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
David Roentgen Gotha, exhibited at Callenberg Castle in Coburg, north Bavaria. In 2012 Wolfam Koepp of the Metropolitan Museum of Art discovered a particular type of Roentgen table with removable legs for easier transport. Was this table the earliest form of flatpack? A team from the Victoria and Albert Museum investigated further and confirmed Koepp's process and conclusions in March 2014, shedding new light on the inventor of flat-pack / ready-to-assemble furniture. Until then, Gillis Lundgren held that title from 1951 for IKEA. Its blame has now been traced back 200 years before the pretender. David Roentgen not only mastered intrigue but
