Specific to the lumbar, we can find four distinct intertransverse fibers. The three internal: intermamillian (red), mamillo-styloidian (orange), inter-styloidian (green); and for the external: intercostiform (purple). Between these fibers there is passage of the dorsal ramus nerves. Because the axis of the lumbar zygapophyseal joints are perpendicular to the direction of these nerves, a small lesion in this direction (i.e muscle spasm or misalignment of the vertebra) accentuates the tensioning of the aforementioned tissues and creates a shearing effect, which can cause back pain. Normalization of these muscles via 2TLS (transversal tendinous ligamentous stretching) can be particularly painful. Pain associated with this lesion in the lumbar can be more pronounced at the T12-L1 level, for example with Maigne’s Syndrome, due to T12’s unique characteristics. See post for more info on this.
