Papel de la disfunción escapulotorácica en la afección de la articulación acromioclavicular

The scapulothoracic and acromioclavicular (AC) joints are inter-related to form the shoulder suspensory complex. Therefore, patients with any kind of AC dislocation may present with biomechanical scapular alterations and suffer scapular dyskinesis.

In the present article, the concept of dyskinesis is reviewed, as well as the evaluation criteria and the different types of classifications.

The relationship between acromioclavicular joint dislocation and dyskinesis is also assessed. The anatomic aspects, the increased presence of dyskinesis within the different kind of AC injuries and their causative hypothesis are also reviewed. Finally, the results of the rehabilitation program and the surgical treatment for type III AC dislocations are reviewed in relation to dyskinesis.
