these kinds of findings , along with minor disc wedging , bulges, lipping, calcification and other attention grabbing artifacts are for the most part entirely irrelevant. To be lead toward the largely medical diagnostic POV that these marginal physical defects are responsible for pain , would be to entirely miss the physiological/aetiological point. That being , it is protective behaviour leading to loss of normal movement dynamics that is the ubiquitous and more important issue to note. The movement capabilities of joints do not appear on x-rays or other computer aided scans. This can only be discovered by observation and handling. By becoming absorbed in a fruitless exercise in name the anomoly, the neophyte may fail to spot the obvious.
