Dr. Ebraheim’s educational animated video describes the transient osteoporosis of the hip.

It is an uncommon condition. The patient will experience a sudden onset of pain that intensifies with walking or other weight-bearing activities. The pain associated with transient osteoporosis will increase over time and may become disabling. There may be groin pain associated with the condition. Transient osteoporosis most often occurs in the hip joint but can also affect other joints such as the knee or the ankle. With transient osteoporosis of the hip, the femoral head loses density and strength.
It often occurs in middle-aged men and in women in the late stages of pregnancy (third trimester) or in the early postpartum period.
Radiography typically shows diffuse osteopenia and bone scan shows an increase uptake through the entire head and neck of the femur. X-rays and bone scan may be normal despite the hip pain. The x-ray will usually show that the joint space is spared. MRI will show complete replacement of th marrow on T1 and hyperintense marrow on T2 (intense bone marrow edema).
The symptoms may gradually subside and usually end in about 12 to 15 months, bone strength in the hip also returns to normal in the majority of people.
Differential diagnosis of transient osteoporosis in the hip.
1-Avascular necrosis: will be localized. Death of a segment of bone in the femoral head due to interruption of the blood supply. The femoral head may show a crescent shaped segment of dead bone. AVN usually occurs at the superior anterior aspect of the femoral head.
2-Metastatic bone disease
3-Femoral neck stress fracture
4-Infection
Transient osteoporosis involves the entire femoral head and neck. Avascular necrosis of the femoral head usually involves the superior anterior aspect of the femoral head.
Early differentiation from more aggressive conditions is important to avoid unnecessary treatment.
Treatment
•Partial weight-bearing crutches
•NSAIDS
•It is a self-limiting disease that is not a tumor, not an infection and not osteonecrosis.
