The Arbeitsgemeinschaft fur Osteosynthese fragen Spine Sacral Injury Classification hierarchically separates fractures based on their injury severity with A-type fractures representing less severe injuries and C-type fractures representing the most severe fracture types. C0 fractures represent moderately severe injuries and have historically been referred to as nondisplaced “U-type” fractures. Injury management of these fractures can be controversial. Therefore, the purpose of this narrative review is to first discuss the Arbeitsgemeinschaft fur Osteosynthese fragen Spine Sacral Injury Classification System and describe the different fracture types and classification modifiers, with particular emphasis on C0 fracture types. The narrative review will then focus on the epidemiology and etiology of C0 fractures with subsequent discussion focused on the clinical presentation for patients with these injuries. Next, we will describe the imaging findings associated with these injuries and discuss the injury management of these injuries with particular emphasis on operative management. Finally, we will outline the outcomes and complications that can be expected during the treatment of these injuries.

Arbeitsgemeinschaft fur Osteosynthese fragen Spine Sacral Injury Classification 根据骨折的严重程度对骨折进行分级，A 型骨折代表不太严重的损伤，C 型骨折代表最严重的骨折类型。C0 骨折代表中度严重损伤，历史上被称为无移位的“U 型”骨折。这些骨折的损伤处理可能存在争议。因此，这篇叙述性综述的目的是首先讨论 Arbeitsgemeinschaft fur Osteosynthese fragen 脊柱骶骨损伤分类系统并描述不同的骨折类型和分类修饰符，特别强调 C0 骨折类型。然后，叙述性综述将侧重于 C0 骨折的流行病学和病因学，随后的讨论侧重于这些损伤患者的临床表现。接下来，我们将描述与这些损伤相关的影像学表现，并讨论这些损伤的损伤处理，特别强调手术处理。最后，我们将概述在治疗这些损伤期间可以预期的结果和并发症。
