Anterior decompression and interbody fusion with plate fixation for cervical spondylosis myelopathy

目的 :分析颈前路减压钢板内固定术治疗脊髓型颈椎病的临床疗效。方法 :对 10 3例脊髓型颈椎病患者行颈前路减压植骨钢板内固定术 ,并对临床结果进行Odom′s法疗效评定及影像学分析。结果 :10 3例中获随访 99例 ,临床疗效优良率 80 % ,植骨融合率为 97 9% ( 97/ 99) ,其中单节段椎间融合率为 10 0 % ( 12 / 12 ) ,多节段椎间融合率为 97 7% ( 85 / 87)。结论 :颈前路钢板内固定对于脊髓型颈椎病的治疗是有益的 ,提高了植骨融合率 。

objective:To analyze the clinical and radiological outcomes of anterior decompression and interbody fusion with an additional plate fixation for cervical spondylosis myelopathy.Method:One hundred and three patients with cervical spondylosis myelopathy treated by cervical anterior decompression,interbody fusion,and plating were analysed retrospectively.The outcomes was assessed by clinical criteria and radiographs of the cervical spine.Result:Ninetynine patients were followed up for twelve months in average.The rate of excellent and good results was 80%. The overall fusion rate was 979%.A solid fusion was obtained in all cases with a singlelevel fusion and in 977 % of the cases with a multilevel fusion.Conclusion:This study demonstrated that plate fixation can reduce the rate of nonunion and increase the rate of fusion in patients undergoing interbody fusion for cervical spondolysis. The clinical results appear promising. Author′s address Department of Orthopedics,Changzheng Hospital,Second Military Medical University,Shanghai,200003
