China News Service, Shanghai, February 21 (Chen Jing and Xi Xiaolei) Reporters learned on the 21st that with the assistance of the O-arm 3D navigation system, the orthopedic team of the Children's Hospital of Fudan University at the National Children's Medical Center treated a 3-year-old congenital spinal hemiplegia. Linlin (pseudonym), a child with vertebral body deformity, underwent surgery to accurately remove the hemivertebra and correct the scoliosis of the spine.

3-year-old Linlin suffers from congenital hemivertebral deformity of the spine. During a recent follow-up, the doctor discovered that the scoliosis was getting worse. In the Orthopedics Department of the Children's Hospital of Fudan University, the doctor found after examination that the child had the fifth thoracic hemivertebra, the ninth thoracic hemivertebra, and the first lumbar hemivertebra. The child had obvious scoliosis deformity. To improve the symptoms, surgical correction was the only option. .
According to the hospital, the nerves and blood vessels around the spine are rich, and doctors performing traditional surgical corrections are very likely to accidentally injure nerves, leading to general paralysis, or even inadvertently injure large blood vessels and cause massive bleeding. Wang Dahui, director of the Department of Orthopedics at the Children's Hospital of Fudan University, explained that the structure near the pedicles of the spine is complex, including the spinal cord, nerve roots, large blood vessels, etc., especially in patients with severe spinal deformities, which have developmental malformations, and the shape of the pedicles is different for everyone. If the surgeon is slightly biased, the pedicle screws may enter the spinal canal inward, which may easily cause spinal cord injury; if the pedicle screws may move outward, the orthopedic force may be reduced; and if the screws penetrate the anterior wall of the vertebral body, they may easily cause vascular damage. Therefore, traditional surgery for severe kyphotic deformity still presents significant risks and challenges. Therefore, the experts decided to use the advanced second-generation O-arm 3D navigation system to accurately remove the hemivertebral body and correct the scoliosis of the spine.
It is understood that navigation combined with O-arm technology is one of the most advanced orthopedic intelligent navigation and intraoperative three-dimensional imaging technologies in the world. Compared with traditional C-arm and G-arm, the advantages of O-arm are: it can complete multi-angle three-dimensional image scanning in 13 seconds, greatly reducing radiation dose; high-definition, complete, real-time three-dimensional image navigation can provide doctors with more information. Accurate nail positioning not only shortens the operation time, but also greatly reduces the probability of accidental nerve injury, thereby effectively reducing the occurrence of surgical complications. For patients, the surgery will be more accurate, efficient, safe, and minimally invasive, and the postoperative recovery time will be greatly shortened, achieving the goal of rapid recovery.
Before surgery, the O-arm 3D navigation system plans and simulates three-dimensional images to help the surgeon plan the best surgical path. During the operation, the patient can receive a complete 360-degree automatic ring scan, which can correct the doctor's deviations at any time to avoid damage to surrounding nerves, blood vessels, etc.
Wang Yi, president of the Children's Hospital of Fudan University, said that the National Children's Medical Center and the Children's Hospital of Fudan University will build an artificial intelligence design and precision bionic manufacturing center in the future. The O-arm 3D navigation system allows spine surgeons to have a wider surgical perspective, more accurately interpret spinal conditions, and accurately insert steel nails, greatly improving surgical safety. With the help of intelligent systems, doctors can perform more complex and difficult surgeries, making orthopedic surgeries minimally invasive, precise and intelligent. (over)
