[Two-stage reposition and fixation of spondyloptosis with Harrington instrumentation and anterior intercorporal spondylodesis (author's transl)].

On the basis of 3 cases of true spondyloptosis, a two-step operation for repositioning and stabilisation using Harrington's instrumentation with anterior intercorporeal spine fusion is recommended. The first operation involves repositioning with the help of Harrington's rod through a dorsal approach. Approximately 2 weeks later, the distraction is increased by tightening the rod again. Reposition is then completed through an anterior transabdominal approach and an intercorporeal lumbar sacral fusion performed.
