Abstract
The number of surgical interventions on the lumbar spine is constantly growing due to the emergence of new surgical techniques aimed at treatment of degenerative spine pathology and a large number of patients, suffering from the back pain. Quite often, surgical intervention turns to be not effective enough and the pain syndrome persists, leading to the necessity for the repeated revision surgeries with the use of stabilizing systems. The review represents research data on the causes of recurrent-remitting course of degenerative process, problems of epidural adhesion as one of the back pain syndrome predictors, the survey of various stabilization systems and operative approaches for their implantation. The disadvantages and advantages of ventral approach with the use of interbody fusion are summarized in comparison with dorsal approach used for the installation of the transpedicular system and interbody fusion with a bone graft.
The positive features of interbody fusion from anterior retroperitoneal approach include the ability to quickly and completely remove the entire disc, decompress the dural sac without entering the vertebral canal, optimally select an implant corresponding to the size of the vertebral end plates, creation of the optimal lordosis angle, and provision of the shortest approach to the operated disk and to the place of neural structures compression.
The advantages of the dorsal approach with transpedicular system implantation and interbody fusion with a bone graft are better visualization of neural structures in comparison with discectomy from the ventral approach, the possibility of wide decompression and expansion of the extent of operation, the possibility of ablation of the facet joints by diathermocoagulation after the surgical wound was made, the reliability of posterior fixation, and familial approaches for a neurosurgeon with a lesser duration of training.
