Skewfoot is a late sequelae of which deformity?

• A. Metatarsus adductus
• B. Clubfoot
• C. Pes planus
• D. Hallux valgus

Answer: (A)

Skewfoot develops when forefoot adduction from metatarsus adductus persists and alters the normal alignment between the forefoot and hindfoot as a child grows. Metatarsus adductus is the inward turning of the forefoot due to abnormal development early in life; if this adduction remains, it can cause changes in midfoot and tarsometatarsal joints, producing a diagonal, rotated foot appearance—what clinicians call skewfoot.

This is the best match because skewfoot originates from the forefoot deformity (forefoot adduction) and represents a late consequence of that abnormal alignment. The other choices describe different primary deformities: clubfoot is a complex hindfoot/equinus problem with varus components; pes planus refers to a flat arch; hallux valgus is a first metatarsophalangeal joint deformity. None of these classically lead to skewfoot as a late sequela in the same way metatarsus adductus does.
