A prospective nationwide cohort using the Swedish National Hip Arthroplasty Register, analyzing 321 periprosthetic femoral fractures reported in 1999–2000. The study characterizes patient demographics, incidence, Vancouver fracture classification reliability, treatment patterns, and mid-term reoperation-free survival across primary and revision arthroplasty groups.
When you see a Vancouver type-B fracture and radiographs leave stem stability in doubt, explore the joint intraoperatively — this registry shows that preoperative B1 classification is wrong nearly two-thirds of the time, and treating a loose stem with ORIF alone is the leading driver of a 25% reoperation rate within 5.5 years.
In patients with cemented primary THA, also consider implant design: Charnley and Exeter stems carried significantly higher fracture risk than the anatomically shaped Lubinus SPII, a factor worth weighing at index implant selection.
