FIELD: medical engineering. SUBSTANCE: device has supporting plates movably connected to distraction rods and fastening members fixed on the supporting plates, each manufactured as screw rod which fastening end has two parallel longitudinal planes and transverse opening. The device has acoustic emission gages connected to acoustic signal indication unit connected to computer communication unit and removable members mounted on fastening ends of the screw rods. An acoustic emission gage is to be mounted on one of the parallel planes of the screw rod end. The acoustic emission gage is fixed by means of quickly hardening glue of cyanacrylate group on fastening end of screw rod and removed by screwing off removable member mounted on fastening end of the screw rod. EFFECT: enhanced effectiveness in determining optimum forces to be applied when treating vertebral column deformities and injuries. 2 cl, 6 dwg
