Primary Outcome Measures

Name	Time	Method
<p>Difference in coronal Cobb angles after two year of follow-up. </p><br>

Secondary Outcome Measures

Name	Time	Method
<p>Is there a difference in<br /><br>• coronal Cobb angle correction direct postoperatively;<br /><br>• correction loss during (at least) two years of follow-up;<br /><br>• vertebral rotation correction;<br /><br>• complication and/or revision rate;<br /><br>• effects on pulmonary function;<br /><br>• postoperative lung volume;<br /><br>• cosmetic outcomes;<br /><br>• subjective questionnaire results (including patient*s satisfaction);<br /><br>between proximal pedicle screw fixation and proximal hook claw fixation?<br /><br><br /><br>- Is there a correlation between the extent of scoliosis correction and the<br /><br>degree of patient satisfaction?<br /><br>- How is the accuracy of thoracic pedicle screw placement?</p><br>
