[Ventrale derotations-spondylodesis (author's transl)].

Results about 26 cases operated with the new developed "Ventrale Derotations-Spondylodesis". The first results with this new method are better than the results of the Harrington and the Dwyer method as it allows the operative derotation and lordosation. The risk of the operation put in relation to the distraction method by Harrington seems less. The importance of the operation one can't put into relation to the rather simple postoperative treatment. The results of the first 19 cases give the impression that the advantages of the Ventral Derotations-Spondylodesis make this method prefer to other instruments in the operative treatment of scoliosis.
