, orthopedic and other medical disciplines. RODIA provides two major functionality areas i.e. image quantitative evaluation and fracture healing monitoring. RODIA methodology allows to perform a quantitative evaluation of the medical images (e.g. X-ray, ultrasonography), enhancing bone fracture detection, fracture healing

Nonunion

Nonunion is permanent failure of healing following a broken bone.Nonunion is a serious complication of a fracture and may occur when the fracture moves too much, has a poor blood supply or gets infected. Patients who smoke have a higher incidence of nonunion. The normal process of bone healing is...
