Removal of the disc herniation causing the pressure of the nerve element (nerve root, cauda fibre) from the posterior, open, mini-excision (approx. 3-6 cm), release of the nerve element under anaesthesia – called microdiscectomy.
In the case of a hernia in the spinal canal and the root canal accessible from the root canal, the procedure is as follows:
During lumbar disc herniation surgery, we reach the spinal canal through a small incision, by gashing the fascia that is located in the middle, posterior zygapophysis of the vertebrae, by detaching the muscles, with the removal of the ligamentum flavum connecting the vertebral arches, and by removing minimal parts of the bone of the vertebra above the vertebral arch and the inferior articular process.
We lift the strained nerve root from the hernia. From the spinal canal, we take out the embossed or torn disc(s), thus releasing the pressed, strained nerve root and radicals. Damaged disc parts are removed from the inside of the disc as needed. If necessary, the bone-constricted spinal or root canal is dilated by removing the constricting bone elements. In the surgical area, a suction tube (drain) is left behind, and we close the wound above the drain.
