The aim of this study is to evaluate the intraarticular lesions, to identify fractures specifically at risk for these, and to assess the results following arthroscopically assisted open reduction and internal fixation of complex ankle fractures prospectively.
Starting 05/01/13 patients with complex ankle fractures, older than 17 years, who sustained the injury less than 14 days before surgery and giving informed consent are consecutively enrolled. A complex fracture is defined as either an isolated malleolar fracture in combination with ligamentous instability, or a bi- or trimalleolar fracture. An unstable ligamentous injury is defined as either a disruption of the deltoid ligament leading to increased medial talar tilt, or an unstable syndesmotic injury assessed by the external rotation test both after osteosynthesis of all fractures. Exclusion criteria are isolated unimalleolar fractures, pilon fractures, open fractures, multiple injuries, mental illness, incompliance or pregnancy. Data assessed are: * Demographics * Medical history * Classification (AO, Haraguchi, ICRS, location and size defect) * Surgery details * Complications * PROMs (FAAM, AOFAS, OMAS, FAOS, TAS, SF-12, EQ-5d, MoxFQ)
