Intelligent navigation+3D imaging technology to assist in minimally invasive and precise orthopedic surgery
2024-02-22
On the 21st, it was learned that with the assistance of the O-arm 3D navigation system, the orthopedic team of the Fudan University Affiliated Pediatric Hospital of the National Children's Medical Center performed surgery on a 3-year-old child with congenital spinal hemivertebral deformity named Lin Lin (pseudonym), accurately removing the hemivertebral body and correcting the scoliosis of the spine. 3-year-old Linlin suffers from congenital hemivertebral deformity of the spine. During recent follow-up, doctors have found that scoliosis is progressively worsening. At the Department of Orthopedics at the Affiliated Pediatric Hospital of Fudan University, doctors found through examination that the child had significant scoliosis deformities in the 5th thoracic vertebra, 9th thoracic vertebra, and 1st lumbar vertebra. To improve the symptoms, surgical correction is necessary. According to the hospital, there are abundant nerves and blood vessels around the spine. Traditional surgical correction by doctors is highly likely to cause accidental nerve injury, leading to systemic paralysis, and even accidental damage to large blood vessels, resulting in massive bleeding. Wang Dahui, Director of the Orthopedics Department of the Affiliated Pediatric Hospital of Fudan University, explained that the structure near the spinal pedicle is complex, including the spinal cord, nerve roots, and large blood vessels. Especially for patients with severe spinal deformities, they have developmental abnormalities themselves. In addition, each person's pedicle shape is different. If the chief surgeon has a slight deviation, the pedicle screw entering the spinal canal inward can easily cause spinal cord injury, and if the pedicle screw is outward, it can easily reduce the corrective force Screw penetration through the anterior wall of the vertebral body can easily cause vascular damage. Therefore, traditional surgery for severe scoliosis still poses great risks and challenges. So, experts decided to use the advanced second-generation O-arm 3D navigation system to accurately remove half of Lin Lin's vertebral body and correct her scoliosis of the spine. It is understood that navigation combined with O-arm technology is currently one of the most advanced orthopedic intelligent navigation and intraoperative 3D imaging technologies in the world. Compared to traditional C-shaped and G-shaped arms, the advantage of an O-shaped arm is that it can complete multi angle 3D image scanning in 13 seconds, significantly reducing radiation dose; High definition, complete, and real-time 3D image navigation can provide doctors with more accurate nail positioning, significantly reducing the probability of nerve injury while shortening surgical time, thereby effectively reducing the occurrence of surgical complications. For patients, surgery will be more precise, efficient, safe, and minimally invasive, and the postoperative recovery time will be significantly reduced, achieving the goal of rapid recovery. Before surgery, the O-arm 3D navigation system plans and simulates three-dimensional images to plan the optimal surgical path for the chief surgeon. During surgery, patients can receive a complete 360 degree automatic circular scanning image, which can be corrected by the doctor at any time to avoid damaging surrounding nerves, blood vessels, etc. Wang Yi, Dean of Fudan University Affiliated Pediatric Hospital, stated that the National Children's Medical Center Fudan University Affiliated Pediatric Hospital will build an artificial intelligence design and precision biomimetic manufacturing center in the future. The O-arm 3D navigation system allows spinal surgeons to have a wider surgical perspective, more accurate interpretation of spinal conditions, and more accurate placement of steel screws, 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. (Lai Xin She)
