Occipital condyle fractures (OCF) are commonly identified in patients suffering from severe craniocerebral trauma. Here, we present a 57-year-old male whose computed tomography (CT)-documented atlanto-occipital dislocation (AOD), due to just minor trauma was successfully managed with bracing alone.
A 57-year-old male presented with the right upper neck pain following a motor vehicle accident. The screening cervical CT scan revealed a fracture of the right occipital condyle, while the subsequent dynamic X-rays showed no instability or AOD. The patient was treated with a hard cervical collar, and over the next 6 months, remained asymptomatic. The 6-month repeat craniocervical CT scan additionally confirmed spontaneous fusion at the fracture site.
Patients who have sustained even mild craniocervical trauma may develop AOD attributed to an OCF. It is critical to screen these patients early with CT and X-ray studies so they can be successfully managed with bracing alone, and avoid the need for surgery to address the delayed onset of instability.
枕髁骨折（OCF）常见于重度颅脑创伤患者。在此，我们报告一名57岁男性，其因轻微外伤导致的寰枕关节脱位（AOD）经CT证实，仅通过支具治疗就成功治愈。
一名57岁男性在机动车事故后出现右上颈部疼痛。颈椎CT筛查显示右侧枕髁骨折，而随后的动态X线检查未显示不稳定或寰枕关节脱位。患者接受了硬颈托治疗，在接下来的6个月里一直无症状。6个月后的重复颅颈CT扫描进一步证实骨折部位自发融合。
即使是轻度颅颈创伤的患者也可能因枕髁骨折而发生寰枕关节脱位。早期对这些患者进行CT和X线检查至关重要，这样他们仅通过支具就能成功治疗，避免因不稳定延迟发作而需要手术治疗
