(Medical Xpress)—Researchers at Charité – Universitätsmedizin Berlin have succeeded in demonstrating an association between delayed bone fracture healing and increased concentration of specific immune cells in the blood of the patient. Results of the study show that the adaptive immune system responds to the fracture in a similar way as to an infection and attempts to fight against it. The study appears in the current issue of the journal Science Translational Medicine. http://medicalxpress.com/news/2013-03-immune-bone-fractures.html Medical research Fri, 22 Mar 2013 09:22:17 EST news283162157 In a new study presented today at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), researchers reviewed existing literature on smoking and the healing of fractures involving long bones (bones that are longer than they are wide). http://medicalxpress.com/news/2013-03-affects-fracture.html Surgery Fri, 22 Mar 2013 01:00:01 EST news283106828 (Medical Xpress)—By studying the underlying differences in gene expression during healing after a bone break in young versus aged mice, Jaimo Ahn, MD, PhD, assistant professor of Orthopaedic Surgery at the Perelman School of Medicine, University of Pennsylvania, and his colleagues aim to find specific pathways of fracture healing in humans. The team of researchers will present their findings in a poster presentation beginning Tuesday, March 19, 2013 at the 2013 American Academy of Orthopedic Surgeons annual meeting in Chicago. http://medicalxpress.com/news/2013-03-differences-bone-mice-seniors.html Surgery Thu, 21 Mar 2013 08:09:55 EST news283072188 (HealthDay)—Denosumab does not appear to delay fracture healing or contribute to other complications when used to treat postmenopausal women with osteoporosis, according to research published in the Dec. 5 issue of The Journal of Bone & Joint Surgery. http://medicalxpress.com/news/2012-12-denosumab-nonvertebral-fracture.html Diseases, Conditions, Syndromes Wed, 19 Dec 2012 17:20:01 EST news275158618 Researchers at the University of North Carolina at Chapel Hill School of Medicine have shown in an animal study that transplantation of adult stem cells enriched with a bone-regenerating hormone can help mend bone fractures that are not healing properly. http://medicalxpress.com/news/2011-06-stem-cell-treatment-option-broken.html Medical research Sun, 05 Jun 2011 13:58:24 EST news226501077
