Abduction is the most frequent performed action to which are connected the most frequent shoulder pathologies, but there is not agreement how to describe it. One of the most qualified description divides the abduction in four parts. The revision of the papers that analyzed the movement from quantitative view-point suggests it can be divided in two phases. The first until 30°of rotation during which there is a prevalent rotation of the humerus respect to others. Further 30°the shoulder components show a linear behaviour which definitive quantification has not jet been obtained. After all the clavicula has stabilizing function that does not affect shoulder range of motion. The other two elements can mainly condition their mobility each other. So it is questionable the subdivision of the abduction in four phases.
