Greater Trochanteric Bursitis
Your body has more than 150 small, fluid-filled sacs called bursae. Some act as cushions between your bones and your tendons and muscles. They keep your tendons and muscles from rubbing on your bones as you use your joints. Bursitis results when a bursa becomes inflamed and swells with fluid.

Inflammation of one of the bursae in the outside of your hip, called trochanteric bursitis, is the most common form of bursitis of the hip.

Bursitis of the hip can result from a traumatic injury to your hip, but more often it's caused by repeated physical activity. Overuse of the muscles in your hip can strain them, along with attached tendons and tissues. Muscles and tendons may not move smoothly over a bursa, causing it to inflame and swell.

Excessive or prolonged pressure on your hips, such as from standing for a long time, can also lead to bursitis. In addition, bursitis can result from abnormal hip "mechanics" due to arthritis, a tight iliotibial band, a difference in the length of your legs or back problems.

There are many causes of greater trochanteric bursitis but since usually they are caused by abnormal biomechanics, we can effectively treat this condition with orthotics.  A custom orthotic will maintain proper biomechanics of the foot and lower leg which affects everything up the biokinetic chain.
