This study was designed to evaluate the relationship between minor trauma and surgical results of cervical ossification of the posterior longitudinal ligament (OPLL), focusing on static compressive and dynamic factors contributing to cord compression plus the type of attendant OPLL. Of the 91 patients treated surgically, 26 had sustained minor trauma (injury group), and the other 65 had no trauma (noninjury group). The pre-/postoperative JOA scores and recovery ratio for the injury group were significantly lower than those for the noninjury group. In the segmental, localized, and mixed types, which had good ranges of motion of the cervical spine, the recovery ratios of the injury group were significantly lower than those of the noninjury group. In the continuous type, which had a poor range of motion and severe spinal cord compression, there was no significant difference in the recovery ratio between the injury and noninjury groups. Thus, dynamic factors may play an important role in neurologic deterioration after minor trauma in patients with segmental, mixed, and localized cervical OPLL.
本研究旨在评估轻微创伤与后纵韧带骨化症（OPLL）手术结果之间的关系，重点关注导致脊髓受压的静态和动态因素以及伴随的OPLL类型。在91例接受手术治疗的患者中，26例遭受过轻微创伤（损伤组），另外65例无创伤（非损伤组）。损伤组术前/术后的JOA评分及恢复率显著低于非损伤组。在颈椎活动度良好的节段型、局限型和混合型中，损伤组的恢复率显著低于非损伤组。在活动度差且脊髓受压严重的连续型中，损伤组与非损伤组的恢复率无显著差异。因此，动态因素可能在节段型、混合型和局限型颈椎OPLL患者轻微创伤后神经功能恶化中起重要作用。
