Value of the 45-degree reverse oblique view of the carpal palm in diagnosing scaphoid waist fractures

•The 45° reverse oblique view clearly shows the scaphoid oblique view in the long axis for better observation of the scaphoid waist fracture and displacement.•The 45° reverse oblique view can be used as a routine X-ray examination view.•The 45° reverse oblique view can better demonstrate the amount of displacement present in a scaphoid waist fracture compared with PA, lateral, and Stecher views. To investigate the value of 45° reverse oblique view of the carpal palm in diagnosing scaphoid waist fracture and displacement. Eighty-four patients with wrist injury and plain radiography including posteroanterior, lateral, Stecher, and 45° reverse oblique view of the wrist were analyzed for the detection rate in diagnosing scaphoid fractures and displacement. The degree of difficulty in the four views for detecting the scaphoid waist fracture and displacement was rated on a five-grade Likert scale. Among 84 patients, scaphoid waist fractures occurred in 43, and fracture displacement in 32. A significantly (P
