[Screening and diagnostic recommendations in the developmental dysplasia of the hip].

Developmental dysplasia of the hip (DDH) is a hip joint anomaly that is characterized by a laxity or abnormal positioning of the femoral head with respect to the acetabulum. It is the most common perinatal pathology of the skeleton and includes a spectrum of alterations ranging from flattening or acetabular dysplasia, to a complete dislocation of the femoral head outside the joint that can compromise joint development and stability. The purpose of this presentation is to transmit a systematic study in the evaluation of the newborn's hip, emphasizing a correct physical examination as primordial in the detection of DDH. Also, guide the pediatrician in the proper selection of the complementary diagnostic method to be used according to the age of the patient, in order to optimize detection and reduce the number of dislocated hips in early and late stages as well as the incidence of related pathologies.
