<qa>  What was the end point of the study reached?Complex regional pain syndrome was diagnosed when four of the following five symptoms were present throughout an area larger than the wrist, including the area distal to the wrist hand and fingers, and if they occurred or increased after activity: unexplained diffuse pain, which is not in normal relation to the fracture; difference in skin color relative to the other arm; diffuse edema; difference in skin temperature relative to the other arm; limited active range of motion, unrelated to the stage of fracture treatment. If CRPS was diagnosed, the end point of the study was reached and the protocol was terminated to enable treatment for CRPS.
