ACETABULUM/LABRUM: No traumatic labral tear.
MUSCLES/TENDONS/LIGAMENTS: Diffuse swelling around the gluteus minimus as it approaches the anterior facet of the greater trochanter of the femur is noted. A cystic delamination tear involves the interstitium of the insertion best seen in the axial projection. Diffuse swelling anterior to it.
The mid to anterior fibers of the gluteus medius footprint on the middle facet but relatively sparing the superior facet are noted with associated inflammation, and peritendinous swelling.
Gluteus maximus insertion is normal. Posterior facet of the greater trochanter is normal.
The ligamentum teres, transverse acetabular ligament, and iliofemoral ligament are normal.
Adductors, hamstrings, hip flexors are normal.
