J Shoulder Elbow Surg. A recent case study suggested a rapid change in the humeral retrotorsion angle … Relationship between humeral torsion and injury in professional baseball pitchers. Results: Measurements The humeral torsion angle is the obtuse angle formed between the orientation of the hu- meral head and the orientation of the distal condyles of the humerus (fig.1a–d). The identified associations include altered glenoid version [1], decreased humeral torsion [2], and variations in proximal humeral and acromial morphologies [3]. Humeral torsion describes the angular difference between the orientation of the proximal humeral head and the axis of the elbow at the distal humerus. Differences between results in terms of sex and age groups were evaluated with the Mann-Whitney U test. NLM doi: 10.7860/JCDR/2016/22121.8672. 3 ).
