Percutaneous laser disc decompression (PLDD) is a minimally invasive therapy used to treat certain herniated discs. In this case, minimally invasive means that the procedure is characterized by a simple puncture and takes place under local anesthesia, which means the patient - in contrast to an 'open' back surgery - avoids a general anesthesia. Hospitalization and rehabilitation time decrease significantly. The PLDD is a particularly low-risk method, since the spinal canal does not have to be opened and the surrounding tissue is not damaged or removed. The decompression of the disc by laser is a decades-long (first time 1987) proven method that has been constantly evolving.
