Postoperative computed tomographic evaluation of congenital hip dislocation.

The use of computed tomography (CT) in the postoperative evaluation of 19 congenitally dislocated hips is presented so that appropriate indications for reduction can be determined and radiologic criteria can be defined for judging whether reduction is satisfactory. The radiologic technique is presented. CT is an accurate and cost-effective modality that is capable of demonstrating subtle changes in femoral head position.
