What is the normal hallux valgus angle?
What is the normal hallux valgus angle? An angle larger than 15° causes the hallux valgus deformity to appear more severe than it actually is. The normal upper limit for the HAA is 15-20°. This angle is the abduction of the longitudinal bisection of the proximal phalanx and first metatarsal; it is also known as the first-MTP angle. What radiograph finding is consistent with a valgus position of the first metatarsal? Plain radiograph A normal first metatarsophalangeal angle is ≤15° on an AP weight-bearing foot radiograph 2; anything greater indicates hallux valgus where the head of the first metatarsal is...
