Abstract:
We report four cases of transient hip osteoporosis studied between 1995 and 1997. All patients were men. The diagnosis was based on clinical symptoms, absence of abnormal laboratory tests, increased uptake in the femoral head and neck on Tc-99 bone scans and magnetic resonance imaging showing Oedema of the bone marrow. In three patients radiographs showed osteopenia of the head and neck of the involved femur, whereas no major radiographic changes were seen in the fourth patient. The clinical symptoms lasted 7 months and there was no recurrence after 8-24 months' follow-up.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
