عنوان انگلیسی Bedside Ultrasonography for Early Diagnosis of Occult Radial Head Fractures in Emergency Room: A CTComparative Diagnostic Study
چکیده انگلیسی مقاله Purpose: To determine the value of bedside ultrasonography for the detection of Mason I radial head fractures that are non-visible in early X-ray's. Methods: A prospective, blind, single-center, diagnostic study was conducted (from June 2012 till May 2013) concerning 23 patients who were clinically suspicious of having a radial head fracture. These patients were evaluated with a bedside high frequency ultrasound in the Emergency Room. The two sonographic criteria that were considered to be diagnostic for fracture were: a. effusion besides the radial head-neck and b. cortical discontinuity of the radial head or neck. All patients also underwent a Computed Tomography (CT) as the gold standard imaging modality for the diagnosis of occult radial head fractures in order to compare these results with the ultrasound findings. Results: Fifteen out of 23 patients were diagnosed suffering from radial head fracture, with the use of both the ultrasound and the CT. On the other hand, there were three patients with negative ultrasound and positive CT, while two patients were found positive in the ultrasonographic exam, while this result was not confirmed by the CT scan. In comparison with the CT, ultrasound exam appeared to have 83.3% sensitivity, 60% specificity88.2% positive prognostic value and 50% negative prognostic value (when at least one diagnostic sonographic criterion was positive). The accuracy of the sonographic study for the diagnosis of the above-mentioned fractures was found 78.2%. The most sensitive sonographic sign was the detection of effusion in contact with the radial neck (14/15 of the true positive radial head ultrasounds). Conclusions: Bedside ultrasound in the E.R. was proven to be a sensitive tool for the early (day-1) diagnosis of the occult radial head fractures. It could be used as an adjacent imaging modality in patients suspicious for radial head fracture, when the initial X-rays are negative.
