Surgical strategy used in multilevel cervical disc replacement and cervical hybrid surgery: Four case reports

Figure 2 Computed tomography images of case 2. A and B: Lateral radiographs taken before surgery revealed that the range of motion at C5/6 was decreased (2.57°), while the range of motion at C4/5 and C6/7 was 9.34° and 6.05°, respectively. The intervertebral disc height at C4/5 was preserved; C: Large numbers of osteophytes were revealed at the posterior-inferior border of C5 and C6; D: Magnetic resonance imaging indicated spinal cord compression at C4/5, C5/6, and C6/7, and compression at C4/5 was caused by disc herniation.
