[Controlled arched osteotomy for the correction of malposition in healed fractures]

The guided arched osteotomy and the oscillating saws specially developed for this operation have proven to be a competent technique to correct malposition following fractures. Its essential advantage is that the equipment offers the possibility to perform an exact and protective cylindrical cut, which assures exact parallel, relatively large contact areas and hence a favourable postulate for the healing action. Moreover, the saddle-shaped contact area offers protection against unwanted rotation. Furthermore, the shortening of the bone is limited to the width of the very thin saw cut performed. An additional advantage is offered in the possibility to carry out further correction without the necessity of a repeated osteotomy, should the x-ray control show that the primary correction has not turned out satisfactorily.
