1. Dyflex-III fixation system(D-III hereafter) developed by Tae Yeon Medical Co., Ltd has made a significant difference with the ordinary pedicle screw systems, the screw-head movement of D-III made not only easy operation of surgeons but also patient to feel a lot comfortable after surgery. Moreover D-III flexible rod has mobility which ordinary rod doesn’t have, it does even make great improvement of patient’s comfort and satisfaction.
2. In case of patients who had spine-fusion with ordinary pedicle screw, nonunion cases are reported as 5~7% of degenerative lumbar spinal stenosis and 25~35% of degenerative spinal canal stenosis due to too much stiffness on spinal segments.
Moreover breakage of the implants and acceleration of degenerative symptoms on the segments which had spinal-fusion with pedicle screws are well known major weak points of spinal fixation system.
Ligament reconstruction by dynamic stabilization system provides not only stabilization on fusion site, but also preserves physiological function of spine.
It significantly preserves the regular spine movement and had many advantages such as great safety, less operation time, and fast recovering.
However for the best performance, dynamic stabilization system should be operated at the beginning stage of degenerative spinal stenosis.
3. Dyflex-III fixation system developed by Tae Yeon Medical has advantages of both ordinary fixation system and dynamic stabilization system.
In other words, by having immobilization of ordinary fixation system and movement of dynamic stabilization system, D-III supplemented weak points of both systems.
Not only for the movements and comforts which can be satisfied by D-III, it also provides great safety and acceleration of spine-fusion by this micro-motion that transfers stress and load on fixation system.
4. D-III fixation system is compatible with other pedicle screw products of Tae Yeon Medical Co., Ltd. However in this case, the 100% performance can’t be made as it is designed for.
Therefore it is highly recommended to use only D-III system for the best performance and satisfaction.
Dyflex-m spinal system was evaluated by not only mechanical test but also simulation in virtual clinical conditions for preserving patients safety. X-RAY of spinal system was to forecast weak points and to find optimal stress conditions with Finite Element Method. Spinal system was mechanically tested in various conditions, such as compression, tension, torsion and fatigue.
The new system, composed of flexible rods and dynamic screws, absorbs the impact or load through the rods and the screws respectively, and allows excellent safety and effective perfomance compared with conventional systems which may result in subsequent fracture on the bones adjacent to the bone implanted the conventional systems due to the stress occurred.
Dyflex-ID Flexible Rod
The product is designed to have triple structure in the flexible region.
Therefore, it is excellent in flexibility to minimize the impact or load on the bones, being absorbed by the unique triple structure.
Dyflex-ID is new generation product of spinal system bydynamic screw with flexible Rod.
Dyflex-ID will show you little motion after the surgical operation. It will give marvelous satisfaction to patient and to the surgeons.
