M99.6: Osseous and subluxation stenosis of intervertebral foramina

Osseous and subluxation stenosis of the intervertebral foramina refers to a condition where the passageways located in the tiny bony canal in the spinal column (known as the intervertebral foramina) become narrow or constricted due to bone growth or subluxation, which is a partial dislocation. This can cause pressure on the spinal nerves that pass through these foramina, leading to symptoms such as pain, numbness, or even weakness in the arms or legs. This condition might occur due to various factors including aging, arthritis, or injury to the spine, and is commonly associated with conditions like osteoarthritis and rheumatoid arthritis. While it can affect any part of the spine, it is most often seen in the cervical (neck) or lumbar (lower back) regions. Progressively, if left unmanaged, this can lead to decreased function and quality of life due to pain and disability.
