capsule of hip joint ( RID2646 )
I tried to inject her arthrogram under fluoro. Despite proper positioning, I felt like I was hitting hard leather, without definite needle on bone, and there was tremendous resistance to injection. I converted it to US guidance and injected without resistance. Arthro images in Obl Ax and Radial sequences show marked dark signal capsule thickening, which I believe is responsible for her symptoms. I wasnt sure if there was a small anterior labral tear. On MR you can see the trajectory of the needle avoided the thickend portion of the capsule. Have you seen this? Another reason I prefer US guided arthrography.
