Clubfoot is one of the most common birth defects, with a prevalence in Europe estimated between 1 and 4.5 for 1000 live birth.

It is useful to distinguish the forms of isolated clubfoot, and the forms related to others morphological abnormalities (complex clubfoot). For the complex forms, the clubfoot can be integrated in a syndromic association, be the consequence of a serious harm of the central nervous system, be associate to a genetic musculo-skeletal disease or wether be associated to a karyotype abnormality.

In those cases, the prognosis depends more about the associated morphological abnormalities that can be the beginning of a severe disability or incompatible with life or any anomaly of the karyotype that clubfoot itself.

In case of several morphological abnormalities, to propose invasive samples with realization of a karyotype and chromosome analysis with CGH array is a consensual attitude.

What the investigators should recommended to the parents in case of isolated form is less obvious and the question of antenatal investigations can not be answered clearly in the literature. Thus, the management of these patients may vary from one CPDP to another.

This study project will make it possible to analyze the management offered to patients whose fetuses have club feet and to study the results of the various examinations carried out in order to adapt the prenatal counselling and to define the best diagnostic strategy to propose to the future parents.
