60 patients, over 18 years of age, who were diagnosed with anterior or posterior glenohumeral shoulder dislocation were randomly assigned into one of two groups to compare the efficacy of shoulder reduction treatment with the Oxford chair (group 1) to a traditional shoulder reduction treatment (group 2). Results of the study indicated that there were no differences between the groups with regards to length of stay in the emergency department, procedure time, or pain experienced before or after treatments were completed. However, a significant difference in success rate was found, favouring the traditional treatment group over the Oxford chair method.
