Three-dimensional correction, application flexibility and implant rigidity.
DePuy Spine's Kaneda Anterior Scoliosis System (KASS) is a two-rod, multi-segmental instrumentation system that provides both flexibility of the implant for application to the deformed spine, overall rigidity to correct spinal deformities, and the ability to maintain structural support of disc spaces to avoid "settling" during graft incorporation. The fundamental advantage provided by the KASS system is the ability to obtain a very high degree of correction of thoracolumbar and lumbar scoliosis along with derotation and restoration of physiologic sagittal plane alignment.
The KASS system provides spine surgeons an anterior means to correct scoliosis by attaching two vertebral screws and a vertebral staple to each vertebral body in the curve, and using two rods to provide superior three-dimensional correction when correcting the deformity. All implants are designed to accommodate a surgical approach from either side of the patient.
