Hip fractures annually affect almost 20,000 patients in Sweden. In about 2,000 patients with displaced femoral neck fractures insertion of a total hip arthroplasty (THA) is the best available treatment. The THA can, however, dislocate, and around 8% of patients receiving a THA due to femoral neck fracture suffer from this painful complication that often requires revision surgery. In order to reduce the risk of dislocation "dual mobility cups" were developed, but the evidence supporting their use in hip fracture patients is weak.The purpose of this project is to evaluate whether dual mobility cups reduce the risk of dislocation in hip fracture patients treated with a THA within the setting of a registry-based, randomized clinical trial. Both inclusion of patients and randomization to intervention or control treatment are performed via the Swedish Fracture Register. The Swedish Hip Arthroplasty Register will be accessed to collect details on the surgical procedure, and primary and secondary outcomes will be collected from the National Patient Register .Population: 1,600 patients 65 years or older with a displaced femoral neck fracture who are eligible for a THAIntervention: Insertion of a dual mobility cupComparison: Insertion of a standard cupOutcomes: Primary outcome is the incidence of dislocations within one year. Secondary outcomes are re-operations for any reason, periprosthetic joint infections, 90- and 365-day mortality, patient-reported outcomes, and cost efficiency.
