Periprosthetic Fracture

Total hip arthroplasty (THA) is an orthopedic technique which relieves pain and improves hip function in the early postoperative period and is commonly regarded as the greatest invention in the field of orthopedic surgery in the twentieth century [1]. However, the incidence of periprosthetic femoral fractures (PFF), particularly peri-stem fractures, has been increasing in the aging population [2, 3]. According to the UK registry, the incidence of PFF increased by 2.2% during the 3-year period from 2012 to 2015 [2], while the US registry predicted an increase of 4.6% every 10 years for the next 30 years [3]. The mortality rate within 6 months after revision for PFF following THA was reported to be 7.3%, compared with the mortality rate of 0.9% for elective revision THA. PFF is therefore a serious complication that should be avoided [4].
