[The use of a new hook plate for the operate treatment of ankle fractures (author's transl)].
Authors describe their methods of treatment and results in 137 inpatients with ankle fractures treated during a period of one and half year. Analysing this material the indications and methods of surgical treatment for ankle fractures are dealt with. In order to facilitate the surgical treatment of the most common type of ankle fractures (i.e. pronation fractures in group B of Weber) authors constructed a hook plate, adapted to the external malleolus, which proved good in their practice. Within this material it was used for 38 patients. 77 per cent of the displaced ankle fractures were treated surgically. After an average of 13.8 months follow up time the results were found satisfactory, using an evaluation system adequat for international comparison. With their data the efficiency of the surgical treatment for displaced ankle fractures is emphasized. The new hook plate is first of all used for the operative treatment of pronation fractures in level of the syndesmosis, and is recommended on basis of good experiences.
