[Revalgisation after intertrochanteric varus osteotomy in infancy]

The causes for revalgisation after varus osteotomies are examined in 153 follow ups. Varus osteotomies which slow an insuffizient fixation due to faulty technic or use of Kirschner wires demonstrate only a slight degree of revalgisation. In contrast, stable fixation leads to post-operative revalgisation directly proportional to the time of rigid fixation, we therefore recommend the removal of the fixation device after osseous consolidation, i.e. after 6 months.
