From 1989 to 1992, 43 of 174 (25%) consecutive North Americans had cervical ossification of the posterior longitudinal ligament (OPLL). After the non-random selection of anterior corpectomies and fusions, anterior discectomies and fusions, or five-level laminectomies, the preoperative and postoperative outcomes of the OPLL patients were compared using Ranawat's neurological classes and grades. Patients who had anterior OPLL surgery exhibited superior outcomes compared with those who had laminectomies. Specifically, the 20 patients who underwent corpectomies and had the most severe preoperative deficits, had the best postoperative results; the 13 discectomy patients, with the least severe preoperative deficits, had intermediate recoveries, whereas the ten laminectomy patients, with intermediate preoperative neurologic dysfunction, had biased future surgical choices to favor more anterior approaches.
1989年至1992年，174例连续的北美患者中有43例（25%）患有后纵韧带骨化症（OPLL）。在非随机选择前路椎体次全切除术及融合术、前路椎间盘切除术及融合术或五级椎板切除术后，使用拉纳瓦特神经学分类和分级方法比较了OPLL患者的术前和术后结果。接受前路OPLL手术的患者比接受椎板切除术的患者表现出更好的结果。具体而言，20例行椎体次全切除术且术前缺陷最严重的患者术后效果最佳；13例行椎间盘切除术且术前缺陷最轻的患者恢复情况中等，而10例行椎板切除术且术前存在中度神经功能障碍的患者在未来手术选择上倾向于更靠前的手术入路。
