Objective To compare the effectiveness between anterior cervical Zero-profile interbody fusion device (Zero-P) and anterior cervical plate device (plate cage benezech, PCB) for cervical disease. Methods Between February 2011 and January 2013, 98 patients with cervical spondylosis who accorded with the inclusion criteria were treated with Zero-P in 49 cases (group A) and with PCB in 49 cases (group B). There was no significant difference in gender, age, disease type, disease duration, and disease segments between 2 groups (P>0.05). The Cobb angle, short-form 36 health survey scale (SF-36 scale), Japanese Orthopedic Association (JOA) score, postoperative dysphagia cases, neck disability index (NDI), and visual analogue scale (VAS) score were compared between 2 groups. Results The operation time and intraoperative blood loss of group A were significantly less than those of group B (t=4.089, P=0.000;t=3.587, P=0.001). The patients were followed up 3-36 months (mean, 18.5 months). No loosening or breaking of internal fixation and bone absorption or collapse occurred in the other patients except 2 patients who suffered from screw loosening at 3 months after operation. Within 6 months after operation, dysphagia occurred in 8 cases (16.33%) of group A and in 13 cases (26.53%) of group B, showing significant difference (χ²=10.616, P=0.001). At last follow-up, JOA score, VAS score, NDI, SF-36 scale, and Cobb angle were significantly improved when compared with preoperative ones in 2 groups (P<0.05);the other indexes of group A were significantly better than those of group B (P<0.05) except SF-36 scale and Cobb angle (P>0.05). The excellent and good rate of JOA score was 81.63% in group A and 71.43% in group B, showing significant difference (χ²=4.346, P=0.037). Conclusion Zero-P and PCB can get good results in treatment of cervical disease, but the Zero-P is better than PCB in reducing postoperative dysphagia because less wounds and strong stability.
