Transient Osteoporosis of the Hip

Transient osteoporosis of the hip is a sudden bone loss in the upper portion of the thigh bone, the ball that fits into the socket of the pelvis to form the hip joint. When this type of osteoporosis occurs, the bone loses density and is at greater risk for breaking.

Causes

The exact cause of transient osteoporosis of the hip is still unknown. Some researchers suspect it is related to limited blood circulation in the hip. It may also be due to hormonal changes or excessive stress on the bone.

Symptoms

Transient osteoporosis of the hip usually starts with sudden pain in the front of the thigh, the groin, or at the side of the hip. Pain will intensify with use and may result in some loss of motion. Many patients notice a limp when walking.

Diagnosis

Physicians will discuss symptoms, assess medical history, and perform a physical exam. Physicians will look for factors such as pain and the ability to move the leg in multiple directions in order to diagnose transient osteoporosis of the hip. X-rays may be used to identify a decrease in bone density.

Treatment

Transient osteoporosis of the hip usually resolves on its own within six months to a year. In order to manage pain and regain strength, anti-inflammatory medicines, walking aids, physical therapy, and nutrition guidance may be used.
