Greater trochanteric pain syndrome
Tendinosis of the hip abductors / bursitis trochanterica
Pain on the outside of the hip that occurs while walking is a typical symptom of greater trochanteric pain syndrome. The pain is experienced around the hard lump located on the outside of the hip.
In women, the condition is seen primarily in the middle-aged or older. Men in other age groups may also be affected.
Description of condition
The iliotibial band is a large band of connective tissue (fascia) that runs from the pelvic ridge down the outside of the upper leg to the knee. It passes the greater trochanter along the way. This is a lump on the thigh that protrudes outward. The pain is caused by damaged or irritated structures that move over or along the greater trochanter.
The muscles located on the outside of the hip are called the hip abductors. They raise the thigh outward and prevent the hip joint from collapsing when we walk.
There are two muscles that attach to the iliotibial band which originate from the pelvis. These are the gluteus maximus and the tensor fasciae latae. The gluteus medius and the gluteus minimus are two other muscles that are located below the first two muscles;. These muscles run from the pelvis to the greater trochanter, where they attach. The vastus lateralis also attaches to the greater trochanter, which runs from there to the knee.
All these structures move directly over each other. Each muscle is surrounded by bursae to prevent friction. Bursae are like smooth fluid-filled cushions that prevent bones and tendons from rubbing against each other.
The pain that occurs with the greater trochanter pain syndrome is the result of various injuries to the structures described above. Greater trochanter pain syndrome is a collective term for the symptoms that are caused around the greater trochanter.
Cause and history
The symptoms can develop either gradually or acutely. There are various causes of greater trochanter pain syndrome.
- Tendinosis of the hip abductors: the tendon structure of the muscles decreases in quality.
- Partial ruptures (tears) of the hip abductors.
- Calcification of the attachment of the tendons surrounding the greater trochanter.
- Excessive friction of the iliotibial band over the greater trochanter (snapping hip).
- Sometimes the bursae may also be inflamed (this is more commonly known as "bursitis trochanterica" and is rarely an isolated event).
Signs & symptoms
Pain is felt on the outside of the hip, around the hard lump that can be felt here (the greater trochanter). The pain is felt when walking and when you press on the greater trochanter. This may also cause the patient pain at night, when he/she lies on the affected side. The pain radiates over the outside of the upper thigh down toward the knee.
The hip abductors may be weakened, resulting in the patient "waddling", with the trunk leaning over the affected side (Trendelenburg's sign). Standing on the affected leg may provoke the symptoms, sometimes after even as little as 30 seconds.
Physiotherapy may provide relief, if relative rest and reducing the strain on the affected leg does not ease the symptoms. The treatment consists of excentrically applied muscle strengthening of the hip abductors.
Other treatment forms include pain medication, providing shoe inserts (if legs are of differing lengths) and a corticosteroid injection. A corticosteroid injection may be very effective, but can be counter-productive in the long run.
