Percutaneous decompression of the nucleus pulposus of a herniated lumbar intervertebral disc is a minimally invasive procedure designed to alleviate pain and discomfort caused by a contained herniated disc. This procedure employs a needle-based technique to remove disc material, utilizing fluoroscopic imaging or other forms of indirect visualization to guide the process. The primary goal is to relieve pressure on the spinal nerves by removing bulging disc material that has not ruptured. Various methods can be employed during this procedure, including manual techniques, automated systems, and advanced technologies such as radiofrequency or laser applications. Each method involves the careful insertion of specialized instruments through a needle that is strategically placed between the vertebrae, allowing access to the center of the disc. Radiographic monitoring, particularly fluoroscopy, is crucial for ensuring accurate placement and guiding the removal of herniated tissue. Techniques such as laser ablation or coblation nucleoplasty are utilized to effectively vaporize or disintegrate the disc material, creating channels that further decompress the disc. This procedure can be performed at single or multiple lumbar levels, making it a versatile option for patients suffering from lumbar disc herniation.
