Modular femoral and acetabular components are frequently used in hip arthroplasty. Although the use of modular components offers many advantages, the increased number of components leads to a high risk of disassembly. Disassociation of the femoral head and neck is a rarely reported complication in the literature. This case report depicts a patient with non-traumatic early disassociation of the femoral head and neck components following total hip revision arthroplasty. Femoral head-neck disassembly in early postoperative period may occur due to manufacturing error or insufficient impaction. If sufficient impaction is thought to be achieved, manufacturing errors should be kept in mind as potential underlying reasons for femoral head-neck dissociation.
模块化股骨和髋臼组件常用于髋关节置换术。尽管使用模块化组件有许多优点，但组件数量的增加导致了高拆卸风险。股骨头与颈部的分离是文献中报道较少的并发症。本病例报告描述了一名患者在全髋关节翻修置换术后出现非创伤性股骨头与颈部组件早期分离的情况。术后早期股骨头-颈部分离可能由于制造误差或压配不足而发生。如果认为已实现足够的压配，则应将制造误差视为股骨头-颈部分离的潜在根本原因。
