The CHARSPINE2 VD set of vertebral body derotation instruments, designed by the team of ChM specialists, has been developed to meet the challenges surgeons face when treating complex spine deformities (scoliosis) and to broaden the application of recognized and clinically proven CHARSPINE2 bar stabilization system. CHARSPINE2 VD utilizes the direct vertebral derotation technique that enables three-dimensional correction of spinal disorders. The system consists of sleeves and clamps that can be combined into convenient blocks ensuring the most effective correction of deformity. The CHARSPINE2 VD instrument set has been espe- cially designed for and is fully compatible with CHARSPINE2 bar stabilization system. Posterior surgical approach to the thoracolumbar spine and instructions for transpedicular screws insertion have been described in a separate surgical technique No. ST/96 for CHARSPINE2 thoracolumbar spine stabilization system. The selection of appropriate screws is a key factor to ensure the success of the spine derotation procedure. Monoaxial screws guarantee the highest stability, however, due to possible difficulties with rod fitting, polyaxial or uniplanar screws may be required. For scoliosis correction, the use of reduction screws should be considered since the screws significantly facilitate the bar placement. The transpedicular screws should be inserted at each level of the concave site of the scoliosis, whereas on the convex side - the screws should be inserted at both ends of the scoliosis arch and at its apex.
