I find it interesting how the way medicine is sometimes practiced in this part of the world. As a broad generalization it still often focus on treating the symptoms of a problem without even considering the cause or trying to prevent further recurrences in the future.
As a typical example a patient who has unilateral nerve root impingement at C5/6 due to non traumatic aetiology will possibly opt to have an anterior stabilization/fusion procedure. The symptoms are resolved after and the surgery is declared a success. The underlying cause which is often poor posture, ergonomics and body awareness is never addressed so the problem then repeats itself at the level above. Now this may or may not be a slightly more challenging prospect to have to deal with. My experience has been that the “trauma” of the surgery often leaves the tissues in a slightly hypersensitive state so when the level above start playing up the resulting pain and inflammation is more difficult to reduce.
