[First cases of using Cotrel-Dubousset instrumentation in Hungary].

In the treatment of scolioses of different origin the spondylodeses performed from a dorsal exposure have an outstanding role. For the fixation of the spine several instruments were constructed; one of them is the Cotrel-Dubousset Instrumentation used since 1983 by which it became possible, beside the spinal correction and fixation in three dimensions, the omission of the external fixation devices. Authors report on the first experiences in Hungary with the CDI system on five patients and state that from the numerous advantages of the CDI the expansion of correction possibilities, the development the physiological spinal curvatures, the correction in three dimensions and the omission of the external fixation are outstanding.
