The author asserts that if an instability is of any consequence, then it can be detected during the physical examination by a trained observer. Radiographs, which display full-range or even paradoxical movements, do not represent true functional movements. If the instability cannot be seen or palpated there is a serious question as to whether it exists. Hypermobility can also be detected and differentiated from instability.
