Interobserver variability among radiologists for diagnosis of scaphoid fractures by computed tomography.

Purpose: To determine the interobserver variability among radiologists for computed tomography (CT) diagnosis of scaphoid fractures.

Methods: Four specialized musculoskeletal radiologists evaluated the CT scans of 150 consecutive patients who were clinically suspected of having sustained a scaphoid fracture but whose scaphoid-specific radiographs were normal. The radiologists were asked to determine the presence or absence of a scaphoid fracture and to localize the fracture.
