Abstract:
AIM: To define the indications of C2 pedicle lag screw or C2 pedicle screw associated with C3 lateral mass screw to treat Hangman fracture, and evaluate the clinical applications. METHODS: Thirty-four patients with Hangman fracture were selected from Changzheng Hospital between February 2000 and December 2004, including 10 patients of type Ⅰ, 12 patients of type Ⅱ, and 8 patients of type Ⅱa, 4 patients of type Ⅲ. Levine-Edwards classification and graded: 2 patients of grade C spinal injury, 12 patients of grade Ds and 20 patients of grade E according to Frankel scale. Patients with typeⅠHangman's fracture were fixed by C2 pedicle lag screw, and patients with typeⅡ, Ⅱa and Ⅲ Hangman fracture were fixed by C2 pedicle screw associate C3 lateral mass screw. Postoperative neurofunctional recovery and fracture healing were studied. RESULTS: A total of 34 subjects were involved in the analysis of results. ① Frankle classification of postoperative neurofunctional recovery: There were 2 cases of grade C, 1 case recovered to grade E, and one case recovered to grade D. There were 12 cases of grade D, including 11 cases of recovered to grade E and one without change. ② In 3-6 months follow-up, X-ray of anterior-posterior and lateral position showed that all fractures healed without loose screw, vertebra artery injury or other complications. CONCLUSION: C2 pedicle lag-screw, C2 pedicle screw associated with C3 lateral mass screw are safe, effective in the treatment of Hangman fracture, which can to retain the function of upper cervical spine as great as possible.
