Abstract：Objective To investigate the clinical effectiveness of one-stage anteroposterior approach in trea-ting lower cervical fracture dislocation and articular process interlocking .Methods From Sep.2008 to May 2012,32 adult patients with cervical fracture dislocation and articular process interlocking were enrolled in this study (23 pa-tients with unilateral facet dislocation ,9 patients with bilateral facet dislocation ) .The ASIA grading system for pre-operative neurological function indicated that there were 5 cases of grade A ,12 cases of grade B ,11 cases of grade C , 3 cases of grade D ,and 1 case of grade E . All the patients were treated with reduction and fixation through an anteri-or and posterior method .The segmental stability and bone graft fusion were evaluated through the postoperative radio -graphic examinations , the neurological status was reviewed preoperatively and postoperatively . Results All cases were followed up for a mean time of 15 months(10-24 months).The results of decompression and reduction were sat-isfactory,the intervertebral height and lordosis were maintained normal ,bone fusion was achieved ,and no plate and screw related complications were observed .Grade 1-neurological recovery was achieved in 29 cases and no neurologi-cal recovery was obtained in the other 3 cases of grade A .Conclusion One-stage anteroposterior approach has a sat-isfactory clinical effect in treating lower cervical fracture dislocation and articular process interlocking .
