what is trochanteric
Trochanteric bursitis. Trochanteric bursitis - also known as greater trochanteric pain syndrome - is a common hip syndrome that causes pain and tenderness at the bony, outside point of the hip, known as the greater trochanter. It happens when the sac of fluid (the trochanteric bursa), located between the hip and the muscles and tendons of the thighs, becomes inflamed.
