Case Discussion

Metatarsus adductus is a condition with the following features:

  • medial displacement of the metatarsals on the cuneiform
  • forefoot is adducted at the tarsometatarsal joint
  • usually seen in the first year
  • is bilateral in 50% of patients, may be associated with hip displasia
  • is caused by intrauterine position

Regarding treatment, metatarsus adductus resolves with conservative treatment in >80% of cases. Casting may be used  in patients, refractory to conservative treatment, up to the age of five. Rarely tarsometatarsal releases or metatarsal osteotomies are required.
