摘要
Abstract
BACKGROUND: The cervical disc replacement requires standard operational procedure to reduce complications such as prosthetic subsidence, ectopic ossification or prosthetic dislocation. Individuated three-dimensional (3-D) reconstruction of cervical disc replacement can simulate structures of cervical disc, which is benefit for precise operation.OBJECTIVE: To study the method of computer assistant simulating the cervical disc replacement and clinic application.METHODS: A 42 years old male with C4-5 disc protrusion was selected. 64-row CT scan was performed before replacement,which was reconstructed using 3-D geometry. The interspace between 4/5, size of Cs upper endplate, and C4 low endplate was calculated. The interspace was enlarged and a prosthesis with appreciate size was choose. The cervical disc replacement was simulated by scanCAD software and the prosthetic size was modified, and then the procedure performed in operation.RESULTS AND CONCLUSION : It could reduce placement times effectively by simulating cervical disc replacement operation and design prosthetic sizes, which was convenient for operation and obtained good clinical curative effects. 3-D reconstruction simulating operation can measure the size of end plate and interspace of inter vertebra accuracy. The data were reliable and the operation could harvest satisfactory results.关键词
