Lumbar Percutaneous Mechanical Disc Decompression

Description

Lumbar percutaneous mechanical decompression is a minimally invasive and highly effective treatment for low back pain caused by contained herniated discs and protruding discs. The procedure is designed to alleviate pressure on a compressed nerve by directly excising the disc that is compressing the nerve root. Decompression of the nerve root may restore functionality and alleviate pain in patients with low back pain.

Herniated discs press against the nerve, causing debilitating pain. During lumbar percutaneous mechanical disc decompression, a physician will remove a portion of the nucleus pulposus using a special medical device. This removes pressure from the nerve and relieves pain. Percutaneous mechanical disc decompression is considered minimally invasive and effective.

Indications

Indications for percutaneous mechanical disc decompression include the following:

  • Unilateral leg pain greater than back pain
  • Radicular symptoms in a specific dermatomal distribution that correlates with MRI findings
  • Positive straight leg raising test or positive bowstring sign, or both
  • Neurologic findings or radicular symptoms
  • No improvement after 6 weeks of conservative therapy
  • Imaging studies (CT, MRI, discography) indicating a subligamentous contained disc herniation
  • Well maintained disc height of 60%
