FOREFOOT PRESSURES DURING WALKING IN FEET AFFLICTED WITH HALLUX-VALGUS

Forefoot pressures during walking in feet with hallux valgus were reco rded using pressure-sensitive film, and the relationships between defo rmities and foot pressures were analyzed, There were 32 female subject s comprising 50 feet with hallux valgus, of which 20 feet underwent su rgery, As in normal feet, the pressure patterns of feet with hallux va lgus were varied: peak pressures were under the first metatarsal head, under the second and/or third metatarsal heads, and the first, second , and/or third metatarsal heads, Peak pressures of hallux valgus feet were larger in each type than those of the normal foot, In feet with h allux valgus showing peak pressures under the first metatarsal heads, the hallux valgus angle and the intermetatarsal angle were larger than those in feet showing peak pressures on the second and/or third metat arsal heads, After surgery, peak pressures were under the second and/o r third metatarsal heads and they decreased.
