recently,According to Mohou.comsuccessfully applied by the Department of Spine Surgery of the Affiliated Hospital of Weifang Medical College3DPrinting technology completed a difficult spinal operation – atlanto-axial internal fixation and fusion surgery. In spine surgery, this operation is an upper cervical spine and high-risk operation that many doctors do not dare to “touch” easily. The surgical site is dangerous and complex. A slight deviation in screw placement during surgery may injure the medulla oblongata and. the vertebral artery and endanger life. The whole operation, like dancing on the tip of a knife.
The patient is52A 20-year-old woman presented to the Spine Surgery Department of Affiliated Wei Medical Hospital due to unsteady walking and limb numbness. Based on the patient’s condition, chief physician Teng Haijun and deputy chief physician Zhao Sishun carefully examined and accurately diagnosed rheumatoid arthritis and atlantoaxial dislocation. Based on the treatment principle of “individualized, minimally invasive and precise,” it was decided to perform atlantoaxial fixation. and fusion surgery for the patient. Due to the special anatomical structure of atlantoaxial spine surgery, the vertebral body is small. If the screw placement is slightly deviated during surgery, the vertebral artery and medulla oblongata may be damaged and the surgical risk is very high.
Additionally, this patient has suffered from rheumatoid arthritis for over 30 years and long-term use of hormones has led to osteoporosis. If the nail cannot be successfully placed in one go, the holding force will be reduced and the operation will fail. Although doctors can rely on their rich experience to perform nail placement, in order to increase safety, the preoperative spine surgery team uses3DUsing printing technology, a model of the patient’s cervical spine was printed and detailed preoperative planning was developed based on discussions, attempts and repeated exercises on the model. At the same time, in order to control rheumatoid, patients are scheduled in advance for a period of anti-rheumatoid treatment in the rheumatology and immunology department to complete preoperative preparations. The operation was performed by Deputy Chief Physician Zhao Sishun and Chief Physician Wang Sheng, who worked together to successfully insert the screws in one go and successfully completed the operation. The patient’s symptoms improved significantly after the operation. Currently, the patient has been cured and discharged from the hospital and is very satisfied with the results of the operation.
In recent years,3DPrinting technology has been widely used in clinical practice. In addition to printing patient spine models to simulate surgical planning, it can also be used in many aspects such as navigation modules for osteotomies and personalized anatomical prostheses, bringing a revolutionary advancement in safety surgical. and also provide protection for more complex and dangerous surgical procedures in the future. Department of Spine Surgery, Affiliated Hospital of Wei Medical3DLeveraging printing technology, more precise, individualized and minimally invasive “targeted” surgeries are implemented, with remarkable therapeutic effects and continuous improvement in patient satisfaction.
