Kimura et al[3]	64, F	C4-C5, C6-C7	Intermittent spinal cordcompression
Rebai et al[5]	70, M	Not specified	A purely extradural decompression could be sufficient to induce regression of the medullary cavitation.
Lucci et al[6]	56, M	C4	The bony prominence produces ischemia and thus causes the degeneration of ascending and descending nervous fibers

Kameyama et al[8]	59, M	C3-C4 at C6-C7	The symptoms of the upper limbs improved after immobilization of the neck
