Technique and Interpretation of Arthrogram for Developmental Dysplasia of the Hip

Closed reduction, arthrography and hip spica application is the treatment of choice for DDH between 6 and 18 months. There is a lot of controversy about what exactly constitutes an “acceptable” closed reduction and arthrogram and the arthrography findings are often difficult to interpret. In this video, the authors describe the technique to perform the arthrogram as well as the interpretation of the same. Various static parameters such as the femoral head coverage, the medial dye pool and the hourglass constriction are shown. In addition, the validity of the safe zone is discussed. With this video technique article, the authors hope that it becomes easy for the budding paediatric orthopaedic surgeon to perform and interpret the DDH arthrogram with ease.
