Many patients with shoulder injuries undergo X-rays even when fractures are unlikely, leading to unnecessary costs and delays in care. This study aims to develop a simple and reliable clinical tool to help healthcare providers determine when imaging is not required. By evaluating this tool in a large number of patients, we aim to improve patient care, reduce waiting times, and optimize the use of healthcare resources.
Abstract Shoulder trauma is a common presentation in orthopedic and emergency settings and frequently leads to routine radiographic imaging despite a relatively low prevalence of fractures. This practice contributes to increased healthcare costs, unnecessary radiation exposure, and inefficiencies in patient flow. Currently, no validated clinical decision rule exists to safely exclude shoulder fractures. We will conduct a prospective, multicentre diagnostic accuracy study in a high-volume orthopedic setting, enrolling approximately 1200 adult patients presenting with acute shoulder trauma. The study will include derivation and external validation cohorts. All participants will undergo standardized clinical assessment using the SFER clinical decision rule, followed by radiographic imaging as the reference standard. The primary outcome is sensitivity for fracture detection, with secondary outcomes including specificity, negative predictive value, reduction in imaging rates, missed fracture rate, inter-rater reliability, and cost-effectiveness. We hypothesize that the SFER rule will achieve sensitivity ≥95% with a missed fracture rate \<1%, enabling safe reduction of unnecessary imaging and improving clinical efficiency.

All participants will undergo assessment using a structured clinical decision framework designed to stratify patients with acute shoulder trauma into high- and low-risk categories for fracture. In the initial stage, patients will be screened for high-risk features based on demographic factors, symptom severity, and mechanism of injury. Individuals meeting any high-risk criteria will be referred for immediate radiographic evaluation. Patients not classified as high-risk will proceed to a secondary functional assessment stage. This stage incorporates a series of standardized clinical tests evaluating range of motion, localized tenderness, functional loading capacity, and soft tissue signs. Fracture will be considered unlikely only when all functional criteria are within normal limits. Radiographic imaging will be indicated if any abnormal finding is identified during assessment. All variables will be predefined and recorded using standardized criteria to ensure reproducibility and minim
Radiographic imaging (X-ray) will be performed for all participants and will serve as the reference standard for fracture diagnosis. Radiographs will be interpreted by qualified radiologists who will be blinded to the results of the clinical assessment to reduce diagnostic bias.
