Through an open approach, the provider inserts an interlaminar stabilization or interspinous distraction, or decompression, device (IPD) and attaches it to the bony projections (spinous processes) on the back of adjacent vertebrae at one site in the lumbar spine to restrict painful motion (stabilize) or open up (distract) the neural foramina, relieving pressure on the nerve roots. The provider does not fuse (permanently join) the vertebrae.
