Abstract:
Objective To compare the clinical outcomes of Bryan disc replacement with anterior cervical discectomy and fusion (ACDF) in patients with cervical spondylopathy. Methods Sixteen patients underwent Bryan cervical disc replacement (A group), and 35 patients underwent traditional ACDF (B group) were included in the study. Patients were followed up at regular intervals. The JOA score, SF-36, neck disability index (NDI) score and the dynamic flexion-extension radiographs were used to evaluated the oucomes.Results All the patients were followed up for more than 6 years (mean, 73.5 months). There were no severe adverse events in both groups. In A group, there were no differences between postoperative and preoperative mobility of surgical segments (P＞0.05). All patients obtained bone fusions 6 month after surgery in group B.In both groups, the clinical symptoms relieved obviously after surgery. The postoperative scores of the JOA,SF-36 and NDI significantly improved compared with those of preoperative ones (P＜0.05). In B group, range of motion (ROM) was significantly decreased postoperatively (P ＜0.01); in A group, there were no significant differences between postoperative and preoperative ROM (P＞0.05). The difference between two groups regarding ROM was noted (P＜0.05). Conclusion The mid-term outcomes of Bryan cervical arthroplasty are satisfied. And the cervical arthroplasty which can maintain the mobility of the segment, and decrease the incidence of the postoperative neck axial symptoms is a viable alternative to cervical spondylopathy.
