The LS uses a linear scanning technique with a highly collimated (laser-like) X-ray fan beam, which spreads out in only one direction. In the quest for improved imaging techniques in the emergency room, the Lodox-Statscan (LS), initially used in the South African mining industry to reduce diamond theft, has evolved into a promising time-saving diagnostic tool. If any of these criteria are met, the next step is radiological imaging, which is pivotal for the correct diagnosis and treatment of spinal injuries. Moreover, in the clinical examination, a spinal injury is assumed when a patient suffers from any spinal pain, hand or foot weakness or altered sensation, priapism (unconscious or exposed male) or a history of past spinal problems, including previous spinal surgery or conditions that predispose to the instability of the spine. According to the guidelines of the National Institute for Clinical Excellence (NICE), spinal injuries are suspected if a patient has any significant distracting injuries, a reduced level of consciousness or is under the influence of drugs or alcohol, which might be associated with confusion or uncooperativeness. The early identification of spinal injuries is critical in the initial management of the trauma patient to avoid adverse events due to incorrect immobilization and mismanagement. Spinal injuries are a common finding in polytraumatized patients with an incidence of 18–40%. However, if spinal injuries are suspected, performing a full-body CT scan is necessary for correct diagnosis. In polytraumatized patients, AP-LS, implemented in the Advanced Trauma Life Support-algorithm, is a helpful tool to diagnose life-threatening injuries. This study demonstrated high specificity with low sensitivity of AP-LS in detecting spinal injuries compared to CT scan. Potentially unstable spinal injuries were more likely to be detected than stable injuries (sensitivity 18 and 6%, respectively). The sensitivity was highest for thoracic spinal injuries (14%). AP-LS had a low sensitivity of 9% (31 of 332, range 0–24%) and high specificity of 99% (range 98–100%). On CT scan, 207 patients presented with a spinal injury (65%, total of 332 injuries). The study group included 320 patients (48.5 years ☑9.5, 89 women). The sensitivity of AP-LS was further analyzed by the severity of spinal injuries. Interrater reliability between the three observers was calculated using Fleiss’ Kappa. The diagnostic accuracy was evaluated by using the area under the ROC (receiver operating characteristic curve) for sensitivity and specificity. The sensitivity and specificity of correct diagnosis with AP-LS compared to CT scan were calculated. Therefore, within 3 years, AP-LS of polytraumatized patients (ISS ≥ 16) were retrospectively analyzed by three independent observers. We aimed to analyze the diagnostic accuracy and the interrater reliability of AP-LS to detect spinal injuries in polytraumatized patients. The Lodox-Statscan (LS) has evolved into a promising time-saving diagnostic tool to diagnose life-threatening injuries with an anterior-posterior (AP)-full-body digital X-ray. Rapid identification of spinal injuries requiring immobilization or operative treatment is essential. Associated cervical spine fractures are common.Spinal injuries are present in 16–31% of polytraumatized patients. ![]() In older patients, the C2 vertebral body is commonly affected due to degenerative ankylosis of lower levels. is a hyperextension injury) with resulting avulsion of the anteroinferior corner of the vertebral body.
