INTRODUCTION: Obstetrical separation of the proximal femoral epiphysis at birth is rare. Most of these fractures are associated with complicated deliveries. MATERIAL AND METHODS: Our patient was admitted on the first day after birth. He was born by caesarean section due to a breech presentation. The clinical examination revealed << pseudoparalysis >> of the left lower extremity. Laboratory studies were within normal limits. RESULTS: Roetgenograms showed a superolateral displacement of the proximal femur with normal acetabular development. An ultrasound examination revealed a normal position for the left femoral head within the acetabulum and no joint effusion. This excluded the possible diagnosis of septic or congenital dislocation of the hip and confirmed the diagnosis of traumatic epiphyseal separation. CONCLUSION: Recognition of this rare injury by using ultrasound may allow early diagnosis and treatment, thus preventing permanent deformities.
