Abstract:
Objective To evaluate the clinical outcome of artificial cervical disc arthroplasty combined with anchoring cervical intervertebral fusion cage (ACIFC) in the treatment of multilevel cervical disc herniation. Methods From October 2011 to September 2013, 0.26 patients with multilevel cervical disc herniation underwent artificial cervical disc arthroplasty combined with ACIFC, there were 10 male and 16 female with age from 32 to 60 years (mean 46.8 years). Two segment were involved in 15 patients, three segment were involved in 11 patients. Neck disability index (NDI) and Japanese Orthopaedic Association (JOA) score were used to evaluate neurofunctional recovery preoperatively and postoperatively. The postoperative stabilization and the range of motion (ROM) of implanted disc and the fusion of cage were observed on dynamic radiograph. Results The average operation time and amount of bleeding were (95±15) min and (100±20) ml respectively. The average postoperative follow-up was 15 months(range 6-20 months). At the end of follow up,the scores of JOA was increased and the scores of NDI was decreased:(9.08±1.72) scores vs. (14.88±1.37) scores, (40.31±4.97) scores vs. (25.23±4.10) scores,there had significant differences (P<0.05). The change of ROM had no significant difference ( P>0.05). Solid fusion was achieved in all levels brought by cage.There was no cage subsidence or displacement. All artificial cervical disc achieved definite stabilization, no intraoperative and postoperative complication was noted. Conclusions Artificial cervical disc arthroplasty combined with ACIFC provides a feasible way for the treatment of multilevel cervical disc herniation. The definite stabilization and maintained ROM can reduce the fusion segments and avoid the increased stress of adjacent segment which can ensure a good preliminary clinical outcome.
