Outcome Measures

Primary Outcomes (1)

  • range of the motion of operative segments and adjacent segments

    Standard dynamic flexion and extension lateral cervical radiographs were obtained to evaluate range of motion of C2-C7 and operative segments and superior and inferior adjacent segments, cervical lordosis, and radiographic changes in adjacent segments.

    preoperatively, within 5 days after surgery, and at 6, and 12 months postoperatively

Secondary Outcomes (3)

  • scores of the Japanese Orthopedic Association

    preoperatively, within 5 days after surgery, and at 6, and 12 months postoperatively

  • scores of the Neck Disability Index

    preoperatively, within 5 days after surgery, and at 6, and 12 months postoperatively

  • scores of the visual analog scale

    preoperatively, within 5 days after surgery, and at 6, and 12 months postoperatively

Study Population

patients with bi-level cervical spondylosis

You may qualify if:

  • (1) Cervical degenerative pathology with symptomatic radiculopathy or myelopathy at two consecutive segments from C3 to C7 which not responding to conservative treatment for 6 weeks. (2) Preoperative magnetic resonance imaging (MRI), complete cervical spine radiography and computed tomography (CT) showed anterior compressive pathology. (3) None or slight osteophyte at the posterior edge of vertebrae. (4) None significant spinal stenosis or posterior compression.

You may not qualify if:

  • ossification of the posterior longitudinal ligament (OPLL), tumor, fracture, infection, history of cervical spine surgery, narrowing of the spinal canal, and any serious general illness. Cases with one or more than two segments requiring treatment were also excluded.
