Primary Outcome Measures

Name	Time	Method
<p>The aim is to gain basic dynamic information (motion patterns) of the carpal<br /><br>bones of the proximal and distal row in patients with scaphoid nonunion. We<br /><br>specifically test the hypothesis that the fracture location with respect to the<br /><br>scaphoid apex is related to the kinematic pattern. Because anatomic variance of<br /><br>the insertion of the dorsal intercarpal ligament is known, this study compares<br /><br>the fractured wrist with the contralateral unharmed side in the same<br /><br>individual.<br /><br>We expect to detect abnormal motion patterns, which we will quantify in<br /><br>measurable values (3 translations and 3 rotations of carpal bones during motion<br /><br>of the hand). Delineation of specific motion patterns and discriminative values<br /><br>of dynamic information of the carpal bones will enable us to set up new<br /><br>definitions for diagnosing scaphoid nonunion wrist pathologies. </p><br>

Secondary Outcome Measures

Name	Time	Method
<p>1. The aim of rescanning patients with scaphoid nonunion after a reconstructive<br /><br>procedure is to investigate if these procedures have benefits for the wrist<br /><br>kinematics.<br /><br>2. The aim by using the MHQ questionnaire before and after treatment is to<br /><br>evaluate if there is a correlation between the pathological kinematical pattern<br /><br>and the patient complaints. </p><br>
