Abstract:
[Objective]The purpose of this study was to determine the treatment odontoid fractures complicated by significant C2、3 displacement.[Method]Sixteen patients with odontoid fractures(12 type Ⅱ and 4 type Ⅲ,according to Anderson-D'Alonzo standard)were treated in this study.There were 11 male and 5 female with an average of 36 years(range 19-54 years).Group A included 9 cases of odontoid fracture with Hangman fracture and group B includcd 7 cases of odontoid fractures with C2、3 anterior fusion and 6 underwent dens screw with C2、3 posterior fusion.Postoperatively,neck collars were applied for 3 months.[Result]Successfully closed reduction of C1～2 was achieved in 16 patients.No complication occurred in the two groups.[Conclusion]Postoperatively there was no motion restriction in the neck or residual neck pain.Direct osteosynthesis of the fractured dens with screws is an effective procedure for unstable type Ⅱ fracture of the dens.Postoperative external immobilization with a neck collar seems to contribute much to the treatment.
