Begin this core exercise lying on your back as demonstrated (figure 4). Slowly pull your belly button in, “away from your belt line”, and breathe normally. Your rib cage should remain relaxed and should not elevate during this process. You should be able to feel the muscle contracting if you press deeply 2cm in from the bony prominence at the front of your pelvis (figure 4). Practise holding this muscle at one third of a maximal contraction for as long as possible during everyday activities (. when walking etc.) provided it is pain free.
In extreme cases, where the pain does not improve after physical therapy, cortisone shots, and anti-inflammatory medication, the inflamed bursa can be removed surgically. The procedure is known as a bursectomy . Tears in the muscles may also be repaired, and loose material from arthritic degeneration of the hip removed.  (At the time of bursal surgery, a very close examination of the gluteal tendons will reveal sometimes subtle and sometimes very obvious degeneration and detachment of the gluteal tendons. If this detachment is not repaired, removal of the bursa alone will make little or no difference to the symptoms. [ citation needed ] )
Trochanteric bursitis can be caused by an acute injury, prolonged pressure on a bursa, or activities that require repeated twisting or rapid joint movement (such as jogging or bicycling long distances). These activities may lead to irritation or inflammation within the bursa. Trochanteric bursitis may occur together with disc disease of the low back or arthritis of the hip. It also may develop at the site of a previous hip surgery or occur along with iliotibial band syndrome . Conditions such as gout may also increase the risk for bursitis.
