Purpose: In order to achieve successful outcome for the hallux valgus surgery, it is mandatory to consider the possible associated hallux valgus interphalangeus, and therefore the hallux interphalangeal angle (HIA) other than hallux valgus angle (HVA) and intermetatarsal angle (IMA) has been well appreciated. The purpose of this study is to evaluate the incidence of hallux interphalangeal angle in the normal and hallux valgus feet and also the statistical correlations of HIA with HVA and IMA in the 2 groups. Materials and Methods: The study is base on the standing foot AP radiographs of the 100 normal feet (HVA<$12^{circ}$ 수식 이미지 and $IMA 수식 이미지<9^{circ}$ 수식 이미지) and 100 hallux valgus feet (HVA>$25^{circ}$ 수식 이미지 and IMA>$12^{circ}$ 수식 이미지). We measured the hallux valgus angle, intermetatarsal angle and hallux interphalangeal angle, where we defined the hallux valgus interphalangeus when the HIA was more than $10^{circ}$ 수식 이미지. We evaluated the incidence of the hallux valgus interphalangeus in the normal and hallux valgus groups and the correlations of the HIA with HVA and IMA. Results: In normal feet group, hallux valgus interphalangeus comprised 82%, while there were only 20% of HVI in hallux valgus group. Among 200 total feet, there was negative correlations between the HVA and HIA as well as IMA and HIA statistically (p<0.01). Conclusion: There was lower incidence of hallux valgus interphalangeus in the hallux valgus group compared to the normal feet group.
