Posterior laminoplasty combined with foraminotomy in treatment of mixed cervical spondylosis / 局解手术学杂志

ABSTRACT

Objective To study the clinical efficacy and safety of posterior laminoplasty combined with foraminotomy in the treatment of mixed cervical spondylosis.Methods A total of 70 patients with mixed type cervical spondylosis from January 2012 to January 2014 in our hospital were randomly divided into observation group and control group.Patients in observation group received posterior laminoplasty com-bined with foraminotomy,and patients in control group received anterior cervical discectomy and fusion surgery.The operation time,intraoper-ative blood lossing,postoperative JOA scores and NDI scores between two groups were compared.The cervical curvature and range of motion were measured by X-ray.Results There was no significant difference in postoperative JOA scores,cervical curvature and range of motion be-tween two groups(P >0.05).The operative time and intraoperative blood loss of observation group was less than those of control group,the difference was no significance.The NDI scores of carrying and drive in observation group were higher than those in control group,while the NDI scores of other items between two groups had no significant difference(P >0.05).The incidence of complications in observation group was 10.81% (4 /37),the control group was 24.42% (8 /33),the difference between two groups was statistically significant,(χ2 =3.428, P <0.05).Conclusion The posterior laminoplasty combined with foraminotomy have good clinical effect for mixed type cervical spondylosis with advantages of a shorter operation time,simple operation,less intraoperative bleeding,lower incidence of complications,which is a kind of safe and effective surgical method.
