A case report of congenital bilateral proximal radioulnar synostosis in a 22‑month‑old child

Congenital radioulnar synostosis is a skeletal abnormality present at birth which may appear clinically as a mild abnormality in the early years. The diagnosis is usually delayed until functional abnormality is noticed. This is a typical case of congenital bilateral proximal radioulnar synostosis diagnosed at about 2 years despite mild upper limb abnormality noticed at birth. The rarity of this condition prompted the report of this case.
