Facets on greater trochanter: anterior (gluteus minimus), lateral , posterior and postrosuperior
Gluteus minimus attaches to anterior facet
Gluteus medius attaches to lateral and posterosuperior facets
Bursae: trochanteric bursa, subglutues minimus bursa, sub gluteus medius bursa
Pathology:
Tear in the abductor tendon
Abductor tendinopathy
Bursitis
MRI:
Increased T2 signal within the tendon
Partial or full thickness tear
