“…При этом у 5 из 38 добровольцев имело место функциональное укорочение одной из нижних конечностей в пределах 1 см, вызванное незначительным фронтальным перекосом таза и/или незначительным функциональным сколиозом при равенстве абсолютной длины нижних конечностей. Данный вариант функциональной асимметрии не является полностью физиологическим, однако ввиду своей высокой распространенности среди относительно здоровых лиц, слабого влияния на биомеханику ходьбы и отсутствия структурных аномалий, перманентно его обусловливающих, будет уместно пренебречь его наличием при настоящем и последующем формировании выборок [11,12].…”

Actuality. Gonarthrosis is one of the most insidious degenerative diseases, which has a number of gait biomechanical predictors. Of these, the most studied is the knee joint adduction moment in the support phase, however, there is a lack of research devoted to the search for its reference values among various age and gender groups. Purpose of research. Evaluation of gender and functional body asymmetry effect on peak moments of knee joint adduction in healthy volunteers. Materials and methods. The study was conducted on 38 healthy volunteers (17 men and 21 women) aged 20-45 years old through the motion capture hardware-software complex of the company "Vicon Motion Capture Systems". A comparative assessment was made for the first and second peaks amplitude of the knee joint adduction moment in the support phase. Symmetry was evaluated for both peaks in general, as well as separately for men and women. Gender differences for both peaks were evaluated in total for the right and left lower limbs. Results. The absence of significant intergroup differences in the both peaks amplitude of the knee joint adduction moment between the right and left legs, irrespective of gender (p0.05), was revealed, which demonstrates the symmetry of the adduction forces acting on the knee joint in the support phase. When comparing the both peaks amplitudes of the knee joint adduction moment in men and women, there was absence of significant differences for the first peak (p0.05), but a significantly higher second peak in males (p0.05). Conclusion. The obtained variability aspects of the peak moments of knee joint adduction will find their application in functional diagnostics using the motion capture technology.

Introduction. Restoration of trunk balance is the basic task in surgical correction of spinal deformities and in hip joint instability of various etiology. Purpose. To analyze and to define the relevance of roentgen-anatomical parameters of spine-pelvis relationships for surgical correction of deformities in the thoracolumbar spine and of hip joint instability of dysplastic and neurogenic etiology. Material and methods. An X-ray analysis of parameters of the frontal and sagittal spine-pelvis balance was performed in 220 patients with dysplastic and neurogenic deformities of the thoracic and lumbar spine (n = 98) and with instability of hip joints (n = 122) but who were able to walk. They were operated in the neuro-orthopedic department with orthopedics in National Medical Research Center for Children’s Health. The reference group included 60 relatively healthy children without any scoliotic deformities of the spine and with stable hip joints. Dynamics of changes in X-ray parameters was analyzed using findings of orthostatic spondylograms from the indicated groups of children. The obtained data were compared with reference values. Results. The trial performed has revealed typical changes in spine-pelvis relationship parameters in patients with hip joint instability and spine deformities and in the reference group . The researchers also found out relations between various parameters of the trunk balance before and after surgical correction. Conclusion. While planning a surgical correction of trunk balance in spinal deformities, one should take into account parameters of spine-pelvis relationships, such as PI, SS, PT, SVA deviation and the mid-sacral line; and in case of hip joint instability - local roentgen-angulometric parameters of the femoral and acetabular components of instability. This is due to the fact that the lower the level of reconstructive surgical manipulation is located, the greater effect it has at the frontal and sagittal balance of the trunk.
