The study is designed to evaluate the use of electromagnetic tracking in multi plane femoral osteotomies, namely extension derotation osteotomies. The goal is to raise the precision of the surgical procedure in order to improve the outcome in short- and long term. All patients are examined with an instrumented 3D gait analysis pre- and one year postoperatively. The electromagnetic tracking system is evaluated against a base line CT or MRI scan serving as reference standard pre- and postoperatively.
