Bone marrow helps bones to repair themselves

Specially prepared titanium mesh and bone marrow cells have made it possible to allow new bone cells to grow in bone fractures. Researchers inserted a titanium mesh scaffold into a bone fracture in a rat. They allowed bone marrow cells to grow on this and the bone marrow cells stimulated new bone growth. In combination with bone marrow cells, titanium mesh forms a good culture medium for new bone growth in the case of bone damage. The researchers improved this bone growth by dynamically ‘sowing’ the cells onto the mesh.

COX-2 Inhibitors Interfere with Bone Growth, Healing

Researchers have found that selective COX-2 inhibitors ? a class of medications widely prescribed for painful inflammatory conditions such as osteoarthritis and rheumatoid arthritis – interfere with the healing process after a bone fracture or cementless joint implant surgery. Their findings suggest that patients who regularly take COX-2 inhibitors should switch to a different medication, such as acetaminophen or codeine derivatives, following a bone fracture or cementless implant.
