25 patients with an anterior glenohumeral dislocation were randomly assigned to have their shoulder immobilized in either external or internal rotation. The study was conducted in order to determine whether immobilizing in external rotation was superior to internal rotation in terms of reducing the separation, displacement, and opening angle of the shoulder. The results of this study displayed that although the external rotation group reported lower values for all three outcomes, results were only significant in terms of shoulder separation. The small sample size of this trial and potential additional expenses associated with immobilisation in external rotation highlight the need for further clinical trials..
