Scans for open book pelvic fracture are usually performed on a common CT table and the patient lies on a soft 5-cm buttress. This soft mattress has been designed to give a minimal discomfort for the patients during the exam but it does, even with minimal forces, carry the risk of closing the pelvis. The study reports two cases of under-evaluation of open book lesion in CT scan performed in a common soft bed. According to our results, although they are limited, the mattress of the standard CT scan bed exerts a closing force to the affected side of a B1 type lesion. This effect is more evident in patients with higher weight. The closing force could be a problem when patients present equivocal findings at physical examination. According to our opinion, CT scans for pelvic trauma should be done on the table without the mattress.
