Discectomy is the removal of the nucleus pulposus that slipped out of the degenerated intervertebral disc and led to irreversible pressure on the nerve root. Nerve root decompression enables the restoration of muscle functions supplied by the compressed nervous structure (lifting of paresis). The endoscopic procedure is characterized by low invasiveness - it requires making one or two small holes (approx. 5 mm) on the back through which surgical instruments and a camera are inserted. There is no need to cut the muscles or bone elements of the spine. As a result, the patient's convalescence period is shorter compared to an open surgery.
