Background
Stiff spine deformities are common clinically, and treatment of stiff spine deformities is mainly through osteotomy orthopedic surgery, and often requires three-column osteotomy to correct stiff deformities. Although osteotomy orthopedic techniques are well established and widely used clinically, the "dislocation of the osteotomy end" is still considered by the majority of spinal surgeons as one of the most serious complications of osteotomy, closely related to severe spinal cord or cauda equina injuries.
The most important way for preventing the dislocation of the osteotomy end in the past is the tight cooperation and careful operation of an operator and an assistant, the osteotomy closed reduction is slowly carried out by simultaneously pressing down the orthopedic rods from the head side to the tail side, or the aim of avoiding the dislocation of the osteotomy end is achieved by pre-placing an intervertebral fusion device (cage). However, because the two ends of the three-column osteotomy are completely separated or only one cortical bone layer at the front edge of the vertebral body is connected, and the trunk weight at the head end and the tail end is larger, the closing process can cause dislocation of the osteotomy end even irreversible injury to the spinal cord and nerves, thereby causing serious clinical consequences. In addition, placing an intervertebral cage (cage) can add significant surgical expense.
