Gluteus Medius arises from the superior
aspect of the external surface of the ilium, and attaches to the greater trochanter.
It acts primarily to abduct the thigh. The superior gluteal nerve innervates
the gluteus medius muscle.
Paralysis of the gluteus medius results in a gluteal gait characterized by waddling.
The pelvis falls toward the unaffected side when the opposite leg is raised
for each step.
