Presentation
This patient presented with a history of slip and fall, followed by severe elbow pain on supination-pronation movements.
Patient Data
The lateral radiograph of the involved elbow shows a positive sail sign:
the elevation of the anterior fat pad of the elbow
visible and elevated (normally non-visualised) posterior fat pad of the elbow
CT sagittal images show a non-displaced extra-articular hairline fracture along the anterior aspect of the head of radius, seen as subtle cortical stepping and focal loss of trabecular continuity.
