Primary Outcome Measures

Name	Time	Method
<p>As an uninjured radius normally rotates +/- 180 degrees around the ulna at the<br /><br>distal radioulnar joint (DRUJ), the aim is to estimate the pattern of<br /><br>restricted motion of the posttraumatic (malunited) radius relative to the ulna,<br /><br>expressed in rotation at the level of the DRUJ. The main endpoint is to study<br /><br>whether we can differentiate between osseous (impinged) versus non-osseous<br /><br>(non-impinged) motion patterns as origin of restricted forearm rotation.</p><br>

Secondary Outcome Measures

Name	Time	Method
<p>Based on the patterns in inter-relational radioulnar motion pattern, the<br /><br>secondary aim is to develop a 4D classification tool for posttraumatic<br /><br>impairment of the forearm and to assess its inter- and intra-observer<br /><br>reliability. Futhermore to assess physiological mechanics of the radioulnar<br /><br>joint and symmetry in motion patterns between two healthy forearms on 4D CT<br /><br>scans.</p><br>
