Recently, Professor Dean of Guangzhou Military General Hospital orthopedic hospital YIN Qing-shui, said: "Digital orthopedics is a new technology of digital computer technology closely integrated with the orthopedic clinic, through this technology, we can rely solely on the complexity of the previous orthopedic surgeon experience surgical accurate to 1-2 mm, surgical success rate improved from 60% to 90% before. "
It is understood that one year ago, the orthopedic hospital successfully performed atlantoaxial anterior and posterior internal fixation for a patient who was only two years old due to a dislocation of the atlantoaxial (upper cervical vertebrae) due to a car accident and caused spinal cord compression. High-risk, difficult surgery has not been reported internationally.
Digital orthopedics is actually a comprehensive new technology based on orthopedics, computer image technology to assist multi-disciplinary design, including medical image processing, three-dimensional virtual simulation and visualization technology, clinical CAD/CDM technology, intraoperative Surgical navigation and robotic assistive technology.
Dean Yin Qingshui said that digital orthopaedic technology is currently mainly used for orthopaedic surgery with high difficulty and complexity. Before the operation, the experts first used advanced CT and other techniques to scan the patient or the wound site for comprehensive data, and then use the data to build a three-dimensional image of the virtual bones accurate to the millimeter level on the computer. Through three-dimensional imaging, experts can clearly observe The condition of each detail of the affected area greatly enhances the cognition of the patient's condition, and the expert can perform simulated operation on the computer software.
“After establishing the three-dimensional image, we can use the instrument to create a three-dimensional solid model with a ratio of 1:1.†Dr. Wan Lei of the Orthopaedic Hospital said that the raw material of this solid model is polyester vinyl powder, which is solidified by laser sintering. A three-dimensional object is printed and printed as a specimen, and the expert can then discuss the case according to the specimen.
Experts will perform repeated simulation exercises on how to position the card, determine the position of the screw, and how to stabilize before the operation to ensure the safety and one-time success. And this solid model can be brought into the operating room through high-temperature disinfection. During the operation, the doctor can observe the model to understand the overall situation of the diseased part of the patient, thus ensuring the accuracy of the operation.
Before the application of digital orthopedics technology to orthopedic clinical treatment, orthopedic surgery generally relies on the experience of the surgeon. Because personal estimates and actual conditions are not willing to achieve 100% uniformity, there is often a deviation of the angle of the nail implant and the orthopedic position. Accurate and other conditions, after the introduction of digital orthopedics, many unmeasurable data can be accurately measured by computer. Preoperative computer aid can be used to design individualized surgery, simulate surgery, so that complex fractures can be surgically restored, and tumors can be accurately removed. The deformity can be ideally corrected and the prosthesis can be accurately implanted. It is the tradition of previous clinical surgery that emphasizes experience and feel. During the operation, computer-assisted individualization techniques can also accurately locate nails and orthotics, minimizing the possibility of complications.
