A discectomy is a surgical procedure performed to relieve pain and symptoms associated with a herniated or degenerated disc in the spine. It involves removing all or part of the damaged disc to alleviate pressure on the nerves and spinal cord. This can be done through open surgery or minimally invasive techniques. Discectomy aims to improve mobility, reduce pain, and prevent further damage. Rehabilitation and physical therapy are often recommended afterwards to aid in recovery and strengthen the affected area.
