Transient osteoporosis of the hip causes temporary bone loss in the upper portion of the thighbone (femur). People with transient osteoporosis feel pain immediately but symptoms usually go away within 6 to 12 months and the bone strength in the hip returns to normal.
Although transient osteoporosis sounds similar to age-related osteoporosis they are very different. Age-related osteoporosis is a painless condition that weakens the bones overtime and can put people at a greater risk for fractures throughout the body. It’s important to note that transient osteoporosis of the hip is extremely rare.
The hip is your body’s largest weight-bearing joint. This joint is also called a ball-and-socket joint. The ball is the upper end of the thighbone (femur), which fits into the socket (or acetabulum) at your pelvis.
Several muscles cross the hip joint and a strong capsule envelops the hip joint itself. Muscles are connected to bones that make up the hip joint by tendons, which are made from strong fibrous tissue, enabling motion of the joint.
What is it?
In transient osteoporosis of the hip, the femoral head loses density and strength.
Although there is not definitive cause for osteoporosis of the hip, some researchers have linked hormonal changes, abnormal stresses on the hip joint and obstruction of some blood vessels around the hip to the condition.
- Men between the ages of 30 and 60
- Women in the last three months of pregnancy or early post-partum
- Sudden onset of pain that intensifies with walking
- Pain increases overtime and becomes disabling
- Limited motion
- Noticeable limp
To determine whether you have transient osteoporosis of the hip your physician will ask you for a complete medical history, have you describe your symptoms and conduct a physical examination. An X-ray or MRI may be necessary to confirm the diagnosis and determine if there are other problems.
Transient osteoporosis generally resolves on its own in 6 to 12 months. Treatment options focus on reducing pain and maintaining strength. Options include:
- Activity minimization such as switching from high impact activity to low impact activity
- Physical therapy
- Assistive devices such as a cane
- Medications, the mainstays of medication therapy are the NSAID’s (non-steroidal anti-inflammatories) such as ibuprofen. Tylenol can also be effective.
