In plain words

What the trial is, and whether it could suit you

Ankle fractures constitute 9% of all fractures and have an incidence of approximately 187 per 100,000 persons per year in Norway. A posterior malleolar fragment (PMF), located on the lower backside of the tibia, is present in up to 46% of Weber B. Weber B fractures are the most common type of fractures of the fibula, located at the height of the syndesmosis. Patients with a PMF were recently shown to have significantly lower patient-reported outcome measures (PROM) than the general population. For this reason, the indication and choice of intervention for these fractures have been the object of increased interest over the recent years. It is one of the most debated areas within ankle fracture surgery. Traditionally, these PMFs have been treated with closed reduction, without direct manipulation of the PMF, anteroposterior screw fixation, or even no-fixation of the smaller fragments. A mo
