (to 35%) than in children with orthopedic pathologies of upper extremities.

Thus, it is necessary to take into account that at conservative and long immobilization treatment BMT there are worsening risk factors such as osteopenia or osteoporosis in children.

The taken data show on necessity of taking medication among the children together with treatment of orthopedic pathology, improving mineral thickness of bone.
