Displacement of More than Three Millimeters Might Influence Shoulder Function: A Retrospective Analysis of Minimally Displaced Fractures of the Greater Tuberosity

Abstract

There is no clear evidence in the literature as to whether minimally displaced fractures of the greater tuberosity should be reduced and stabilised by operative means or if the results of conservative treatment are good. The aim of this study was to find out if the amount of displacement in conservatively treated patients had an effect on shoulder function. We were able to examine 135 patients with fractures of the greater tuberosity treated between 1992 and 2000 at an average time of 3.7 (2±10) years after trauma. The results showed that patients with less than 4 millimeters of displacement had the same outcome with either simple shoulder slings or with Gilchrist bandages. Displacement of less than 4 millimeters appeared to have no effect on shoulder function. However, patients with a displacement of more than three millimeters obviously had a worse result compared to the patients with less displacement. We suggest cheaper shoulder slings for conservative treatment and operative treatment in patients with a displacement of more than three millimeters.
