The Application And Efficacy Of Direct Anterior One Screw Fixation In The Treatment Of Odontoid Fracture

Objective:To analyze the single-screw anterior fixation of odontoid fractures clinical efficacy, to explore a single-screw anterior fixation of odontoid fractures in the tre-atment of the applicat-Ion.Method:In December 2003～July 2007 in the DivisionⅠsingle-screw anterior f-ixation of the 15 cases of odontoid fracture typeⅡorⅢpatients with fractures and have done a retrospective analysis of follow-up.Intraoperative are right before the medial cervical incision,incision platysma and free soft tissue,external carotid sheath retractor,tracheoesophageal retractor inward, isolated anterior compartment,shown i-n front of vertebral body,lens positioning after anterior cervical 2 under end-plate screwed in the online guide pin,the location of the satisfaction,in the right direction un-der surveillance perspective screwed needle length corresponding single screw, brake neck circumference after 8-12 weeks,and follow-up cases of odontoid fracture healing.Results:The follow-up period was 8～50 months,with an average of 24 months.Preoperative pillow,neck pain,stiff neck symptoms,patients have been significantly improved,with three cases of patients with neurological symptoms of varying degrees of improvement.All patients satisfied with fracture reduction and fixation,with no incision infection,spinal cord and nerve injury, epidural complications such as rupture,all patients about 3 months after bone union had been without the formation of instability or pseudarthrosis without screw loose,spondylolisthesis,fracture.Conclusion:Conclusion of typeⅡorⅢpatients with odontoid fractures,single-screw anterior fixation,after which restored to the normal strength of 50%,neck activity restored to the normal 90%less injury,rehabilitation faster.It can also acti decrease the cervical collar fixed days; the patients could exercise on the floor in the early post-operative period;and elevation of the pationt'quality of life.Odontoid process is the treatment of typeⅡorⅢfracture of a rational and effective approach.But we should follow the clinical indications seriously People suitable for single-screw fixation in china.
