Periprosthetic fracture can create significant morbidity in the arthroplasty population. Patients with periprosthetic fracture have been shown to have worse outcomes and higher mortality than patients undergoing elective revision THA. In this review, we will focus on Vancouver B2 and B3 fractures. Both of these fracture types are associated with a loose primary prosthesis and warrant revision surgery. There are many different options for fixation choice of the femoral prosthesis, and preference has been evolving over the last 30 years. Currently, we use monoblock, tapered, fluted, titanium stems for all periprosthetic fracture revision surgeries.
假体周围骨折会给关节置换人群带来严重的发病情况。与接受择期翻修全髋关节置换术的患者相比,假体周围骨折患者的预后更差,死亡率更高。在本综述中,我们将重点关注温哥华B2型和B3型骨折。这两种骨折类型均与初次假体松动相关,需要进行翻修手术。股骨假体固定选择有许多不同的方案,在过去30年里,人们的偏好一直在演变。目前,我们在所有假体周围骨折翻修手术中都使用一体式、锥形、带槽的钛柄。
