Abstract
We Clinically analysed 10 cases of fractures of the neck of the talus which had been treated at the Department of Orthopedic Surgery, Kyungbook Nantional University Hospital from 1984 to 1988 and the following results were obtained.
1. Of the 10 cases, Hawkiins type I was 2 cases, type II, 4 cases and type III, 4 cases.
2. Avascular necrosis was developed in 7 cases. 1 of type I, 3 of type II and 3 of type III.
3. In all 6 cases with comminution at subtalar and medial aspect of talus, avascular necrosis was developed.
4. Hawkins sign was evident in the plane roentgenogram from 5th weeks to 12th weeks(mean at 8th weeks) and we could diagnose the avascular necrosis of talar body at 9.3th weeks.
5. Bone scan was not a helpful diagnostic tool for the confirmation of the avascular necrosis of the talar body.
6. Absolute non-weight bearing is mandatory until solid union is obtained and partial weight bearing with PTB brace is advisable after emergence of the sign of revasculariztion on the plane roetgenogram.
7. Of the 10 cases of the fracture of the neck of the talus, satisfactory results were obtained in 7 cases and of the 7 cases with avascular necrosis, relatively good results were in 5 cases.
