FUSION OF AXIS WITH THIRD CERVICAL VERTEBRA

RECENTLY Cave (1937) reported on some sixty-two cases of fusion of the axis with the third cervical vertebra; he emphasized the normal limitation of movement between these bones, termed the third vertebra the "vertebra critica" and interpreted fusions of the axis with this vertebra as attempts at the formation of a functional cervical "sacrum". Borovansky (1928) discussed the same subject, and noted that the minimal spinal mobility obtaining between the second and third cervicals disposes towards their fusion, as evidenced in various mammals. The three specimens herein described reveal various phases of this particular variety of vertebral synostosis.
