What is the most effective method to close the foramen in the cervical spine?

The most effective method to close the foramen in the cervical spine is through extension accompanied by ipsilateral side bending and rotation. This technique works by increasing the narrowing of the intervertebral foramen, effectively reducing the space within which the spinal nerve roots and other structures reside.

During extension, the cervical spine curves backwards, which impacts the position of the vertebrae effectively. Ipsilateral side bending (bending towards the same side) and rotation further facilitate this closing action by adding to the compression on the foramen from the same side, which can help alleviate conditions like radiculopathy by decreasing the size of the foraminal space where nerve roots exit. Therefore, this method is particularly useful in therapeutic settings aimed at addressing issues related to nerve impingement or similar pathologies affecting the cervical spine.

In contrast, other methods involving flexion generally increase the size of the foraminal space, which may not be beneficial for conditions requiring decompression. Similarly, utilizing contralateral movements (as seen in options involving contralateral side bending or contralateral rotation) creates a different mechanical advantage that does not facilitate foramen closure as effectively as ipsilateral movements.
