A Radiographic Analysis of the Feet in Heel Pain

뒤꿈치 통증이 있는 족부의 방사선학적 분석

Purpose: This study is to compare the medial longitudinal arch between heel pain group and normal painless group. Materials and Methods: Heel pain group 242 feet and normal group 140 feet were evaluated through the radiographic images of standing foot-ankle lateral view. Four radiographic indices, talo-1stmetatarsal angle (TMA), calcaneal-1st metatarsal angle (CMA), calcaneal pitch angle (CPA), and arch ratio (AR), were used as well as BMI. Results: There was no difference between heel pain group and normal group in the TMA, CMA, CPA, and AR. But in the BMI, heel pain group showed $1.7\;kg/m^2$ (p=0.0002) higher than normal group. To eliminate the sexual error, male and female were evaluated separately. Male heel pain group showed 2.9 degrees more dorsiflexion (p=0.001) in the TMA, 3.1 degrees greater (p=0.007) in the CMA, 0.01 lower (p=0.028) in the AR, and $1.0\;kg/m^2$ greater (p=0.033) in the BMI than normal male group. There were no difference in the CPA. Female heel pain group showed 3.6 degree greater (p=0.035) in the CMA, and $1.9\;kg/m^2$ greater (p=0.002) in the BMI than normal female group. But other indices demonstrated no differences. Conclusion: talo-$1^{st}$ metatarsal angle, calcaneal-$1^{st}$ metatarsal angle and arch ratio were radiographic indices related with heel pain.
