Computerized tomography with routine arthrography in early evaluation of congenital hip dysplasia.

The earliest accurate assessment of the pathologic anatomy in congenital hip dysplasia allows for the most effective treatment and ultimate joint development. Computerized tomography has been suggested to better delineate bony orientation, size, and congruity; however, the inability of the routine CT scan to clearly depict cartilaginous structures has further confirmed the adequacy of the arthrogram alone in most patients. We present a technique employing computerized tomography following routine arthrography to more thoroughly assess the cartilaginous and soft tissue structures in the younger patient. Although certainly not indicated in all patients, this technique provides an effective diagnostic adjunct in select patients with complicated hip dysplasia early in the hip development.
