43F 18 years worsening hip pain referrered for evaluation of FAI

  1. It's not exactly "kosher" to use the CEA on tomographic imaging, but at the mid coronal plane, it measures 16 degrees and there's uncovering of the FH. Ax images through the mid FH are marked X at the center of the head, which lies lateral to the acetabular margins, because the acetabulum is developmentally shallow. This is DDH. This CANNOT be FAI, they are mutually exclusive----though there seems to be an inability to consider any other pathology. Oddly, the prescription included information that XRs (outside XRs) were reportedly Normal (hmmm). She has secondary DJD (blue arrow). Horrible degenerative labral tearing with cystic expansion of the anterior labrum. Also R Femoris (red), G Minimus (yellow) and Q Femoris (green) tendinosis without tear.

  2. Agree it’s DDH
    Check xrays if it’s anterosup, post sup or global dysplasia
    Looks global based on sector angles on mri
    The two conditions of ddh and fai in adults are not mutually exclusive though
    Check out our expert hip surgeon paper- Wells J et al
    Clinical findings and gait analysis reveal quiet a bit apart from alpha angles which are larger in adult hip dysplasia as well
