Description

The CHARSPINE2 VD set of vertebral body derotation instrumentation, designed by the team of ChM specialists, has been developed to meet the challenges sur-geons face in the treatment of complex deformations and to broaden the application of known and clinically proven CHARSPINE2 bar stabilization system.The new system provides solutions to surgeons when treating spinal deformities (scoliosis). CHARSPINE2 VD utilizes the direct vertebral derotation technique that allows for three-dimensional correction of spinal disorders.The system consists of sleeves and clamps that can be combined into blocks in any way ensuring the most effec-tive correction of deformity.The CHARSPINE2 VD instrument set has been especially designed for and is fully compatible with CHARSPINE2 bar stabilization system. Surgical posterior approach to the thoracolumbar spine and instructions for tran-spedicular screws insertion have been described in a separate surgical technique No. ST/63 for CHARSPINE2 thoracolumbar stabilization system. The selection of appropriate screws is a key factor to ensure the success of the dero-tation procedure. Monoaxial screws guarantee the highest stability, however, due to possible difficulties with fitting the rod, polyaxial or uniplanar screws may be required. For scoliosis correction, the use of reduction screws should be consid-ered 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.
