Gluteus Medius: Located partially underneath the gluteus maximus, the gluteus medius plays a key role in hip abduction (moving the leg away from the body) and stabilizing the pelvis during ...
When a person with paralysis of the superior gluteal nerve is asked to stand on one leg, the pelvis descends on the unsupported side, indicating that the gluteus medius on the contralateral side is weak or non-functional. This observation is referred to clinically as a positive Trendelenburg's sign. [1]
The gluteus medius, one of the three gluteal muscles, is a broad, thick, radiating muscle. It is situated on the outer surface of the pelvis . Its posterior third is covered by the gluteus maximus , its anterior two-thirds by the gluteal aponeurosis , which separates it from the superficial fascia and integument.
Trendelenburg's sign is found in people with weak or paralyzed abductor muscles of the hip, namely gluteus medius and gluteus minimus. [1] It is named after the German surgeon Friedrich Trendelenburg. It is often incorrectly referenced as the Trendelenburg test which is a test for vascular insufficiency in the lower extremities.
Gluteus minimus: The smallest of the three glute muscles and is located beneath the gluteus medius. It assists with hip abduction and rotation, and also contributes to the stability of your hip joint.

During the stance phase, or when standing on one leg, the weakened abductor muscles (gluteus medius and minimus) on the side of the supporting leg allow the opposite hip to droop. To compensate, the trunk lurches to the weakened side to maintain the center of gravity over the supporting leg. This produces a characteristic "waddling" gait.
The more common lateral extra-articular type of snapping hip syndrome occurs when the iliotibial band, tensor fasciae latae, or gluteus medius tendon slides back and forth across the greater trochanter. This normal action becomes a snapping hip syndrome when one of these connective tissue bands thickens and catches with motion.
