Gluteus medius

The gluteus medius (also gluteus medius muscle, latin: musculus gluteus medius) is one of the gluteal muscles situated beneath the gluteus maximus.


The gluteus medius originates between the anterior and posterior gluteal lines of the ileum.


The gluteus medius inserts along with the gluteus minimus at the greater trochanter of the femur.


The main functions of the gluteus medius are to abduct and internally rotate the hip. The contractions of the anterior fibers of the gluteus medius muscle result into flexion and internal rotation, but the contractions of the posterior fibers result into external rotation of the hip.


The gluteus medius is innervated by the superior gluteal nerve from the sacral plexus.
