<span style="font-family: arial, sans-serif; font-size: 13px;">Of pediatric patients who have anteroposterior (AP) pelvic xrays (XR), there is </span><span style="font-family: arial, sans-serif; font-size: 13px;">a 4.6% rate of pelvic fracture or dislocation, compared to 10% in </span><span style="font-family: arial, sans-serif; font-size: 13px;">adults.</span><br style="font-family: arial, sans-serif; font-size: 13px;" />
<br style="font-family: arial, sans-serif; font-size: 13px;" />
<span style="font-family: arial, sans-serif; font-size: 13px;">This study is a sub analysis of a prospective observational cohort of </span><span style="font-family: arial, sans-serif; font-size: 13px;">children with blunt torso trauma conducted by PECARN. 7808 patients </span><span style="font-family: arial, sans-serif; font-size: 13px;">had pelvic imaging, with 65% of them having an AP XR. The XR </span><span style="font-family: arial, sans-serif; font-size: 13px;">sensitivity ranged from 64-82% (based on age groups) for detecting </span><span style="font-family: arial, sans-serif; font-size: 13px;">fractures. All but one patient with a pelvic fracture not detected on </span><span style="font-family: arial, sans-serif; font-size: 13px;">XR had a CT scan. The CT scan detected all but 2 fractures both of </span><span style="font-family: arial, sans-serif; font-size: 13px;">which were picked up later as healing fractures on repeat pelvic XR. </span><span style="font-family: arial, sans-serif; font-size: 13px;">Some of the patients who had a missed fracture on XR were </span><span style="font-family: arial, sans-serif; font-size: 13px;">hemodynamically unstable or wound up requiring operative intervention.</span><br style="font-family: arial, sans-serif; font-size: 13px;" />
<br style="font-family: arial, sans-serif; font-size: 13px;" />
<span style="font-family: arial, sans-serif; font-size: 13px;">The authors support the following algorithm:</span><br style="font-family: arial, sans-serif; font-size: 13px;" />
<br style="font-family: arial, sans-serif; font-size: 13px;" />
<span style="font-family: arial, sans-serif; font-size: 13px;">-With hemodynamically unstability children, obtain a pelvic XR</span><br style="font-family: arial, sans-serif; font-size: 13px;" />
<br style="font-family: arial, sans-serif; font-size: 13px;" />
<span style="font-family: arial, sans-serif; font-size: 13px;">-For hemodynamically stable children when the physician is planning to </span><span style="font-family: arial, sans-serif; font-size: 13px;">get a CT, there is no indication for XR</span><br style="font-family: arial, sans-serif; font-size: 13px;" />
<br style="font-family: arial, sans-serif; font-size: 13px;" />
<span style="font-family: arial, sans-serif; font-size: 13px;">Bottom line: Consider using AP pelvic radiographs in the </span><span style="font-family: arial, sans-serif; font-size: 13px;">hemodynamically stable patient with a high suspicion for fracture or </span><span style="font-family: arial, sans-serif; font-size: 13px;">dislocation who are not undergoing CT.</span></p>
