![]() Much of the debate centers around what is the minimum radiographic workup necessary prior to removing cervical immobilization devices. There is considerable debate regarding "clearance of the cervical spine" in trauma patients who are uncooperative or unable to give a reliable history. We therefore cannot recommend the use of ULCR in the obtunded trauma patient. ULCR are inferior to both CT and MRI in the detection of cervical injury in patients with normal plain radiographs. ULCR had an apparent sensitivity of 45.5% and specificity of 71.4%. None of the missed injuries required surgical stabilization, although one had a vertebral artery injury demonstrated on subsequent angiography. Six patients had ULCR interpreted as normal, but had abnormalities on either CT or MRI. The seventh patient's only abnormality was soft tissue swelling MRI was otherwise normal. Seven patients had studies interpreted to be abnormal, of which six were also abnormal, by either CT or MRI. We retrospectively reviewed our experience with ULCR in 683 blunt trauma victims who presented over a 3-year period, with either a Glasgow Coma Score <13 or who were intubated at the time of presentation. An upright lateral cervical radiograph (ULCR) was performed in selected patients to investigate whether this study could provide this same information, to enable removal of cervical immobilization devices in the multiple trauma patient. Dynamic radiographs or MRI are thought to demonstrate unstable injuries, but can be expensive and cumbersome to obtain. The best method for radiographic "clearance" of the cervical spine in obtunded patients prior to removal of cervical immobilization devices remains debated. ![]()
