Abstract:
Transient osteoporosis of the hip is an uncommon bone marrow oedema syndrome of unknown pathophysiology affecting previously healthy pregnant women and young to middle-aged men. The disorder is characterised by hip pain, reduced mobility, and the risk of fracture, which is significantly higher in pregnant than in non-pregnant individuals. Diagnosis is by magnetic resonance imaging. Other than a single case-control study, published literature is limited to case series and case reports, with no evidence to guide management, risk of fracture, mode of delivery, safety of breastfeeding and risk of recurrence. An international pregnancy registry may be useful to try to answer some of these questions.

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...
