Abstract：
UNASSIGNED: Choi IIIB sequela (pseudarthrosis of femoral neck) is an uncommon complication of septic hip. Only few cases are reported in literature and experience with the entity is limited. Variable pseudarthrosis behaviour and treatment outcomes are reported questioning the mechanical etiology for Choi III sequela.
UNASSIGNED: We briefly analysed the relevant literature and propose two different pathomechanism for the entity. Three illustrative cases in support of proposed etiology are presented.
UNASSIGNED: There seems to be two distinct mechanisms of pseudarthrosis formation in Choi IIIB. The originally described mechanism is the articulating head getting dissociated from proximal femur due to a mechanical cause. The second proposed mechanism is the damage of physis and adjoining metaphysis by the septic inflammatory process (Choi II type sequela).
UNASSIGNED: It is important to understand the possible etiologies in Choi IIIB pseudarthrosis as the treatment planning and outcomes may vary. It will also help in prognostication.

摘要：
■ChoiIIIB后遗症（股骨颈假关节）是感染性髋关节的罕见并发症。文献中仅报道了很少的病例，该实体的经验有限。据报道，可变的假关节行为和治疗结果质疑ChoiIII后遗症的机械病因。
■我们简要分析了相关文献，并提出了该实体的两种不同病理机制。提出了三个支持拟议病因的说明性案例。
■在ChoiIIIB中似乎有两种不同的假关节形成机制。最初描述的机构是由于机械原因而使铰接头部与股骨近端分离。第二种提出的机制是败血症炎症过程（ChoiII型后遗症）对physis和毗邻的干phy端的损害。
■了解ChoiIIIB假关节的可能病因很重要，因为治疗计划和结果可能会有所不同。它也将有助于预测。
