Figure 13.

Partial osseous avulsion of the gluteal muscles at the greater trochanter in a 59-year-old man who presented with the right hip pain without a history of trauma. Lauenstein view and anteroposterior and radiographs (not shown) did not show an obvious fracture line or disruption of bony contours in the acetabulum or the right femoral neck. (a) Coronal T1-weighted MRI displays an incomplete fracture line extending partially from the greater trochanter (arrow). (b) Coronal short tau inversion recovery MRI shows heterogeneous hyperintensity in the same region (arrow) as well as hyperintensity within the gluteus medius and minimus muscles (arrowheads) consistent with tissue edema and hematoma.
