Analysis of anterior cervical discectomy or corpectomy with fusion for treatment of 2-level cervical spondylosis accompanied by sympathetic symptoms

Objective To investigate clinical and radiologic results of anterior cervical discectomy with fusion(ACDF) and anterior cervical corpectomy with fusion(ACCF) in treatment of 2-level cervical spondylosis accompanied by sympathetic symptoms.Methods A total of 48 patients who underwent ACDF(n=26) or ACCF(n=22) for cervical spondylosis accompanied by sympathetic symptoms were eligible for this study in Jan.2001 through Aug.2011.The clinical and radiologic data of these 48 patients were retrospectively analyzed and compared between the two groups.Results All patients were followed up for 15 ~58 months.No significant difference was detected between the two groups on postoperative hospital stay,postoperative amelioration of JOA scores and sympathetic symptom scores,fusion rate and complication(P 0.05).The operative time,blood loss,the height loss of fused segment and the Cobb's angle loss of fused segment were significantly greater in ACCF group(P 0.05).Conclusion ACDF and ACCF both obtained favorable clinical outcomes in treating 2-level cervical spondylosis accompanied by sympathetic symptoms.However,ACDF is superior over ACCF in terms of operation time and bleeding amount,segmental height and segmental Cobb's angle.
