Greater trochanteric pain syndrome

Greater trochanteric pain syndrome (GTPS) is a common hip condition that causes pain over the outside of your thigh or buttock muscle.

GTPS (previously called trochanteric bursitis) is due to small changes to the nearby muscles or tendons. GTPS often mimics pain generated from other sources, including degenerative joint conditions, i.e. osteoarthritis of the hip and spinal problems.

Between 20 and 30% of people with low back pain experience GTPS. It is more common in people over 40, and affects women more than men.
