Efficacy of using an air arthrogram for EUA and injection of the hip joint in adults.

Hip arthrography usually requires the injection of iodine based dyes which can cause complications. We wanted to determine the accuracy of using air for hip arthrography.A prospective study was undertaken including all adults who had a hip arthrogram. We initially did an air arthrogram and subsequently injected iohexol to see if we were still in the joint.Forty injections were done. Mean age 32 years. There was a 100% success rate with obtaining a positive air arthrogram.Air arthrogram of the hip offers a safe, cost free and accurate alternative to iodine based arthrograms.
