Examination of scaphoid fracture

The diagnosis of scaphoid fracture depends on reliable imaging examination. X-ray plain film is a preliminary screening method. When scaphoid fracture is suspected, multi-position X-ray plain film (positive position, lateral position, oblique position, scaphoid position, etc. ) it should be taken. As long as the cortical bone or trabecular shadow is clearly seen on the X-ray film at any position, the diagnosis can be established. If there is no fracture shadow on the acute X-ray plain film, further CT examination can confirm the diagnosis. Where the conditions are limited, the wrist joint can be fixed with plaster for about 2 weeks, and then the X-ray plain films in multiple positions can be reviewed. At this time, the fracture line will be more obvious because of bone absorption. Magnetic resonance imaging (MRI) is not more sensitive than CT in the diagnosis of scaphoid fracture, so it is generally not the first choice for examination, and it is only meaningful when it may be complicated with other ligament injuries.
