Fig. 3From: Etiological factors in hallux valgus, a three-dimensional analysis of the first metatarsalComparison of the mean torsional angle of the 1MT between the control and HV groups. The mean torsional angle of the 1MT is significantly larger in the HV group (17.6 ± 7.7°) than in the control group (4.7 ± 4.0°; p < 0.01)Back to article page
