A few days ago, the Department of Orthopedic Surgery of Wuhan Union Medical College Hospital successfully implemented the “hunchback” correction surgery for 18-year-old girl Xiao He. After the operation, Xiao He, who recovered well, looked very happy and confident, as her height increased, she became more erect. Two years ago, Xiao He’s mother inadvertently found that her daughter’s shoulders are not equal, the body to one side of the skewed, the back is also obviously protruding, the formation of a “hunchback”. It was not until recently that her mother took Xiao He to the Department of Orthopedic Surgery of Union Hospital for treatment. During the examination, the doctor found that Xiao He’s scoliosis had exceeded 70 degrees, and the whole spine was obviously “S”, so he had to be hospitalized for surgical correction. Yang Cao, Associate Professor of Orthopaedics at Wuhan Peking Union Medical College Hospital, performed the most advanced thoracic pedicle screw and parietal de-rotation spinal orthopaedic surgery for Xiao He two weeks ago, using two titanium rods and more than ten titanium nails to form an internal fixation system to give the surgical orthopaedic treatment, and the nails were successfully inserted at one time. After the surgery, Xiao He’s spinal deformity improved significantly, his appearance was not much different from that of a normal person, and his height increased by nearly 4 centimeters, which showed that the de-rotation orthopedic technology played an important role in the surgical treatment of scoliosis patients. According to Yang Cao, scoliosis is a kind of spinal deformity that occurs in adolescents during growth and development. This deformity is not simply bending to one side, but occurs and develops in three-dimensional space, and axial rotation of the vertebrae is one of the basic deformities of scoliosis. All scoliosis has varying degrees of axial rotation, and the greater the angle of rotation, the more pronounced the appearance of the deformity, which can lead to the occurrence of deformities such as razorback deformity, thoracic deformity, and in severe cases, may even affect cardiorespiratory function. “Traditional scoliosis surgery only emphasizes coronal and sagittal plane orthopedics, and the previous ‘rotating rod technique’ is not really a de-rotated three-dimensional orthopedics.” Yang Cao said that the orthopedic department of Xiehe Hospital’s orthopedic surgery for Xiaoho used thoracic pedicle screw technology and parietal de-rotation technology, which are the most advanced surgical techniques in the field of three-dimensional orthopedics for scoliosis. Since the de-rotation of the parietal vertebra requires the placement of the nail in the concave side of the parietal vertebra, and the arch of the parietal vertebra is very thin and often accompanied by developmental deformities, the slightest deviation of each nail from the “track” may cause spinal cord neurological damage or even paraplegia of the patient, therefore, the precise implantation of the pedicle screws requires a very high level of technical accuracy.
