Abstract

Abstract:

BACKGROUND: Anterior cervical spine plate fixation is believed to be the standard method for the treatment of cervical anterior segmental discectomy and fusion, however, anterior cervical plate implants has a lot of risk related to metal implants complications.
OBJECTIVE: To analyze and compare the effectiveness of the application of double-way connection intervertebral fusion device and Cage intervertebral fusion device+anterior cervical plate fixation for anterior above two-level cervical interbody fusion.
METHODS: Fifty-four patients with above two-level cervical intervertebral disc herination were treated with anterior cervical decompression and fusion. These patients were treated with anterior cervical interbody fusion using double-way connection intervertebral fusion device (n=30) and Cage intervertebral fusion device and anterior plate fixation system (n=24). The clinical results were evaluated with Japanese Orthopedic Association scale scores, and the cervical curvature, intervertebral height and cervical fusion state were tested with X-ray film at 3 and 6 months after interbody fusion.
RESULTS AND CONCLUSION: All patients were followed-up for 6 months. The patients in two groups got osseous fusion, and the average fusion time was 5.5 months. Average Japanese Orthopedic Association scale score of double-way connection intervertebral fusion device group was increased from (7.4±0.4) preoperatively to (14.3±0.5) at 3 months and (14.5±0.8) at 6 months postoperatively; and the average Japanese Orthopedic Association scale score of Cage intervertebral fusion device group was increased from (7.6±0.7) preoperatively to (13.9±0.4) at 3 months and (14.0±0.6) at 6 months postoperatively, and the differences were significant. The spinal curvature and intervertebral height were significantly improved after treatment. This procedure can effectively restore cervical lordosis, obviate the complications related to graft harvest and screw-plate fixation, and lead to satisfactory outcomes.
