Researchers at Lund University in Sweden, in collaboration with colleagues in Dresden, Germany, have developed a way of combining a bone substitute and drugs to regenerate bone and heal severe fractures in the thigh or shin bone. The study, how to quit lexapro published in the research journal Science Advances, was conducted on rats, but the researchers think that the method in various combinations will soon be commonplace in clinical settings.

“The drugs and materials we used in the study for the regeneration of bone are already approved. We simply packaged them in a new combination. Therefore, there are no real obstacles to already using the method in clinical studies for certain major bone defects that are difficult to resolve in patients. But we want to introduce the technique in a controlled form via clinical studies and have recently been granted ethical approval,” says Deepak Raina, orthopedics researcher and the lead author of the study.

Bones in the human body have a fantastic ability to repair injury, but some defects are so large or complicated that the healing process is delayed or absent. This may be due to the bone having been subjected to a major trauma in connection with a traffic accident for example, or a tumor or infection causing a major bone defect. These cases are currently treated through bone transplantation, usually with bone taken from the patient’s own pelvis.

“In cases involving severe open fractures in the lower leg, over 5 percent of all fractures fail to heal. With our method, we will be able to avoid taking bone from the pelvis, which is a major gain for the patient.”

There is a need for new solutions and several research teams, both in Europe and in the U.S., are working on improving the bone healing process. So far, the injectable cocktail successfully mixed by the Swedish and German researchers consists of three different components: an artificial ceramic material developed in Lund, a bioactive bone protein (rhBMP-2) and a drug, bisphosphonate, that combats bone resorption.
