Radiography of the carpal scaphoid. An experimental investigation evaluating the use of oblique projections.

An experimental investigation demonstrating the value of oblique projections in radiographic examination of possible scaphoid fractures is described. Three cadaver specimens were used, fractured in different places, and radiographs were obtained at different angulations with respect to the vertical plane. Even nondislocated fractures were well demonstrated and it was concluded that a p.a. projection with the tube tilted about 40 degrees distally should always be included in radiographic examination of the carpal scaphoid.
