未经授权:每年接受全髋关节置换术(THA)的患者数量不断增加,这些患者中有很大一部分是老年人,因此由于年龄原因,并发症的风险更高,骨质疏松,和医疗合并症。股骨假体周围骨折(PFFs)是THA最严重的并发症之一,预后不良率高。此外,在过去的十年里,美国骨与矿物研究协会(ASBMR)特别工作组已经确定并定义了一种新的独立疾病实体,称为"非典型股骨骨折"(AFF).一些PFF呈现的临床病史和影像学方面与AFF一致,符合ASBMR诊断AFF的标准,但PTFs本身是AFF的排除标准。然而,越来越多的已发表研究表明,股骨假体周围不典型骨折(PAFFs)存在,定义不应排除.
未经批准:如今,尽管人们对PAFF的兴趣越来越大,关于该主题的研究仍然很少,并且对其治疗缺乏共识。这篇叙述性文献综述旨在将这一新出现的主题介绍给更广泛的读者,以描述PAFF的特征及其管理中的最新技术。
UNASSIGNED:许多作者一致认为,PAFF应被视为具有非典型特征的PFF的一个亚组;它们还显示出与长期使用双膦酸盐的显着相关性。正确的诊断对于需要采取手术和医疗措施的疾病的正确治疗至关重要。
UNASSIGNED: An increasing number of patients is annually undergoing total hip arthroplasty (THA), and a significant proportion of these patients are elderly and consequently at a higher risk of complications because of age, osteoporosis, and medical comorbidities. Periprosthetic femoral fractures (PFFs) are one of the worst complications of THA associated with high rates of unfavorable prognosis. Besides, in the last decade, a new independent disease entity called \"atypical femoral fracture\" (AFF) has been identified and defined by the American Society for Bone and Mineral Research (ASBMR) task force. Some PFFs present clinical history and radiographic aspect consistent with an AFF, meeting the ASBMR criteria for the diagnosis of AFF except that PFFs by themselves are an exclusion criterion for AFF. However, there is an increasing number of published studies suggesting that periprosthetic atypical femoral fractures (PAFFs) exist and should not be excluded by definition.
UNASSIGNED: Nowadays, although there is an increasing interest in PAFFs, there are still very few studies published on the topic and a lack of consensus regarding their treatment. This narrative literature
review aims to introduce this new emerging topic to a wider readership describing the characteristics of PAFFs and the state-of-the-art in their management.
UNASSIGNED: Many authors agree that PAFFs should be considered as a subgroup of PFFs that have atypical characteristics; they also show a significant correlation with prolonged bisphosphonate use. A correct diagnosis is paramount for proper treatment of the disease that requires both surgical and medical actions to be taken.
