Greater trochanteric bursitis is a condition that occurs when the small fluid-filled sac (bursa) that covers the bony point of the hip bone (the greater trochanteric) becomes inflamed. This results in sharp, intense pain in the point of the hip that extends to the outside of the thigh. Overtime the pain may recede to an ache that spreads across a larger part of the hip. Often, the pain worsens when lying on the affected hip, rising from a chair after being seated for a prolonged period, walking for a long time, climbing a flight of stairs, and squatting. Greater trochanteric bursitis can affect men and women of all ages. However, it is more common in women and the elderly. Risk factors for developing greater trochanteric bursitis include repetitive stress on the hip, a hip injury, disease of the spine, leg length discrepancies, rheumatoid arthritis, surgery in the hip or a hip replacement, and calcium deposits. Most cases of greater trochanteric bursitis can be diagnosed through a physical examination, although imaging may be necessary to rule out other conditions. Treatment of greater trochanteric bursitis typically includes rehabilitative exercises and stretches designed to increase hip strength and flexibility. However, if symptoms persist or worsen, surgery to remove the bursa may be necessary.
