- Abstract
Objective: To investigate the effect of Bryan cervical disc prosthesis replacement on the curative effect and the biomechanics of the cervical spine in patients with cervical spondylotic myelopathy. Methods: 48 patients with cervical spondylotic myelopathy who were treated in our hospital from January 2015 to December 2016 were selected. According to the different operation methods, they were divided into bone graft fusion group(25 cases) and prosthetic replacement group(23 cases). The bone graft fusion group was treated with anterior cervical decompression and fusion, the prosthesis replacement group was treated with Bryan cervical disc prosthesis replacement. The scores of Japanese Association for Department of orthopedics(JOA), neck disability index(NDI), visual analogue scale(VAS), cervical physiological curvature, cervical spine activity, surgical segment activity, upper adjacent segment activity,lower adjacent segment activity were compared between the two groups, and the complications of the two groups were compared.Results: The NDI score in the prosthetic replacement group at 12 month after operation was significantly lower than that of the bone graft fusion group(P<0.05). The cervical spine activity in the bone graft fusion group at 6 months, 12 months after operation were lower than those of the prosthetic replacement group(P <0.05). The surgical segment activity in the prosthetic replacement group at 1 month, 3 months, 6 months, 12 months after operation were significantly higher than those of the bone graft fusion group(P<0.05). The upper and lower adjacent segment activity in the the bone graft fusion group at 12 months after operation were higher than those of the prosthetic replacement group(P<0.05). There was significant difference in the incidence of axial symptoms of patients in two groups during the follow-up period(P<0.05). Conclusion: Compare with anterior cervical decompression and fusion with bone graft, the long-term effect of Bryan cervical disc prosthesis replacement for patients with cervical spondylotic myelopathy is better, it can better improve the biomechanics of the cervical vertebra and reduce the incidence of axial symptoms in the neck, which is worthy of clinical application.
