[Fractures of the tarsal navicular bone (author's transl)].

Analysing 17 cases of navicular fracture, authors divide the fracture dislocations in two groups. The importance of X-ray pictures in oblique views and the frequent occurence of simultaneous foot injuries is pointed out. On follow up examination of 13 fractures 3--8 years after injury authors observed in general severe arthritis, subjective impressions of the patients and the results of rehabilitation on the other hand were satisfactory. Their result suggest in cases of dorso-medial dislocation, in order to avoid redislocation, a wire pinning or open screw fixation or rather as an exception primary desis. In cases of lateral dislocation the fracture is not prone to redislocation therefor a conservative treatment is sufficient.
