Transient osteoporosis of the hip in pregnancy
Abstract:
A patient is presented with transient osteoporosis of the hip occurring in the third trimester of pregnancy. This syndrome is characterized by hip pain, limited motion, and osteoporosis of the femoral head with preservation of the joint space. The syndrome is self-limited with full recovery in three months to one year. Treatment is symptomatic with bedrest, protected weight-bearing, and analgesics as needed.

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...
