[Epiphysiodesis as a means of controlling growth (calculation of angle function for planning the correction of axis...

At the Orthopedic clinic of the university of Vienna epiphysiodeses have been used for treatment of leg-length-discrepancies and varus and valgus malformation. A physiological state was achieved in twelve joints out of 24 operated in sixteen patients. Bone age was to advanced in some of the other cases, while the staples were removed too late in the rest. We found the exclusive use of the growth prognosis for planning of the surgical procedure to be extremely difficult, which is why we now use fixed parameters (epiphyseal distance and growth prognosis) to define the ctg for exact mathematical evaluation. Not the surgical procedure is the problem in epiphysiodeses but planning of the operation.
