Tactics of surgical treatment of spondyloptosis including use of transpedicular external fixation device is presented. There were 4 patients with L5 spondyloptosis. The tactics is characterized by minor traumatization of lumbosacral spine with external fixation device, decrease of neurologic complications rate owing to gradual L5 reduction, possibility of spine deformity elimination, significant technical simplification of internal transpedicular osteosynthesis performance. Clinical results showed normalization of anatomic interrelation in lumbosacral spine, elimination of vertebroradicular conflict, restoration of trunk balance and anthropometric proportion as well as stabilization of L5-S1 segment by osteo-metalic block.
