Percutaneous disc decompression in the management of chronic low back pain.

Although there has not yet been a percutaneous intradiscal procedure developed with the superior therapeutic efficacy of open surgery, these procedures are less invasive and avoid the complications of open surgery. All of these procedures have limitations, but their therapeutic effect increases substantially given careful patient selection and proper technique. New appliances and techniques to treat LBP or sciatica continue to evolve, and numerous controlled studies are underway. With tremendous technologic advances, use of minimally invasive techniques to treat chronic back pain continues to expand.
