Purpose:The purpose of this study is to find out the normal distal tibial articular surface angle in coronal plane in Koreans. This would be helpful as the basic data for ankle reconstruction after trauma or deformity correction.
Material and Methods :Weight bearing anteroposterior radiographs of 123 normal ankles were reviewed. A line parallel to the shaft of the tibia was made. Another line was drawn parallel to the articular surface of the distal tibia. The superolateral angle that subtended by these two lines was measured.
Results: There were 72 males and 51 females. The mean age overall was 35.7 years old. The mean age for males was 31.9 (28~36) years old. The mean age for females was 41.1 (37~45) years old. The mean distal tibial articular surface angle was 90.8°. The mean distal tibial articular surface angle for males was 91.5° and for females 89.9°.
Conclusion:The mean distal tibial articular surface angle in coronal plane for Koreans is 90.8°. We can avoid the error of the varization at the ankle alignment when the correction was performed vertical or minimal valgus to tibia tuberosity axis in Korean people.
