ABC News reported last week on new clinical trial results that reveal impressive fracture-healing properties of a drug approved by the Food and Drug Administration seven years ago to treat osteoporosis.  Forteo, a synthetic form of a hormone (parathyroid) that exists naturally in the body, is injected once a day and works by activating idle stem cells in bones, so they turn into bone cells and start building more bone, more quickly. It increases bone density and bone strength and therefore can help prevent bone fractures in patients at higher risk for fractures such as those with osteoporosis. The latest clinical trial findings suggest that Forteo not only can strengthen bone and prevent fractures, but that it is able to significantly speed up the healing process and reduce pain in patients with hard-to-heal fractures.

Forteo works differently than the bisphosphonate medications (Fosamax, Actonel, et al.) that are frequently prescribed for the treatment of osteoporosis.  Bisphosphonates kill the cells that degrade bone to slow bone loss, while Forteo stimulates the cells that build bone to make bones larger and harder.

Avascular Necrosis/Osteonecrosis patients may find this story of interest as it relates to a medication that is said to have significant bone-building and bone-cell-regenerating properties, and therefore might be worthy of more investigation and discussion with one's physician.
