FIELD: medical engineering.
SUBSTANCE: device has rod having at least two fastening members for the fixing rods, the members being movably mounted on the rod and fixable in posterior positions; and removable compression-distraction device having casing and fastening member fixable on the rod and with pusher screw having hexagonal head at one end handled with wrench and thrust member pivotally connected to the screw at the other end and engageable to fixing rod tail in indirect way via a bar having longitudinal T-shaped slot on one side and guiding slot on the opposite side for receiving the fixing rod. The bar is arranged in parallel to the fixing rod and is movable along allowing distributing pressure over maximum available length of Schanz screw and avoid its deformation during distraction.
EFFECT: enhanced effectiveness of distraction and reduction of bone fragments.
