Dirsek Travmasında Fizik Muayene Bulguları ile Radyografi Gerekliliğinin Belirlenmesi

Abstract

The purpose of this study was to estimate the presence of fracture and to determine radiography requirements through results obtained by evaluating the physical examination findings in elbow injury. Material and Method:This was a single center prospective study. All patients were evaluated in terms of trauma mechanism, inspection findings, presence of pain at palpation, pain with active movement, circulatory examination and loss of sensation. Sensitivity, specificity, positive and negative predictive value (NPV) were determined for each sign and each examination finding. Results:The study was performed with 47 patients. Fracture was determined in 10 patients (21.2%). Presence of pain at the elbow extansion, forearm supination (FS), medial epicondyle (ME) palpation and forearm pronation tests exhibited high sensitivity (100%, 100%, 90%, and 80%, respectively) and high NPV (100%, 95%, 96.4%, and 91%, respectively) for elbow fracture. These four tests produced significant p values (0.088, 0.012, 0.001, and 0.079, respectively) in elbow fractures. Combining the pain at FS and ME palpation tests exhibited 90% sensitivity, and 96.7% NPV. Conclusions:Positivity on any one of the four tests employed increases the probability of fracture and is sufficient for elbow radiography to be recommended in patients presenting due to elbow injury. However, radiography may not be required if combined FS and ME palpation test findings are negative in this patients.
