14 cases of various pathology of inferior lumbar spine treatment results were analyzed. The anterior interbody fusion has been performed at all patients using cylindrical titanium implant of container type. Retroperitoneal surgical approach to lumbar spine, spinal decompression and further stabilization were described in details. It was found out that proposed method of dural sack and neural roots decompression is more effective than posterior approach technique. Good functional outcome was achieved in all cases. The described method was recommended at spondilolystesis of I–II degree, large posteromedial hernias. The method is most effective at patients with recurrent posteromedial hernias with severe scarring of anterior extradural space.
