What Is Secondary Hyperparathyroidism? Secondary hyperparathyroidism is a parathyroid disorder resulting from hypocalcemia (low blood calcium level) that is characterized by excessive production of parathyroid hormone in the attempt to normalize the low blood calcium by releasing calcium from bone. ...

What Is Osteopenia In Childhood? Osteopenia is a metabolic bone disorder characterized by diminished bone mass with the retention of normal cell appearance and high bone turnover. That is, bone production does not keep up with bone loss. Bones looks ...

What Is Osteonecrosis? Osteonecrosis is a bone disorder resulting from insufficient blood flow to a part of the skeleton and is characterized by resulting death of bone cells (necrosis). After a while the bone can collapse. If this condition is ...

What Is Osteomalacia?
