摘要
Two cases of typeⅡodontoid fractures were reported to share our experience in surgery treatment of such cases.A 33-year-old woman with comminuted typeⅡodontoid fracture and a 42-year-old man with fracture end hardened typeⅡodontoid fracture received surgical treatment in our hospital.Though imaging examination suggested that these two patients were suitable for anterior screw fixation,we encountered difficulties during the operation.The two patients eventually underwent posterior C1–C2 fusion surgery and recovered well.According to the experience of these two cases,we found that the fracture line angle and the degree of comminution are two important factors affecting surgical decision-making.Although anterior screw fixation is the ideal choice for typeⅡodontoid fractures with anterior superior to posterior inferior fracture line,it may not be the best choice for comminuted or fracture end hardened typeⅡodontoid fractures.
