Abstract
BACKGROUND:: Pulled elbow is a disorder commonly observed in children in routine medical practice; however, when the circumstances involved in the injury are unknown, difficulty has been encountered in differential diagnosis whether it is a bone fracture or pulled elbow. One of the reasons involved has been the unavailability of diagnostic imaging in confirming the diagnosis of the pulled elbow. Therefore, the author had performed ultrasonography for the pulled elbow and studied the specific ultrasonographic findings of the same.
METHODS:: Using as subjects a total of 70 cases of pulled elbow, with their age ranging from 4 months to 6 years, ultrasonography was performed from September 2010 to February 2013 with the use of Hitachi EUB 7500 ultrasonographic apparatus with a 12 MHz transducer. Careful observation was made of the specific ultrasonographic images of anterior long-axis view of the radiohumeral joint before and after the manipulation.
