OUTCOMES OF INTERBODY FUSIONAND ARTHROPLASTY FOR CERVICAL SPINE DEGENERATIVE DISEASE

Abstract

Objective.To compare the results of interbody fusion and arthroplasty in patients with cervical spine degenerative disease.Material and Methods.Thirty-seven Bryan cervical discs prosthesis were implanted in 31 patients after discectomy (Group 1). Interbody fusion was performed in 47 patients (Group 2). Comprehensive survey of all patients was performed preoperatively, immediately postoperatively, at 3, 6, 9, 12, and 24 months after surgery. A visual analogue scale (VAS), the scale of disability assessment, radiography, MSCT, and MRI were used.Results.VAS assessment showed that in patients from Group 1 the pain relieved in the arm by 62.37 %, in the neck – by 38.75 %, and in Group 2 in the arm – by 38.75 % and in the neck – by 35.59 %. Quality of life improved by 53.18 % in Group 1 and by 30.34 % in Group 2. Adjacent segment degeneration within 24 months after surgery was observed in 5.30 % of patients from Group 1 and in 55.00 % of patients from Group 2. There were no subsidence and displacement of prostheses in the Bryan Group. In the Group of interbody fusion 35.00 % of patients showed subsidence and nonunion between implants and vertebrae of the operated segment.Conclusion.Arthroplasty provided better clinical and radiographic results in early and long-term postoperative periods.
