An imaged-based three-dimensional study of first metatarsal protrusion distance in women with and without hallux valgus

An Imaged-Based Three-Dimensional Study of First Metatarsal Protrusion Distance in Women With and Without Hallux Valgus First metatarsal protrusion distance (MPD) has been commonly studied as a characteristic of hallux valgus deformity. To date, the majority of investigations have used radiographic methods, with most reporting first metatarsal (ray) protrusion to be associated with deformity. As an alternative, this study used a three dimensional (3D) image acquisition and data analysis method to quantify MPD.
