Periprosthetic femoral fracture (PPF) is a major complication following total hip arthroplasty (THA). Uncemented femoral components are widely preferred in primary THA, but are associated with higher PPF risk than cemented components. Collared components have reduced PPF rates following uncemented primary THA compared to collarless components, while maintaining similar prosthetic designs. The purpose of this study was to analyze PPF rate between collarless and collared component designs in a consecutive cohort of posterior approach THAs performed by two high-volume surgeons.

将做法改为新一代三锥度股骨假体可降低初次全髋关节置换术后假体周围骨折的发生率。

假体周围股骨骨折（PPF）是全髋关节置换术（THA）后的主要并发症。非骨水泥股骨假体在初次全髋关节置换术中广受青睐，但与骨水泥假体相比，其 PPF 风险更高。与无环组件相比，有环组件降低了未骨水泥初次 THA 后的 PPF 率，同时保持了类似的假肢设计。本研究的目的是分析在由两名高手术量外科医生进行的连续队列后入路 THA 中无环和有环组件设计之间的 PPF 率。
