[A one-stager procedure in operative treatment of spondylolistheses: dorsal traction-reposition and anterior fusion (author's transl)].

On account of 41 cases of spondylolisthesis a one-stage operation for repositioning and stabilisation using Harrington's instrumentation with anterior intercorporal spine fusion is recommended. The advantage of this procedure is a secure fusion and a short hospitalisation. After 6 months the patient usually is rehabilitated.
