Why the study?
Do arthrogram findings correlate with surgical findings in children with congenital dislocation of the hip?
Do arthrogram findings correlate with surgical findings in children with congenital dislocation of the hip?
In children with congenital dislocation of the hip, there is a significantly high acetabular index and floor thickness secondary to the absence of the femoral head.

Arthrogram acetabular measurements warrant cautious interpretation in dislocated hips; leaves open reliable correlation with surgical findings pending prospective studies.
The arthrogram plays an important role in the diagnosis and treatment of congenital dislocation of the hip (CDH), because congrous reduction has been related with hip outcome. We have reviewed 29 children younger than 1 year of age (34 hips) diagnosed and treated in our hospital for CDH, and we have recorded three radiologic parameters: acetabular index, acetabular floor thickness, and grade of dislocation. We also have evaluated three surgical and arthrogram findings (limbus, ligamentun teres, and transverse ligament) in order to study their statistical correlation, and consequently, to evaluate arthrogram usefulness. Results show a significantly high acetabular index and floor thickness as secondary to absence of femoral head.
