Looking at the bomechanics of the cervical spine is also highly effective in treating cervical dics herniations. Without getting in to the probable dysfunctions of the upper cervical spine (C0-C3) which always cause compensatory motions in the mid to lower c-spine, let us look at the typical pathological dysfunctions of C5-C6.
Typically what one will find on inspection is that C5 has sheared itself anterior on C6. This is evident on palpation, but also when asking the patient to extend his/her neck. On active neck extension one will not find segmental movement throughout the c-spine but rather you will see a hinging at the C5 level that we called 'Pez Head' (named after the Pez candies dispensers). This anterior displacement of C5 will bias the C5 disc posteriorly. Also, please keep in mind that the individual vertebral bodies are able to rotate upon eachother. So, another typical dysfucntion of C5 is that of being rotated either to the right or left coupled with side bending. Remember that vertebral rotation increases intradiscal pressure and will contribute to disc herniation as well as side bending which will bias a disc herniation to one side (i.e. side bending left will bias a disc herniation right).
Biomecnahics according to Fryette's Laws states that the typical cervical spine (C3-C7) has what is called Type II motion, in which mobility is depenedent upon thefacet joints, and dysfunctions will be rotated and side bent to the same side. Again in keeping with C5, the typical dysfunction will be either FRSL or FRSR, meaning that C5 is flexed, rotated and sidebent to the right or left. This dysfunction will bias the C5 disc posterior and to either the right or left side depending on the side of rotation and side bending.
Begining to adjust these mechanics will make a world of difference to the patient, as it will decrease the protective neural responce, decrease sympathetic tone throughout the cervical spine, decrease protective muscle spasm, improve cervical mobility, decrease paresthesias, decreaseradiculopathy, improve blood flow, improve strength, etc.
Correcting these mechanics even has the potential for eliminating the disc herniation all together. It has been confirmed for me viaMRI imaging.
Of courese I would integrate this work with an appropriate stretching regieme, modalities as necessary and neuromuscular re-education.
