Gluteus Medius Anatomy & Injections

The gluteus medius muscle is partially covered, on its lower-third part, by the gluteus maximus muscle. This makes up what is commonly referred to as the buttocks. The gluteus medius works to provide rotation of the thigh outward from the center of the body, which enables a steady walking gait.

The gluteus medius attaches to the leg at the top of the femur (thigh bone), close to the hip joint, on a bony prominence called the greater trochanter. The greater trochanter is a ridge on the femur (thighbone). The muscle attaches at the other end to the ilium, which is part of the big pelvic bone.

Weakness in the muscle, nerve damage, or problems with the muscle (or structures where it is attached) can cause a limp to develop, such as the Trendelenburg gait. This is an abnormal walking form where a person’s hip drops on the side opposite the damage or weakness, giving their gait a hobbled appearance.

The greater trochanter of the femur, where the gluteus medius muscle attaches, has a bursa sac of fluid that normally protects the bony protrusion. It can become inflamed and cause pain in the hip area, causing a condition known as trochanteric bursitis. Treatment of inflammation in this area usually involves stretching, anti-inflammatory drugs, and cortisone injections.


Carefully remove the injection supplies that have been provided by DP Injectables. Place the correct vial and injection supplies on a clean dry surface. This should include the vial, alcohol prep pads, IM syringe with needle, and bandaid. Wash hands and the area to be injected well. Dry hands and injection site with a clean dry cloth. Carefully remove the top of vial, or if using a multiple use vial, wipe the alcohol prep pad to clean the rubber top of the vial. Remove the needle cap. Hold the vial in one hand, and carefully push needle into rubber top. Turn vial upside down and pull syringe plunger until the correct amount of solution is in the syringe (1 ml). . Open the second alcohol prep pad, and clean the area to be injected well. Carefully thrust the syringe with IM needle into the muscle at a 90 degree angle.

Holding the syringe with one hand, gently pull back on the plunger. If no blood enters the syringe, then it is safe to inject the solution. If a flash of blood is seen, then the needle may be in a small vein. Retry positioning in this case. Inject slowly and steadily until desired amount has been given. Remove needle, carefully recap the needle and discard into waste container. Place bandaid over injection site.
