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 C5 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 endplate and interspace of inter vertebra accuracy. The data were reliable and the operation could harvest satisfactory results.
