Abstract:
Objective To evaluate the diagnostic value of the C 2 “hypertrophic sign” in the axis fracture.Methods 37 cases with C 2 fracture confirmed by radiography,CT and operation partly retrospectively analysed,there were 29 men and 8 woman.After trauma all cases were examined by X-ray and 11 cases by CT scan.27 cases underwent operation.Results The incidence rate of the C 2 “hypertrophic sign” was 53.13%.This sign characterized by the distance increased between the anterior and posterior of the axis on the lateral conventional radiography compared with that of C 3 vertebrae.The maximal increasing distance was 11 mm and minimal one was 2.3 mm with average 4.3 mm.Fracture line and swollen soft tissue in front of the vertebra were showed in some cases.Conclusion The C 2 “hypertrophic sign” is main radiographic sign of C2 fracture.
