Dynamic Roentgen stereophotogrammetry has proven valuable in the evaluation of fixation for hip and knee arthroplasty, as early RSA evaluations have shown high predictive value for later aseptic component loosening. In contrast, Dynamic RSA makes it possible to accurately assess both micro movements in the fixation interface and kinematics of the prosthetic components in three dimensions, during active motions. Dynamic Roentgen stereophotogrammetry Dynamic Roentgen stereophotogrammetry (also referred to as dynamic RSA) is a modern and sophisticated x-ray recording method, used to measure real-time 3D motions of prostheses and bones during motion with high accuracy. It is mostly used in orthopedic research settings and
Carl August Wilhelm Berends junger Ärzte am Krankenbett" (Education of Young Physicians at the Bedside), in which he described his experiences at the Thielschen Krankenhaus in Frankfurt. Shortly after his death in 1826, his one-time student, Karl Sundelin, published Berends' lectures on practical medical science (""Vorlesungen über die praktische Arzneiwissenschaft""). Carl August Wilhelm Berends Carl August Wilhelm Berends (April 19, 1759 – December 1, 1826) was a German physician born in Anklam, Pomerania. He studied medicine at Viadrina University in Frankfurt an der Oder, where in 1788 he became a professor of medicine. In 1811 he moved to the University of Breslau, being due
