<unk>  (GTPS), also known as<unk>  bursitis, is inflammation of the<unk>  bursa, a part of the hip.
This bursa is at the top, outer side of the femur, between the insertion of the gluteus medius and gluteus minimus muscles into the<unk>  trochanter of the femur and the femoral shaft. It has the function, in common with other bursae, of working as a shock absorber and as a lubricant for the movement of the muscles adjacent to it.[citation needed]
Occasionally, this bursa can become inflamed and clinically<unk> ful and tender.  This condition can be a manifestation of an injury (often resulting from a twisting motion or from overuse), but sometimes arises for no obviously definable cause. The symptoms are<unk>  in the hip region on walking, and tenderness over the upper part of the femur, which may result in the inability to lie in comfort on the affected side.[citation needed]
More often the lateral hip<unk>  is caused by disease of the gluteal tendons that secondarily inflames the bursa.  This is most common in middle-aged women and is associated with a chronic and debilitating<unk>  which does not respond to conservative treatment. Other causes of<unk>  bursitis include uneven leg length, iliotibial band syndrome, and weakness of the hip abductor muscles.<unk>  can remain incorrectly diagnosed for years, because it shares the same pattern of<unk>  with many other musculoskeletal conditions. Thus people with this condition may be labeled malingerers, or may undergo many ineffective treatments due to misdiagnosis. It may also coexist with low back<unk> , arthritis, and obesity.
