A total of 488 fractures of the ankle are described and classified into types and stages according to Lauge Hansen (1942). The classification was partly based on operative findings. The type division was: supination-eversion fractures 57.4 per cent, supination fractures 20.1 per cent, pronation and pronation-eversion fractures 20.1 per cent and pronation-dorsiflexion fractures 0.4 per cent. ⋯ It was found that the stage 2 injury in pronation and pronation-eversion fractures is not fully explained by Lauge Hansen. The classification of Lauge Hansen gives a very exact description of ankle fractures. This is very important for the operative treatment and also indispensable for the evaluation of the results of various methods of treatment.

Follow-up data for at least 4 years was collected for 675 patients treated for hip fractures in the period 1961--1970. Compared with a series from the same hospital for the years 1948--1957 the number of patients had more than doubled and a higher hospital mortality was encountered, but the 4-year survival rate was unchanged. The mortality after hip fracture was found to be related to the age and sex of the patient and to the nature and number of associated diseases. The mortality rate was found to be high in the first 2 months following the fracture, but patients surviving the second month showed no excess mortality during the following 4 years, having the same life expectancy as the general population.
