The aim of this study was to evaluate the long-term clinical and radiographic outcomes of cervical arthroplasty using the ProDisc-C prosthesis.
Clinical and radiographic evaluations, including dynamic flexion-extension lateral images, were performed at baseline and at 10-year follow-up.
Twenty-seven patients who had single-level ProDisc-C arthroplasty were followed up for a mean period of 123 months. The range of motion at the operated level was 8.9° ± 3.9° at baseline and 6.6° ± 3.5° at final follow-up. Twenty of 27 levels (74%) developed heterotopic ossification. According to McAfee's classification, one level was classified as grade I, four levels were classified as grade II, 12 levels were classified as grade III and three levels were classified as grade IV. Three patients developed recurrent cervical radiculopathy or myelopathy due to adjacent segment disease and received the reoperations. The reoperations included two cases of cervical arthroplasty at adjacent segments and one case of cervical laminoplasty.
ProDisc-C arthroplasty had acceptable clinical and radiographic results at 10-year follow-up. Heterotopic ossification was common after ProDisc-C arthroplasty, which decreased the range of motion. These slides can be retrieved under Electronic Supplementary Material.
本研究旨在评估使用 ProDisc-C 假体进行颈椎关节置换的长期临床和影像学结果。
在基线和 10 年随访时进行临床和影像学评估，包括动态屈伸侧位图像。
27 例接受单节段 ProDisc-C 关节置换的患者平均随访 123 个月。手术节段的活动度在基线时为 8.9°±3.9°，在最终随访时为 6.6°±3.5°。27 个节段中有 20 个（74%）发生了异位骨化。根据 McAfee 分级，1 个节段为 I 级，4 个节段为 II 级，12 个节段为 III 级，3 个节段为 IV 级。3 例因相邻节段疾病出现复发性颈神经根病或颈椎病，接受了再次手术。再次手术包括 2 例相邻节段颈椎关节置换和 1 例颈椎椎板成形术。
ProDisc-C 关节置换在 10 年随访时具有可接受的临床和影像学结果。ProDisc-C 关节置换后异位骨化常见，这降低了活动度。这些幻灯片可在电子补充材料中检索。
