Clinical examination and classification systems of congenital clubfoot: a Narrative Review

Clinical examination of the newborn’s foot is a complex exercise that requires a lot of sensitivity, practice and deep understanding of normal and pathological anatomy, and the clinical assessment of a child with congenital talipes equinovarus, or congenital clubfoot, must be complete and it should not be limited to a simple orthopedic evaluation of the foot; the search for a cause is a pressing concern. This narrative review article aims to provide the key information about clinical examination of children with congenital clubfoot; classification systems are also described. Clinical examination of children with congenital clubfoot is essential. In particular, it is important to evaluate the mental age of the child (developmental milestones), to rule out the presence of a spinal dysraphism, to eliminate a mild form of neurological disease (congenital myopathy or arthrogryposis), as well as to carefully examine the face and hands of the patient. The examination of the foot and the classification of the clubfoot deformity complete the clinical evaluation. In the end, the pediatric orthopedic surgeon must not underestimate any clinical signs, and must act as a pediatrician. This narrative review summarizes the key points in taking a history and performing a comprehensive clinical examination for patients with CTVE; the review also briefly describes the normal foot anatomy and growth as to give the reader the opportunity to better understand the morphological and functional modifications secondary to congenital clubfoot.
