To discuss the history, indication, surgical outcomes, prognostic factors, and complications of laminoplasty for ossification of the posterior longitudinal ligament (OPLL) of the cervical spine.
OPLL usually requires surgery, which often involves indirect decompression by the posterior approach. Of the posterior procedures for OPLL, laminoplasty is the favored treatment. Here, we review the previously published literature on laminoplasty for OPLL.
PubMed and previously published English and Japanese book chapters were searched for posterior procedures for treating OPLL.
There is a large body of literature on OPLL and its treatment. Based on a review of the literature, the history, indication, surgical outcomes, prognostic factors, and complications of laminoplasty for OPLL were examined. The results showed that long-term outcomes of both the open-door and double-door types of laminoplasty are favorable, although late neurological deterioration occurs in some patients. Preoperative kyphosis of the cervical spine and severe (>60%) compromise of the spinal canal by OPLL appear to be the limiting factors for the indication of laminoplasty. Complications of laminoplasty include segmental motor palsy, lamina closure, and axial symptoms.
Laminoplasty is a feasible surgical option for OPLL if candidate patients are appropriately selected.
研究设计：综述文章。
目的：讨论颈椎后纵韧带骨化症（OPLL）的椎板成形术的历史、适应证、手术结果、预后因素和并发症。
背景资料总结：OPLL 通常需要手术治疗，通常采用后路间接减压。在 OPLL 的后路手术中，椎板成形术是首选的治疗方法。在这里，我们复习了关于 OPLL 椎板成形术的已发表文献。
方法：在 PubMed 和以前发表的英文和日文章节中搜索了治疗 OPLL 的后路手术。
结果：有大量关于 OPLL 及其治疗的文献。通过对文献的回顾，检查了 OPLL 椎板成形术的历史、适应证、手术结果、预后因素和并发症。结果表明，尽管一些患者出现晚期神经恶化，但开门式和双开门式椎板成形术的长期结果都是良好的。颈椎术前后凸和 OPLL 对椎管的严重（>60%）压迫似乎是椎板成形术适应证的限制因素。椎板成形术的并发症包括节段性运动麻痹、椎板闭合和轴向症状。
结论：如果合适的患者选择，椎板成形术是治疗 OPLL 的可行手术选择。
