Primary Outcome Measures

Name	Time	Method
<p>The aim is to estimate the motion of the distal fragment relative to the<br /><br>proximal fragment expressed in two parameters (rotation and translation). For<br /><br>these experiments the apparent changes in position of the fragments with<br /><br>respect to each other are displayed as a rotation around a Helical Axis of<br /><br>Motion (HAM)28 and translations along the HAM. The HAM notation therefore<br /><br>reduces the standard motion parameters (3 translations and 3 rotations) to one<br /><br>rotation and one translation. We will define the mean (µ) and standard<br /><br>deviation (*) of the displaced group and non-displaced group. </p><br>
