Purpose:To investigate the relationship between radiographic parameters of the forefoot and plantar pressure in patients with hallux valgus.
Material and Methods : Plantar pressure of 21 patients with hallux valgus were examined with EMED-ST system. The data were compared with the parameters on the simple weightbearing dorsoplantar radiographs of the feet. The radiographic parameters that were measured were hallux valgus angle, 1-2 intermetatarsal angle, relative lengths of the metatarsals which were measured with the methods described by Maestro et al. and Okuda et al.
Results: Statistically significant correlation was found between peak pressures under 2,3 metatarsal heads and the relative lengths of 2, 3 metatarsals which were measured with the method described by Maestro et al. However they could explain only 13% of the pressure under the 2, 3 metatarsal heads by multivariate analysis.
Conclusions:These results suggest that we cannot predict the plantar pressures under the foot with the parameters on the simple weightbearing dorsoplantar radiographs of the feet.
