title: Importance of Pelvic Radiography for Initial Trauma Assessment: An Orthopedic Perspective.
abstract: BACKGROUND
  Many institutions have abandoned the routine for selective pelvic x-ray (PXR) for initial imaging in blunt trauma patients undergoing computed tomography (CT) scanning.
  
  
  OBJECTIVE
  Our aim was to examine the association between selective use of PXR and time to diagnosis of (major) pelvic fractures, as well as prioritization of key immediate interventions (including hip reduction and pelvic arterial embolization).
  
  
  METHODS
  We conducted a 1-year review of early management of pelvic fracture patients undergoing pelvic CT scanning. Time interval and sequence of initial imaging and key immediate interventions were recorded.
  
  
  RESULTS
  Of 218 pelvic fracture patients, 79 (36%) had no initial PXR, and instead had an initial CT scan. Time to first pelvic imaging in those patients was 48 min (standard deviation [SD] = 47 min vs. 2 min [SD = 6 min] with PXR; p < 0.001). Of 40 hip dislocations, 15 (38%) were detected first on CT scan. Overall, 22 (55%) required a second CT scan after reduction in the emergency department. No initial PXR was performed in 42 of 120 (35%) pelvic ring fracture patients and in 16 of 61 (26%) unstable pelvic ring fractures. Time to pelvic arterial embolization was longer in 4 patients without initial PXR than in 14 patients with PXR (296 min [SD = 206 min] vs. 170 min [SD = 76 min], respectively, p = 0.038).
  
  
  CONCLUSIONS
  Selective PXR was associated with a significant delay in recognition of (major) pelvic fractures, including those with associated hip dislocations and (potential) pelvic bleeding. PXR remains a useful screening tool to rapidly determine the need for immediate interventions and to allow early planning before CT scanning.
