Abstract

PURPOSE
The purpose of this study is to find out the normal angles of the talus-1st metatarsal angle, the talo-horizontal angle and calcaneal pitch angle for diagnosis of foot deformity in Korea. This would be helpful as it would provide a basic angular measurement of flat and cavus foot that indicates the need for operation.
MATERIALS AND METHODS
Within a period of four months from January 2007 to April 2007, We have established 600 feet of 300 males without trauma history of foot. The source to image distance is 40 inches and erect weight bearing radiographs are obtained in anteroposterior and lateral projections. The significant angular measurements that define flat or cavus foot are the talus-1st metatarsal angle, the talo-horizontal angle and calcaneal pitch angle.
RESULTS
The mean age was 21 years (19-22 years) old. The mean talus-1st metatarsal angle was 0+/-6.9degrees, the mean talo-horizontal angle was 25.8+/-4.5degrees and the mean calcaneal pitch angle was 23.9+/-5.1degrees.
CONCLUSION
We can consider that mean talus-1st metatarsal angle, talo-horizontal angle and calcaneal pitch angle are 0+/-6.9degrees, 25.8+/-4.5degrees and 23.9+/-5.1degrees as an normal angle limit of young age in Korea.
