Traumatic posterior occipitocervical dissociation (OCD) is a rare injury, and only a few cases have been reported in the literature. The diagnosis can be delayed or even missed because of its uncommon presentation. We present this rare case report and its management to highlight this unusual injury to increase the awareness of the existence of this pathology and prevent delayed diagnosis and treatment.
A 76-year-old man was brought to the emergency room with complaints of neck pain. There was a history of trivial trauma before this complaint. The cervical spine images revealed an anterior subluxation of the cervical spine with Jefferson burst fracture involving bilateral fractures of anterior and posterior arches, C5-6 transdiscal fracture, underlying ossification of the posterior longitudinal ligament (OPLL), and diffuse idiopathic skeletal hyperostosis (DISH). He was managed with closed reduction, occipitocervical fourth vertebra fusion (O-C4), and C1, C2 laminectomies with a good outcome.
Traumatic OCD can result from low-energy trauma. We report a rare case of posterior OCD that was associated with Jefferson fracture and predisposing factors, including OPLL and DISH.
创伤性枕颈后脱位（OCD）是一种罕见的损伤，文献中仅报道了少数病例。由于其表现不常见，诊断可能会延迟甚至漏诊。我们呈现这一罕见病例报告及其治疗方法，以突出这种不寻常的损伤，提高对这种病理情况存在的认识，并防止延迟诊断和治疗。
一名76岁男性因颈部疼痛被送往急诊室。此次主诉之前有过轻微外伤史。颈椎影像显示颈椎前脱位伴Jefferson爆裂骨折，累及双侧前后弓骨折、C5-6椎间盘骨折、后纵韧带骨化（OPLL）及弥漫性特发性骨肥厚（DISH）。他接受了闭合复位、枕颈第四椎体融合术（O-C4）以及C1、C2椎板切除术，效果良好。
创伤性OCD可由低能量创伤引起。我们报告了一例罕见的后OCD病例，该病例与Jefferson骨折以及包括OPLL和DISH在内的易感因素相关。
