颈前路空心加压螺钉治疗Ⅱ型齿状突骨折

Anterior fixation for type Ⅱ odontoid fractures with compressive cannulated screw

目的探讨前路单枚空心加压螺钉内固定治疗Ⅱ型齿状突骨折的临床疗效。方法 C臂X线机透视下采用前路单枚空心加压螺钉内固定治疗AndersonⅡ型齿状突骨折24例。结果 24例均获随访,时间12-48（24±12）个月。患者全部骨性愈合。无术中及术后并发症。末次随访时无内固定螺钉松动、移位或断裂,颈椎活动无明显受限。结论前路空心加压螺钉固定治疗齿突骨折既可提供良好的稳定性,又能保留寰枢关节活动性,骨折愈合率较高,并发症低,是治疗Ⅱ型齿突骨折有效的方法。

Objective To investigate the curative effect of anterior fixation for type Ⅱ odontoid fractures with compressive cannulated screw.Methods 24 patients presented with acute traumatic type Ⅱodontoid fractures were treated by anterior odontoid compressive cannulated screw fixation with help of C-arm X-ray machine.Results All the cases were followed up range from 12 to 48 months with an average of（24±12） months.Radiographic bone fusion were got in all patients.No complications related to the surgical approach or hardware failure were identified and no signifirant limitation of cervical motion was found at lost followup.Conclusions Anterior fixation with compressive cannulated screw for type Ⅱodontoid fractures is associated with a relatively low complication rate and a high fusion rate in this study,offering stable fixation and reserving all normal cervical motion.It is an effective treatment method for acute typeⅡodontoid fractures.
