The growth valve technique is a brand new technique for the treatment of pediatric scoliosis, which is actually a non-fusion surgery, mainly applied to children under 10 years of age with scoliosis deformity, including congenital scoliosis and idiopathic scoliosis with potential growth potential. Due to the small size of the child, the growth potential of the spine, especially the anterior column, is large. If a one-time orthopedic fusion surgery is performed, on the one hand, the length of the child’s torso will inevitably be affected to a certain extent, with an average reduction in the height of each vertebral segment of about 5 mm, which can lead to a short torso and an imbalance in the ratio of torso/height; on the other hand, an early stagnation of vertebral development will also affect the development of vertebral canal structures, with a certain potential neurological impact. The growth valve technique requires incision and extension every 6-12 months. Typical case: Female, 4 years old, congenital lateral kyphosis, coronal Cobb angle 60°, sagittal thoracic kyphosis Cobb angle 70°, three-dimensional CT reconstruction showed congenital spinal deformity, the height of the child was 92cm, the child was treated with the growth valve double-rod internal fixation technique, and the orthopedics was satisfactory, with a coronal Cobb angle of 16°, sagittal thoracic kyphosis Cobb angle of 25°, and the height increased to 95cm. At the 6-month follow-up, the child’s scoliosis was aggravated (coronal Cobb angle of 40°, sagittal thoracic kyphosis of 30°), and his height increased to 98 cm, so he underwent bracing surgery, and his height was 99 cm, and his scoliosis was further corrected (coronal Cobb angle of 12°, sagittal thoracic kyphosis of 24°). At the postoperative review in December, the child’s scoliosis was aggravated again (coronal Cobb angle 28°, sagittal thoracic kyphosis Cobb angle 30°), and his height increased to 101 cm, so he underwent a second bracing operation, and after the operation, his height was 99 cm, and his scoliosis was further corrected, and his orthopedic effect was satisfactory (coronal Cobb angle 9°, sagittal thoracic kyphosis Cobb angle 35°), and he increased to 102.5 cm in height. The height was increased to 102.5 cm.
