Answer for CoW 09 April 2017
Findings
Lunate dislocates anteriorly Radius and capitate remain in a straight line Concavity of lunate is empty ‘piece of pie’ sign of lunate on AP
Discussion
Key radiological findings include: Dislocation of the lunate from the lunate fossa (usually volar) into the space of poirier, also known as the ‘spilled tea cup’ sign, with loss of colinearity of the radius, lunate and capitate Interruption of Gilula's lines The ‘piece of pie’ sign representing the lunate on true Anteroposterior (AP) x-ray views Lunate and capitate overlap An abnormal scapho-lunate angle of >70 or <30°.
