Abstract:Objective To evaluate the methods and efficacy of operative treatment of cervical hyperextensioninjury.Methods 83 cases of cervical hyperextension injury were retrospectively analyzed from January 2012 to June 2015.There were 63 males and 20 females,aged 25~78 years,average 58.5 years old.All patients were accompanied by spinal cord nerve lesions.According to Frankel classification,grade A accounted for 4 cases,grade B accounted for 18 cases,grade C accounted for 32 cases and grade D accounted for 29 cases.All patients underwent surgical treatment.72 cases were treated with anterior disectomy or corpectomy,bone grafting andplate fixation.11 cases weretreated with posterior decompression with laminoplasty andlateral mass screws or pedicle screws fixation.Results All of them were followed-up for 9 to 18 months.All bone grafts fused,no failure of internal fixations was found.Preoperative and postoperative Frankel classifications and ASIA(American Spinal Injury Association)grades were compared between the two groups.The neural function improved significantly between the two groups after operation.The average of Frankel class increased by 1~2 grade.ASIA score increased by (26.2±5.4) among anterior group(P=0.019),and increased by (15.2±6.1) in the posterior group(P=0.036).Cases underwentanterior approach had significantly better result in neural function than the posterior approach group(P<0.05).Conclusion It’s preferred to choose anterior decompression with bone grafting and internal fixation as the surgical choice to treat cervical hyperextensioninjury.The posterior surgery also result in an effective outcome,which could be a supplement to the anterior surgery.
