Limitations are existing considerable differences between left and right forearms, and that a healthy contralateral anatomy is required. We evaluated if a computer model, not relying on the contralateral anatomy, may replace the current method by predicting the pre\u2010traumatic healthy shape. A statistical shape model (SSM) was generated from a set of 59 CT scans of healthy forearms, encoding the normal anatomical variations. Three different configurations were simulated to predict the pre\u2010traumatic shape with the SSM (cross\u2010validation). In the first two, only the distal or proximal 50% of the radius were considered as pathological. In a third configuration, the entire radius was assumed to be pathological, only the ulna being intact. Corresponding experiments were performed with the ulna. Accuracy of the prediction was assessed by comparing the predicted bone with the healthy model. For the radius, mean rotation accuracy of the prediction between 2.9\u2009\u00b1\u20092.2\u00b0 and 4.0\u2009\u00b1\u20093.1\u00b0 in pronation\/supination, 0.4\u2009\u00b1\u20090.3\u00b0 and 0.6\u2009\u00b1\u20090.5\u00b0 in flexion\/extension, between 0.5\u2009\u00b1\u20090.3\u00b0 and 0.5\u2009\u00b1\u20090.4\u00b0 in radial\u2010\/ulnarduction. Mean translation accuracy along the same axes between 0.8\u2009\u00b1\u20090.7 and 1.0\u2009\u00b1\u20090.8\u2009mm, 0.5\u2009\u00b1\u20090.4 and 0.6\u2009\u00b1\u20090.4\u2009mm, 0.6\u2009\u00b1\u20090.4 and 0.6\u2009\u00b1\u20090.5\u2009mm, respectively. For the ulna, mean rotation accuracy between 2.4\u2009\u00b1\u20091.9\u00b0 and 4.7\u2009\u00b1\u20093.8\u00b0 in pronation\/supination, 0.3\u2009\u00b1\u20090.3\u00b0 and 0.8\u2009\u00b1\u20090.6\u00b0 in flexion\/extension, 0.3\u2009\u00b1\u20090.2\u00b0 and 0.7\u2009\u00b1\u20090.6\u00b0 in radial\u2010\/ulnarduction. Mean translation accuracy between 0.6\u2009\u00b1\u20090.4\u2009mm and 1.3\u2009\u00b1\u20090.9\u2009mm, 0.4\u2009\u00b1\u20090.4\u2009mm and 0.7\u2009\u00b1\u20090.5\u2009mm, 0.5\u2009\u00b1\u20090.4\u2009mm and 0.8\u2009\u00b1\u20090.6\u2009mm, respectively. This technique provided high accuracy, and may replace the current method, if validated in clinical studies. \u00a9 2017 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.
