M76: Enthesopathies of lower limb, excluding foot
M76.0: Gluteal tendinitis
There are 3 gluteal muscles of different sizes. They connect the pelvis to the leg. They are used when stretching the leg backwards, for example. The gluteal muscles are also involved when you turn your leg.
An inflammation in the gluteal muscles can affect tendons, tendon sheaths, bursas or joint capsules. Tendons are made up of very firm connective tissue. Tendons attach muscles to bones. A tendon sheath is a covering for the tendon. It cushions the tendon and contains a small amount of fluid. This reduces friction between the tendon and its surroundings. A bursa is a cushion of connective tissue filled with fluid. For example, there is a bursa beneath tendons or between bones and skin. The bursa prevents the tissue from rubbing together. A bursa also enables pressure to be distributed better. Joints are encased in a joint capsule.
An inflammation can be caused by overwork, injuries or pathogens, for example. An inflammation may be painful. The pain may make moving your leg more difficult than usual.
