    Implementation of Quebec Shoulder Dislocation Rule in Turkish Patient Population
    (Aves, 2018) Temiz, Aytun; Das, Murat
    Aim: The aim of this study was to investigate whether the Quebec Shoulder Dislocation Rule (QSDR) is valid in Turkish patient population. Materials and Methods: Adult patients with an anterior shoulder dislocation were enrolled in this study. Patients with a severe head injury, multiple trauma, and drug or alcohol intoxication were excluded. All patients were classified according to the associated fracture status. Patients with fracture dislocation were classified as case group (group 1) and patients with isolated dislocation were included to the control group (group 2). Group 1 and 2 patients were statistically compared in terms of risk factors defined by QSDR. Diagnostic performance of this decision tool in predicting a clinically significant fracture was studied. Sensitivity, specificity, positive predictive value, and negative predictive value were calculated. Results: A total of 248 patients were included in the study. Fracture dislocation was detected in 63 (25.40%) patients (group 1), and no complicated dislocation was detected in 185 (74.59%) patients (group 2). Statistically significant difference was found between groups 1 and 2 in terms of risk factors defined by the QSDR. Sensitivity, specificity, and positive and negative predictive values of the Quebec rule were detected as 100%, 33.51%, 33.87%, and 98.41%, respectively. Conclusion: Our study suggests that QSDR is a useful decision tool to estimate which patient has fracture dislocation of the shoulder in Turkish population. We think that if a shoulder dislocation patient is Quebec-, pre-reduction X-ray could be safely omitted.
