    Rupture of an intervertebral disc into the body of a vertebra?

    Does "Rupture of an intervertebral disc into the body of a vertebra" mean "when an intervertebral disc ruptures, it penetrates into the body of a vertebra"?

    Context:

    Chapter 77
    Intervertebral Discs and Radiculopathy
    Paul C. McCormick
    Rupture of an intervertebral disc into the body of a vertebra was first described by Schmorl in 1927. Earlier, in a 1909 text on neurologic surgery, Krause described operating on an iceman who had been diagnosed by Oppenheimer as suffering from a lesion localized to L-4. Krause found an extradural mass that was described pathologically as a chondroma; the operation apparently affected a cure. There were other reports of chondromas removed at explorations of the intervertebral area. It remained for Mixter and Barr in 1934 to point out that these lesions were actually fragments of intervertebral discs and that they were responsible for sciatica.

    Yes. Discs normally rupture out from between the discs, as in this video:
    Disc protrusion - YouTube
    But if the vertebra is pathological, the disk can actually rupture into the bone, as here:
    Schmorl's nodes - Wikipedia, the free encyclopedia

    Not disagreeing, of course - I know when I'm beat - but the OP asked
    Does "Rupture of an intervertebral disc into the body of a vertebra" mean "when an intervertebral disc ruptures, it penetrates into the body of a vertebra"?
    ...
    The answer to that is No. A thing/process was 'first described...'. A sentence was not described. The sentence provided - 'when an intervertebral disc ruptures, it penetrates into the body of a vertebra' - describes that thing/process; that's not the same as having the same meaning or being the same. It was on the right track, but it could have been worded more carefully.
