[The need for spongiosa grafting in thoracolumbar vertebral body fractures].

Report on examination of 31 patients with fractures of spine in thoracolumbar region. All patients were treated by external fixation without accomplishing a plastic of spongiosa. The permanent SI-Index after operation is coming to 0.85. The outcome by use of external fixation is attesting our opinion, that with this method a plastic of spongiosa isn't necessary.
