Vancouver B型股骨假体周围骨折的治疗进展

Treatment progress of Vancouver type B periprosthetic femoral fractures

股骨假体周围骨折(PFFs)是行全髋关节置换术可能发生的一严重并发症,其造成的不良结果,往往会给患者带来极大的负担。目前,临床多采用Vancouver分型指导PFFs的治疗,其中以Vancouver B型治疗最为复杂,取决于多种因素,包括假体的类型、假体固定的机制和完整性、骨折类型和位置及周围剩余骨量。本文系统介绍了PFFs的流行病学、危险因素、分型与评估,讨论了Vancouver B型PFFs的治疗原则及治疗方式。期望临床医生对PFFs的诊断和治疗能有更充分的了解。

Periprosthetic femoral fractures is a potentially serious complication of total hip arthroplasty,and the adverse results will place serious health burden on patients.Currently,the Vancouver classification is used to guide the management of PFFs,and the evaluation and treatment of Vancouver type B fractures is also the most complex,depending on a variety of factors,including the type of prosthesis,the mechanism and integrity of prosthesis fixation,the type and the location of the fracture,and the amount of residual bone around prosthesis.This review introduces the epidemiology,risk factors,classification and evaluation of PFFs,and discusses the principles and methods of treatment for Vancouver type B PFFs.It is expected that clinicians will have a better understanding of the diagnosis and treatment of PFFs.
