Primary Outcome Measures

Name	Time	Method
<p>The main study parameters will be the range of motion (ROM, pro-sup and<br /><br>flex-ext), grip strength, patient reported outcome measures (PROM), the<br /><br>position of the radius with respect to the ulna and the position of the axis of<br /><br>rotation. The latter two will act as independent variables in a linear<br /><br>regression to find out if and how they influence the first four parameters. The<br /><br>main study endpoint will be to optimize implant characteristics (size,<br /><br>placement, kinematic behavior) to improve wrist function.</p><br>
