The images indicate that you have an old injury or severe degenerative disc at C6-7. This creates significant angulation at this level. The good news is that the spinal canal is still capacious in spite of this deformity. There might be some evidence of cord signal changes on one image but this has to be compared to the axial images of the same level to confirm this finding.
Even if there is cord signal change (and I am not sure of this), there is no evidence that the current anatomy of the cervical spine caused this problem. The spinal canal is large and there is no evidence of instability.
