Despite numerous biomechanical and clinical studies on ankle fractures, the optimal treatment method for a stable fibula fracture is poorly known. Additionally, the clinical relevance and optimal fixation method of syndesmosis injury for different ankle fracture types is unclear. This thesis aimed: (I) to compare six weeks of cast immobilization with three weeks of immobilization (cast or orthosis) in a randomized controlled trial (RCT) of 247 patients with stable Weber B-type fibular fracture; (II) to compare mid-term outcome of syndesmosis transfixation with no fixation in an RCT of 24 patients with supination external rotation (SER) ankle fractures and syndesmosis injury; (III) to evaluate the significance of the syndesmosis injury on clinical outcome in a case-control study of 48 patients with SER ankle fractures; and (IV) to compare the syndesmosis fixation with a screw versus a suture-button device in terms of the accuracy and the maintenance of syndesmosis reduction in an RCT of 43 patients with pronation external rotation (PER) ankle fractures. Three weeks of immobilization in either a cast or an orthosis resulted in non-inferior outcomes compared to traditional six weeks’ immobilization in patients with stable Weber B-type fibula fracture. In patients with SER ankle fracture and unstable syndesmosis after fixation of bone fractures, leaving unstable syndesmosis unfixed resulted in similar outcomes compared to syndesmosis transfixation at mid-term follow-up. Patients with SER ankle fractures with or without an associated syndesmosis injury had similar clinical outcomes after a minimum of four years of follow-up. The syndesmotic screw and the suture-button fixation in patients with PER ankle fracture and unstable syndesmosis resulted in a low malreduction rate and both methods maintained reduction well. In conclusion, stable Weber B-type fibula fractures can safely be treated with only three weeks of cast immobilization or even with a simple orthosis. A syndesmosis injury in SER ankle fractures seems to be of minor therapeutic or prognostic importance and syndesmosis screw fixation has no effect on patient’s recovery compared to no syndesmosis fixation. An associated syndesmosis injury in PER ankle fractures can be fixed with a syndesmotic screw or a suture-button device with comparable outcomes.
