Fig. 1From: Effect of preoperative segmental range of motion on patient outcomes in cervical disc arthroplastyA patient underwent CDA at C6/7 using Prestige-LP discs in the small-ROM group. Preoperative segmental ROM was measured at 3.48° using lateral flexion-extension X-rays (a and b). Preoperative MRI demonstrated disc herniation at C6/7 (c and d). X-rays at 50 months follow-up (e and f) showing increased segmental mobility (ROM = 9.50°) at the arthroplasty segmentBack to article page
