A Retrospective Study on Traumatic Elbow Dislocation in Adults in a Tertiary Hospital in Riyadh, Saudi Arabia

Background This retrospective chart review aimed to ascertain the frequency and characteristics of radial head fractures in adults who presented to our emergency department with elbow dislocation. Methodology This study was conducted in a single tertiary trauma center in Riyadh, Saudi Arabia, between July 2015 and July 2020 to identify traumatic elbow dislocation in adults. Patients were identified after thoroughly examining the hospital's electronic X-ray database. In addition, computed tomography (CT) was used to assess complete ulnohumeral joint dislocation. In total, 80 patients between the ages of 18 and 65 were evaluated for a radial head fracture. Various variables were examined. Results Of the 80 patients included, the mean age with standard deviation was 36.9 +/- 8.8 years, and all patients were males. Nearly all patients with elbow dislocation had some form of posterior dislocation, including posterolateral (81.3%), posterior (10%), and posteromedial (7.5%) dislocation. The radial head fracture was identified in 48 (60%) cases. Radiographs were sufficient to diagnose 91.3% of radial head fractures, while the remaining 8.8% required additional CT. Conclusions Based on X-ray or CT findings, radial head fractures were found in more than half of traumatic elbow dislocations. In addition, most cases were diagnosed as an elbow dislocation and radial head fracture using only plain radiography, while some required additional CT. Based on these findings, we recommend routine CT to detect suspected elbow dislocation and avoid missing subtle injuries.
