Purpose:The purpose of this study is to find out the normal results in ankle on varus stress, valgus stress, and anterior draw stress in young men in korea. This would be helpful as the basic data of measuring of ankle instability for operational indication.
Material and Methods : Varus and Valgus stress anteroposterior radiographs and Anterior drawing stress lateral radiographs of 600 normal ankles were reviewed. First, A line parallel was drawn parallel to the articular surface of the distal tibia, and another line was drawn parallel to the articular surface of the talus on anteroposterior radiographs. The interior angle that subtended by these two lines was measured. Second, the reference point is located at the posterior border of the tibia, and the shortest distance from this point to the proximal posterior articular surface of the talus is measured.
Results: There were 300 males and 600 ankles. The mean age overall was 21 years (19-22 years) old. The mean length of ankle on anterior draw stress was 5.54±3.33 mm. The mean a interior angle of ankle on varus stress was 0°-8.93°, and on valgus stress 0°-7.78°.
Conclusion:We can consider for operational indication at over the 8.87 mm on anterior draw stress, over the 8.93°on varus stress, and over the 7.78° on valgus.
