Through continuous exploration, PLA General Hospital has designed a new generation of minimally invasive adjustable growth valve with independent intellectual property rights to treat severe idiopathic scoliosis deformities in children and achieved good results. At the Chinese Society of Orthopedic Societies Spinal Surgery Advanced Training Course and the Second China Scoliosis International Symposium on May 21, this technology received wide attention and praise from more than 500 participating experts and scholars. Growth valve technology is mainly used in children with scoliosis deformity, including the existence of potential growth of congenital scoliosis, idiopathic scoliosis. Due to the low maturity of children, the spine, especially the growth potential of the anterior column larger, if the one-time final orthopedic fusion surgery, on the one hand the growth of children's torso will inevitably have some impact, on the other hand the early development of vertebral body stagnation Will also affect the development of spinal canal structure, has a potential impact on children's neurological development. Growth valve technology first appeared in the 1990s, mainly in the laminectomy structure, with the development of thoracic pedicle screw technology, internal fixation devices improved, the current main structure are nail-hook structure or all-nail structure. People's Liberation Army General Hospital orthopedic minimally invasive adjustable growth valve main features are: high safety, one side of the serrated extension of the spur structure pitch is small, the stress is uniform during the extension, due to local anesthesia can be done under a small incision , So you can shorten the extension of the pitch time, truly a small number of times. Good adjustability, serrated bite structure can be measured by adjusting the screwdriver handle torque device from the device during the orthopedic extension of the stress. Minimally invasive, local anesthesia 1 cm incision to complete the operation, even with the younger children with basic anesthesia is also very convenient.
