History : 28 yr old man with wrist pain following a fall
on outstretched hand
Answers
What does the radiograph show ?
Lunate dislocation – the lunate is displaced anteriorly and appears ‘empty’
Why is this injury not a perilunate dislocation ?
The capitate and radius remain in a straight line. In perilunate dislocation, the capitate is displaced posteriorly and is no longer in a straight line with the radius.
