Abstract
The clinical value of the pronator quadratus radiological sign was investigated. Fresh undisplaced fractures of the distal radius and acute injuries of the distal radio-ulnar joint showed anterior displacement of the radiolucent shadow in 85% and 88% respectively, but normal subjects no displacement. In rheumatoid arthritis, the presence of synovitis of the wrist joint appeared to be correlated with a blurred shadow at the distal end.Keywords
