The Study: Impact of Cervical Sagittal Alignment Parameters on Neck Disability
- The authors wished to find out in a group of patients who were indicated for surgery if cervical alignment was a predictor of disability in that group prior to their surgery.
- They looked at 90 patients.
- They found that increasing CL (C2-C7 angle ie. cervical lordosis) and increasing TS (T1 slope) were correlated with decreasing neck disability index.
- They also found that increasing TS-CL (TS minus CL) was correlated with decreasing neck disability index.
- In the Key Points they said, "This is the first study to show a preopertiave relationship between cervical sagittal alignment and NDI.
They found that increasing Cervical Lordosis and T1 slope, along with increasing TS-CL were correlated with decreasing NDI. Again and again we see that spinal alignment matters.

Editors Comments: We review articles like this nearly every week now and I would ask this simple question of those in our academic community, as well as doctors in the field who may feel that our only job is to restore joint motion/mobility. As the literature supporting the importance of structural balance to improved patient outcomes continues to be written by our competition, how long before chiropractic becomes irrelevant in terms of providing structural corrective care and we are permanently identified as nothing more than spinal manipulators providing an overpriced form of short term pain relief?
