Exploración y evaluación radiológica de la articulación acromioclavicular

The subcutaneous location of the acromioclavicular joint allows the clinician to evaluate deformities directly and palpate the joint. This is more complicated in the glenohumeral joint. However, pain arising from the joint can irradiate to different areas of the shoulder, arm and neck, and can be misleading. Thus, it is important to be familiar with the spectrum of physical examination tests, specific radiological projections and MRI findings in order to reach an accurate diagnosis.

The aim of this article is to systematically describe the most commonly used physical examination tests for acromioclavicular pathology, including sensitivity, specificity, and predictive values for all of them. Secondly, to analyse the radiological particularities of this joint and to establish the usefulness of the specific projections and imaging techniques.
