CLINICAL AND RADIOLOGICAL FEATURES OF THE LOWER EXTREMITIES IN CHILDREN WITH OSTEOGENESIS IMPERFECTA
Osteogenesis imperfect is a group of hereditary diseases characterized by osteoporosis, bowing of the bones of the axial skeleton and limbs. Osteogenesis imperfecta has various types of inheritance, varying degrees of severity of clinical manifestations. Clinical manifestations are significantly dependent on previous treatment. This article presents results of research of the anatomical and functional condition of the bones of the lower extremities. The main attention is paid to deformities of the shaft, since it is they that have the greatest impact on the function of the limbs and determine the risk of pathological fractures, and hence the severity of the disease. It was revealed that the most characteristic deformations were varus, antecurvation deformity of the femur, valgus and antecurvation deformation of the tibia, flat-feet. Normal hip joints were prevailed. Hip deviations were coxa vara including with the pseudoarthrosis of the neck or trochanteric part. There have also been cases of protrusion of the acetabulum, retroversion of the neck. There was a dependence of the severity of changes in the bones in the shaft on the type of osteogenesis imperfecta, the severity of the manifestations of the disease and age. In the first in most cases was the bowing of the femur. The development of deformities of the tibias occurred later.
