TERMINOLOGY
Definitions
- Hallux: great toe; 1st digit of foot
- Hallux valgus deformity: 1st metatarsophalangeal (MTP) angle > 15°
- Hallux valgus is well-entrenched misnomer
- Valgus refers to deformity in vertical plane, apex medial
- Hallux valgus is deformity of 1st MTP joint in horizontal plane, apex medial
- Correct term would be hallux abductus
- Some sources use term hallux abductovalgus
- Metatarsus primus varus is also misnomer
- Varus is deformity in vertical plane, apex lateral
- Metatarsus primus varus is deformity of 1st tarsometatarsal (TMT) joint in horizontal plane, apex lateral
- 1st intermetatarsal angle > 10°
- Some sources use term metatarsus primus adductus
- Both terms are widely used, acceptable
- Morton foot or toe: 2nd metatarsal developmentally longer than 1st
