Gluteus Medius Muscle

Gluteus medeius Muscle Anatomy

Gluteus medius muscle is part of the three gluteal muscles, and is a broad, thick, radiating muscle, situated on the outer surface of the pelvis.

Origin:

Outer surface of the ilium, between the anterior and inferior gluteal lines, and the edge of the greater sciatic notch.

Insertion :

Anterior surface of the greater trochanter of the femur.

Nerve supply :

Superior gluteal nerve L4, L5, S1) .

Blood supply

The deep branch of superior gluteal artery. The tendon, mainly supplied by the trochanteric anastomosis. This anastomosis is formed between the ascending branch of the medial circumflex femoral artery and descending branches of the superior gluteal and inferior gluteal arteries.

Action

Abduction of the thigh, internal rotation of thigh.

Function

When the proximal attachment of gluteus medius is fixed, the muscle can contract as a whole or it can contract with its anterior fibers only. In the former case, the axis of the movement goes through the hip joint and muscle pulls the greater trochanter superiorly and abducts the thigh.

In the latter case, as the axis of the movement tilts anteriorly, the muscle causes the internal rotation of the thigh.

Gluteus medius muscle exercise

Gluteus medius muscle exercise mainly of 2 types

  • Gluteus medius muscle stretching exercise
  • Gluteus medius muscle strengthening exercise

Strengthening exercise:

Clamshell exercise

Lie on your side, with legs stacked and knees bent at a 45-degree angle.
Rest your head on your lower arm, and use your top arm to steady your frame. …
Engage your abdominals by pulling your belly button in, as this will help to stabilize your spine and pelvis.

  • Using a wall for balance, stand with one side of your body on a wall.
  • Cross your leg farthest from the wall in front of the other.
  • Place one hand on the wall and the other on your hip. Then lean your upper body away from the wall, and push your hip toward the wall.
  • Hold for 20 to 30 seconds, then repeat on the other side

Related pathology

A peripheral injury of the superior gluteal nerve may lead to loss of motor function. The classical sign is the pelvis dropping to the healthy side when standing on one leg (Trendelenburg’s sign). In order to maintain the balance, the patients compensatorily bend their upper body to the side of the stance leg. Furthermore, they walk with conspicuous sideward movements (Duchenne gait, also “waddling gait”).

When performing an intramuscular injection in the gluteal region, an injury of the sciatic nerve and superior gluteal nerve has to be avoided. Therefore, a recommended site of injection is the gluteus medius muscle in the upper outer quadrant of the buttock (Hochstetter’s technique).
