Three-dimensional digital displays in congenital dislocation of the hip: preliminary experience.
Four patients with congenital dislocation of the hip (CDH) were studied on a research basis with three-dimensional computed tomography (3-D CT) or, alternatively, with three-dimensional magnetic resonance imaging (3-D MR). 3-D CT and 3-D MR proved useful in demonstrating the extent of anterior and posterior acetabular coverage. 3-D CT was limited to patients greater than 6 months of age with ossified femoral heads. 3-D MR, in contrast to 3-D CT, demonstrated the cartilaginous femoral head in children less than 6 months of age, while avoiding gonadal irradiation. Both 3-D CT and 3-D MR appear promising in confirming the diagnosis and facilitating the choice of treatment modality in the child with complicated CDH.
