ABSTRACT
STUDY DESIGN:
Retrospective case-control study.OBJECTIVES:
To compare the clinical and radiographic outcomes of a hybrid construct (HC) of cervical artificial disc replacement (CADR) combined with anterior cervical discectomy and fusion (ACDF) (group I) with 2-level ACDF (group II) in patients with 2-level cervical disc disease. SUMMARY OF LITERATURE REVIEW ACDF is reported to potentially promote degenerative changes in the adjacent segment. CADR has been expected to reduce the risk of adjacent segment degeneration. However, its clinical course has yet to be sufficiently clarified. MATERIALS ANDMETHODS:
Twenty-six patients underwent 2-level cervical disc surgery. Single-level CADR combined with ACDF was performed in 14 patients. Twelve patients underwent 2-level ACDF. Clinical profiles were assessed using the neck disability index (NDI) and visual analogue scale scores of arm and neck pain. Dynamic lateral cervical radiographs were obtained preoperatively and at 1, 6, 12, and 18 months postoperatively. The range of motion (ROM) of the overall cervical spine (C2-7) and the adjacent segments was measured.RESULTS:
Group I showed superior NDI 18 months postoperatively (p 0.05).CONCLUSIONS:
The HC group showed comparable clinical and radiographic outcomes to those of the 2-level ACDF group. HC can be used selectively in the treatment of patients with 2-level cervical disc disease.
