FIELD: medical engineering.
SUBSTANCE: device has proximal and distal ring-shaped support members connected to each other by means of threaded rods fixed in proximal ring-shaped support member. A pair of T-shaped threaded uprights is mounted on the distal ring-shaped support member in diametrically opposite points along one axis allowing axial displacements and fixation to take place. Cut bushings are movably and fixably mounted on smooth uprights cross-members. The bushings are connected to the rods and a pair of U-shaped uprights having threaded cross-bars are diametrically movably mounted along parallel axes and fixable on pedicles and bushings mounted on the uprights and fixable with nuts. The bushings are pivotally connected to the rods. Axes of all hinges are arranged on distal rod ends in parallel to each other in the same plane.
EFFECT: avoided bone deformities.
