Adduction sign in pediatric hip arthrography.

Various techniques for improving the success of needle placement in hip arthrography have been described. The authors describe a simple consistent sign that occurs in both subluxated and dislocated hips and is present only when the needle is correctly placed within the hip joint. This, in conjunction with other techniques, has improved their quality of hip arthrography.
