**3.1 Pain relief**

Pain relief is the most predictable outcome following hemiarthroplasty for four-part proximal humerus fractures. Many authors have supported this finding, with 61% to 97% of patients reporting complete patiens reporting pain relief. Significant resifual pain generally tends to be associated with moderate activity; minimal pain occurs at rest. Even when motion and functional results are limited, pain relief is reported to be consistent (Young et al 2010).
