The risk profile of HVLA adjustments differs mainly because the anatomy and critical structures around C1-C2 are more vulnerable. The atlas–axis region (C1-C2) sits near the vertebral artery as it travels into the brainstem and near the spinal cord. A misapplied thrust here can affect the artery or the cord, so careful screening, assessment, and technique are essential, and many clinicians restrict or modify HVLA in this area when risk factors are present.

In the mid-cervical spine, the same general risks exist, but with joints that are more stable and with less direct involvement of the vertebral artery and the upper spinal cord. When the joints are stable and there are no red flags, HVLA in these levels tends to carry a lower risk profile.

So, the correct idea is that HVLA at C1-C2 carries a higher risk to critical structures and requires careful assessment and technique, while mid-cervical HVLA generally has a lower risk when stability is present. The other statements overgeneralize safety or contraindication and don’t align with the anatomy and clinical reality.
