Objective To retrospectively analysis and compareabout Bryan artificial cervical disc arthroplasty with ante-rior cervical decompression and fusion (ACDF) on the clinical efficacy for“Skip”cervical spondylosis. Methods From February 2002 to May 2012, 49 cases were treated with Bryan artificial cervical disc arthroplasty (artificial cervical disc replacement surgery group, 18 cases) or anterior cervical decompression and fusion (ACDF group, 31 cases), 29 males and 20 females. Each case was evaluated at the moment of preoperatively, 3 months, 6 and 12 months and last follow-up after surgery by the Japanese Orthopedic Association (JOA), Neck Disability Index (NDI), Visual Analog Scale (VAS), Cervical sagittal curvature, the total cervical spine range of motion(ROM),middle segments of motion. MRI was also used to assess to adjacent segment disc degeneration, spinal cord compression and signal change situation. Results All patients were followed up for more than 24 months. The score of the JOA, NDI, VAS in the two groups of patients improved significantly after surgery than before surgery. In addition, the VAS score in last follow-up were significantly different between the two groups, but other index each time in the two groups showed no significant difference. In last follow-up, the result of artificial cervical disc arthroplasty group were better than ACDF group on the incidence of axial symptoms, the total cervical spine range of motion (ROM) and middle segments of motion. The incidence of axial symptoms in artificial cervical disc arthroplasty group were 11.1%,ACDF group were 45.2%. ROM in arti-ficial cervical disc arthroplasty group were 35.5°±5.9°,ACDF group were 24.5°±6.2°. Middle segments of motion in artificial cer-vical disc arthroplasty group were 7.3°±1.4°,ACDF group were 10.1°±1.6°. The above comparison of the datas were statistically different. There are two cases of adjacent segment degeneration in ACDF group without need to surgery. Conclusion Bryan artifi-cial cervical disc replacement surgery effectively retained the overall motion of the cervical spine, reduced the motion of middle segments, thus avoiding adjacent segment degeneration and the incidence of postoperative axial symptoms.
