[The anatomical x-ray validation of microsurgical treatment methods in intervertebral hernias of the lumbosacral spine].

The microsurgical anatomy of the lateral region of the lumbosacral region of the vertebral canal was studied in 15 human cadavers. The vertebral canal and intervertebral foramina were X-ray studied in 10 healthy subjects and in 50 patients with lumbar osteochondrosis. The morphological and X-ray findings were used in the development of microsurgical methods for removing lumbar discal hernias, which were employed in 40 patients with this abnormality. The control group included 50 patients with discal hernias who had been operated on by the conventional methods. The advantages of microsurgical methods have been indicated.
