Earthquake trauma is diverse, but many victims suffer from crush injuries from building collapses.<a class="elsevierStyleCrossRefs" href="#bib2">2,3</a> Non-earthquake traumas, by contrast, usually do not include crush injuries. In light of the unique presentations of earthquake-related trauma, it is necessary to study this type of injury. The features of earthquake-related injuries in abdominal, spinal, and pelvic trauma patients have been thoroughly described in previous studies.<a class="elsevierStyleCrossRefs" href="#bib4">4–6</a>Non-earthquake-related head injuries have contributed significantly to trauma-related deaths, accounting for up to one half of all deaths.<a class="elsevierStyleCrossRef" href="#bib7">7</a> Similarly, in earthquake-related traumas, head injuries account for 30% of fatalities.<a class="elsevierStyleCrossRefs" href="#bib1">1,8</a> Although head trauma is common and deadly in both earthquake- and non-earthquake-related traumas, the features of the injuries may be different because of different injury circumstances. Accordingly, we retrospectively reviewed computed tomography (CT) data and compared the findings of head traumas caused by the Sichuan earthquake with traumas caused by other common factors in daily life with the aim of determining the distinctive features of earthquake-related head traumas.MATERIALS AND METHODSParticipantsThe local institutional ethical review board approved the present study, and informed consent was waived because of the retrospective nature of this study. The study subjects were patients with head traumas caused by the Sichuan earthquake from the 12th to the 25th of May 2008 as well as head traumas caused by typical, non-earthquake-related traumas over a similar time frame from the 1st to the 30th of May 2009. To illustrate the features more clearly, we chose as a control group consecutive patients with non–earthquake-related head traumas at the same university hospital during a similar period one year after the major earthquake to avoid bias arising from the different seasons and the confounding influence of the earthquake–related situations. We applied the following inclusion criteria: 1) the patients should have had a definite history of head trauma, 2) the patients should have had no surgical treatment before undergoing a CT examination, 3) the CT scan should have covered all injured parts of the head, and 4) the CT image should have been of adequate quality for the diagnosis. Among the patients with earthquake-related head traumas, any patient whose trauma resulted from falling or from a traffic accident during the earthquake was excluded. Finally, 221 cases with earthquake-related head traumas and 221 cases with non-earthquake-related traumas were enrolled into this study.CT ProtocolsThe head CT scans of 39, 308, and 95 patients were obtained using a Philips Brilliance 16 slice multiple detector row CT scanner (Philips Medical Systems, Eindhoven, the Netherlands), a Siemens Somatom Sensation 16 and a Siemens Somatom Plus 4, and a multiple detector CT scan (Siemens Medical Systems, Forchheim, Germany), respectively. According to the injury site and physical examination, cranial, maxillofacial, and cranio-maxillofacial CT scans were performed in 248, 102, and 91 patients, respectively. The cranial and maxillofacial CT scans were performed from the base to the roof of the skull and from the supraorbital margin to the inferior margin of the chin, respectively. The scanning parameters were 120 kV, 200-440 mAs, 0.5-s rotation time, pitch of 0.891, and collimation of 16×0.75 mm for the Philips Brilliance 16–MDCT scanner; 120 kV, 200-250 mAs, 0.5-s rotation time, pitch of 0.85, and collimation of 16×0.75 mm for the Siemens Somatom Sensation 16-MDCT scan; and 120 KV, 180-260 mAs, 0.5-s rotation time, pitch of 1.5, and collimation of 4×0.75 mm for the Siemens Somatom Plus 4-MDCT scan. The lower current (200 or 180 mAs) was used for the maxillofacial CT scan. The reconstructed section thickness was 8 mm for the cranial CT and 1 mm for the maxillofacial CT. The sagittal and coronary images used to observe maxillofacial and basal fractures were reconstructed with a thickness of 1-3 mm.Image reviewAll of the MDCT scans were reviewed by the authors on the Syngo workflow picture archiving and communicating system workstation (Siemens Medical Systems, Forchheim, Germany). The cranio-maxillofacial soft tissue, bones, and brain were reviewed, and the anatomic distributions or types of injuries were recorded. Discrepancies with regard to the interpretations were resolved by consensus. The window width and window level used in reviewing the images were as follows: soft tissue (W: 350 HU, L: 50 HU), bone (W: 3200 HU, L: 700 HU), and brain (W: 80 HU, L: 35 HU).Injuries only involving the scalp and/or maxillofacial soft tissue were classified as extracranial soft tissue injuries. When the fractures were evaluated, the whole head was divided into cranial and maxillofacial regions. The anatomical sites of the cranial region included the frontal, parietal, temporal, sphenoid, and occipital bones, and those of the maxillofacial region included the nasal and ethmoid bones, zygoma, orbit, maxilla, and mandible. The diagnosis of the fractures was achieved with transverse plane and multi-planar reformation (MPR) as well as with three-dimensional (3D) reconstructions (volume rendering, VR; surface shade display, SSD). Craniocerebral injury was traumatic injury involving the scalp, cranium, or intracranial structures (i.e., brain, meninges, and other structures), whereas intracranial injury was injury that only involved the intracranial structures. Intracranial injuries included extradural hematoma, subdural hematoma, subarachnoid hemorrhage, cephalophyma, pneumocephalus, cerebral edema and cerebral contusions, and lacerations.Statistical analysisThe patients' ages and sexes and the cause of injury for the patients with non-earthquake traumas were recorded. The numbers of patients with simple head soft tissue injuries, fractures, and intracranial injuries as well as the numbers of fractures and intracranial injuries in the patients were counted. Moreover, the proportions of soft tissue injuries, skull fractures, maxillofacial fractures, and cranio-maxillofacial fractures combined with intracranial injuries in both groups were calculated. The continuous variables were expressed as means±standard deviation, and the categorical variables were expressed as numbers and percentages. An independent-sample t-test and chi-square test were used to compare the continuous variables and the categorical variables in both groups, respectively. Statistical analysis was performed with the SPSS statistical package (version 13.0 for Windows, SPSS Inc., Chicago, IL, USA). A two-tailed p-value of less than 0.05 was accepted as indicating a statistically significant difference.RESULTSThe baseline characteristics of the patients in the earthquake and non-earthquake groups are shown in <a class="elsevierStyleCrossRef" href="#tbl1">Table 1</a>. There were fewer male patients in the earthquake group than in the non-earthquake group (p<0.01). The patients' age distributions in both groups are shown in <a class="elsevierStyleCrossRef" href="#fig1">Figure 1</a> with no significant differences (p>0.05), but there were more cases with ages ranging from 20 to 50 years in the non-earthquake group (p<0.01). The mean time from injury to CT scan among the earthquake patients was longer than that for the non-earthquake patients. The mortality was relatively high in the non-earthquake group. The non-earthquake trauma causalities are summarized in <a class="elsevierStyleCrossRef" href="#tbl2">Table 2</a>.<elsevierMultimedia ident="tbl1"></elsevierMultimedia><elsevierMultimedia ident="fig1"></elsevierMultimedia><elsevierMultimedia ident="tbl2"></elsevierMultimedia>Comparison of the types and the regions of head injuriesExtracranial soft tissue injuries, fractures, and intracranial injuries were detected in 112 (50.7%), 97 (43.9%), and 38 (17.2%) cases in the earthquake group, respectively, and we found 58 (26.2%), 117 (52.9%), and 112 (50.7%) cases in the non-earthquake group, respectively. The comparisons of different types of injuries between the two groups are shown in <a class="elsevierStyleCrossRef" href="#fig2">Figure 2</a>. Earthquake victims had more extracranial soft tissue injury cases (50.7% vs. 26.2%, RR = 1.9, p<0.001), but fewer patients had intracranial injuries (17.2% vs. 50.7%, RR = 0.3, p<0.001) than in the non-earthquake group. Among the earthquake victims with fractures and/or intracranial injuries, maxillofacial fractures and craniocerebral injuries were detected in 60 (55.0%) and 66 (60.6%) cases, respectively. These same maxillofacial fractures and craniocerebral injuries were detected in 73 (44.8%) and 127 (77.9%) patients, respectively, in the non-earthquake group. Craniocerebral injuries were significantly less frequent in the earthquake group than in the non-earthquake group (60.6% vs. 77.9%, RR = 0.8, p<0.01).<elsevierMultimedia ident="fig2"></elsevierMultimedia>Comparison of cranio-maxillofacial fracturesOne hundred forty-one (mean: 1.5±0.9 per patient, range: 1–8) fractures were found in 97 patients in the earthquake group, and 294 (mean: 2.5±1.8 per patient, range: 1–9) fractures were found in 127 patients in the non-earthquake group. Among these patients, the cases in the earthquake group had fewer fractures than those in the non-earthquake group (p<0.001) (<a class="elsevierStyleCrossRef" href="#fig3">Figure 3</a>). The fracture anatomic distributions in the cranial and maxillofacial regions for both groups are shown in <a class="elsevierStyleCrossRef" href="#tbl3">Table 3</a>. In the earthquake and non-earthquake groups, the temporal bone, orbit, and nasal and ethmoid bones were the most commonly involved sites in the cranial and maxillofacial regions. Compared with the patients with non-earthquake-related fractures, patients with earthquake-related fractures had more occipital bone and mandible fractures but fewer maxillary fractures (p<0.01).<elsevierMultimedia ident="fig3"></elsevierMultimedia><elsevierMultimedia ident="tbl3"></elsevierMultimedia>Comparison of the intracranial injuriesFifty (mean: 1.3±0.5 per patient, range: 1–3) intracranial injuries were found in 38 patients in the earthquake group, and 242 (mean: 2.1±1.1 per patient, range: 1–5) intracranial injuries were found in 112 patients in the non-earthquake group. Among these patients, the cases in the earthquake group had fewer intracranial injuries than did the patients in the non-earthquake group (p<0.001). The different intracranial injuries in both groups are shown in <a class="elsevierStyleCrossRef" href="#tbl4">Table 4</a>. The principal types of intracranial injuries in the earthquake and non-earthquake groups were subarachnoid hemorrhage versus cerebral contusions and lacerations, respectively. Cerebral contusions and lacerations were more common in the non-earthquake group than in the earthquake group (p<0.05). Moreover, contrecoup injuries (<a class="elsevierStyleCrossRef" href="#fig4">Figure 4</a>) were common in the non-earthquake group, and intracranial injuries were usually close to cranial fractures or scalp injuries (<a class="elsevierStyleCrossRef" href="#fig5">Figure 5</a>) in the earthquake group.<elsevierMultimedia ident="tbl4"></elsevierMultimedia><elsevierMultimedia ident="fig4"></elsevierMultimedia><elsevierMultimedia ident="fig5"></elsevierMultimedia>Comparison of the relationship between extracranial and intracranial injuriesIn the earthquake group, 12 (9.8%) of 123 patients with soft tissue injuries but no fractures, 6 (12.2%) of 49 patients with maxillofacial fractures, 13 (35.1%) of 37 with cranial fractures, and 7 (58.3%) of 12 with cranio-maxillofacial fractures had intracranial injuries, respectively. In the non-earthquake group, 45 (43.7%) of 103 patients with soft tissue injuries but no fractures, 8 (18.2%) of 44 with maxillofacial fractures, 37 (82.2%) of 45 with cranial fractures and 22 (75.9%) of 29 cases with cranio-maxillofacial fractures had intracranial injuries, respectively. A comparison of intracranial injuries among the different types of extracranial injuries is shown in <a class="elsevierStyleCrossRef" href="#fig6">Figure 6</a>. Compared with the non-earthquake group, the incidence of soft tissue injuries and cranial fractures combined with intracranial injuries was significantly lower in the earthquake group (9.8% vs. 43.7%, RR = 0.2; 35.1% vs. 82.2%, RR = 0.4, each p<0.001).<elsevierMultimedia ident="fig6"></elsevierMultimedia>Comparison of the combined injuries of head traumasIn the earthquake group, 35 (15.8%) patients had a total of 48 combined injuries (mean: 1.4±0.5 per patient, range: 1–3 injuries). In the non-earthquake group, 46 (20.8%) patients had a total of 91 combined injuries (mean: 2.0±0.8 per patient, range: 1–4 injuries). The combined injuries in both groups are shown in <a class="elsevierStyleCrossRef" href="#tbl5">Table 5</a>.<elsevierMultimedia ident="tbl5"></elsevierMultimedia>DISCUSSIONAccording to the clinical features of the patients in the earthquake and non-earthquake groups, we found that the age distributions in both groups were similar, but there were significantly more patients with ages ranging from 20–50 years old in the non-earthquake group. Additionally, male patients were also more common in the non-earthquake group than in the earthquake group. These differences were consistent with previous reports.<a class="elsevierStyleCrossRefs" href="#bib9">9,10</a> This difference possibly reflects the tendency of young and middle-aged male patients to engage in riskier social behaviors.We found that head traumas caused by the earthquake were possibly different from head traumas with other causes. Patients in the earthquake group had fewer overall fractures and intracranial injuries. Additionally, the earthquake group had more cases with extracranial soft tissue injuries, but fewer of these injuries coexisted with intracranial injuries. Finally, the extracranial injuries, especially the soft tissue injuries and cranial fractures, had a lower incidence of combined intracranial injuries in the earthquake group. Additionally, patients with head traumas in the earthquake group had fewer combined injuries. Generally, the earthquake-related head injuries as depicted on CT were less serious.Differences between the head traumas caused by the earthquake and other common traumas had a possibly direct relationship with the severity of the injuries. In an earthquake, head traumas commonly result from building collapses and falling objects,<a class="elsevierStyleCrossRefs" href="#bib2">2,11–14</a>, whereas non-earthquake-related traumas are frequently caused by traffic accidents and falls.<a class="elsevierStyleCrossRefs" href="#bib4">4,10,15,16</a> The energy of impact is significantly different between these two settings, and high-mass, low-velocity injuries may be more common among earthquake-related injuries than among non-earthquake injuries. In addition, patients in an earthquake have a little time to react to falling buildings. However, patients in traffic accidents or who have fallen are even more vulnerable, because the impact is so instantaneous that they have no time to protect themselves from the trauma, which perhaps makes these traumas more severe. In the present study, the head traumas in the earthquake group mainly resulted from building collapses, and the non-earthquake-related traumas from falls and traffic collisions were more serious than the traumas in the earthquake group.Similarly, injury mechanisms could also account for the different CT findings between earthquake-related and non-earthquake-related head traumas. The crush injuries caused by building collapses do not involve notable head motion after the initial collision. However, everyday traumas, such as those resulting from traffic collisions, cause deceleration injuries, which can also result in countercoup injuries from the relative motion of the brain.<a class="elsevierStyleCrossRefs" href="#bib10">10,17–19</a> Therefore, deceleration-related brain injuries are more common in non-earthquake-related head traumas and seem to cause more complicated brain injuries, such as the brain contusions and lacerations seen in this study.In addition, external conditions may also be responsible for the differences in head traumas. In the massive Sichuan earthquake, traffic accidents, complicated infrastructure, and aftershocks all delayed rescue to the outlying areas, and patients with severe injuries died before they could receive emergency services. By contrast, rescue in the downtown area of Chengdu city was more prompt, and, therefore, even severely injured patients could be quickly sent to hospitals for treatment. We recognized the significant difference in the time to treatment and CT scans between the earthquake and non-earthquake groups. Thus, the mortality for the earthquake group was lower because some severely injured patients died before arriving at the hospital, and there were more patients with severe injuries in the non-earthquake group, although some died eventually.Understanding the difference between head traumas caused by earthquake- and non-earthquake-related traumas is helpful for directing the specific diagnosis and treatment of injuries after an earthquake. As demonstrated in our study, patients in the non-earthquake group had more serious and complex head injuries. To diagnose their injuries, it was necessary to have them undergo CT examinations as quickly as possible. Treatment in the aftermath of an earthquake presents a special problem. The patient load in a local area will suddenly increase, resulting in a sudden excess demand for CT scanning for head traumas and other injuries. Under these conditions, selecting the patients who need urgent treatment will help improve the survival rate and optimize the use of limited medical resources. This study suggests that patients with suspected maxillofacial fractures have the greatest risk of intracranial injuries and, therefore, might deserve priority among head injury patients.MDCT to examine the head is advantageous in an earthquake because it can save scanning time. The diagnosis is rapid, which will shorten the time required for lifesaving treatment.<a class="elsevierStyleCrossRef" href="#bib20">20</a> Additionally, high-quality MPR images can demonstrate extra-intracranial injuries accurately and thoroughly and exclude the obvious intracranial injuries.<a class="elsevierStyleCrossRefs" href="#bib21">21–23</a> Furthermore, patients with head traumas present with varying levels of consciousness. However, physical examinations cannot accurately depict the extent of severe trauma. In such conditions, the CT examination is quite necessary and remains the initial diagnostic modality of choice.One limitation of this study should be mentioned again. Some of the patients with serious head traumas died before rescue workers could bring these patients to our university hospital. The Sichuan earthquake, the epicenter of which was 92 km (57 miles) from the hospital, damaged much of the infrastructure in the area, hampering rescue efforts directed to these outer suburban areas. The results of our study only address the patients who were stable enough to have survived the rescue effort and transport. Although we could not evaluate the injuries of the victims who died in the earthquake, the study of the survivors' injuries is more meaningful and reflects how we can make an actual difference in an earthquake's aftermath. Delayed rescue is common after a massive earthquake, and studying injuries in these conditions provides our medical teams with the practical knowledge that they will need to respond.CONCLUSIONIn the present study, we determined the features of earthquake-related head traumas by comparing the CT findings of head injuries caused by the Sichuan earthquake and by typical, non-earthquake-related events. Compared with non-earthquake-related head traumas, the severity of earthquake-related traumas in survivors, as depicted on CT, was milder, and isolated extracranial injuries were more frequent, which may have been the result of the different injury causes, mechanisms and settings. A comparative study of the features of earthquake-related head injuries is helpful for understanding this common condition in such a special setting."

We aim to compare the features of head traumas caused by the Sichuan earthquake with those of other common head traumas using multidetector computed tomography. METHODS:In total, 221 patients with earthquake-related head traumas (the earthquake group) and 221 patients with other common head traumas (the non-earthquake group) were enrolled in our study, and their computed tomographic findings were compared. We focused the differences between fractures and intracranial injuries and the relationships between extracranial and intracranial injuries. RESULTS:More earthquake-related cases had only extracranial soft tissue injuries (50.7% vs. 26.2%, RR = 1.9), and fewer cases had intracranial injuries (17.2% vs. 50.7%, RR = 0.3) compared with the non-earthquake group. For patients with fractures and intracranial injuries, there were fewer cases with craniocerebral injuries in the earthquake group (60.6% vs. 77.9%, RR = 0.8), and the earthquake-injured patients had fewer fractures and intracranial injuries overall (1.5±0.9 vs. 2.5±1.8; 1.3±0.5 vs. 2.1±1.1). Compared with the non-earthquake group, the incidences of soft tissue injuries and cranial fractures combined with intracranial injuries in the earthquake group were significantly lower (9.8% vs. 43.7%, RR = 0.2; 35.1% vs. 82.2%, RR = 0.4). CONCLUSION:As depicted with computed tomography, the severity of earthquake-related head traumas in survivors was milder, and isolated extracranial injuries were more common in earthquake-related head traumas than in non-earthquake-related injuries, which may have been the result of different injury causes, mechanisms and settings."

male patients were also more common in the non-earthquake group than in the earthquake group&#46; These differences were consistent with previous reports&#46;<a class="elsevierStyleCrossRefs" href="#bib9">9&#44;10</a> This difference possibly reflects the tendency of young and middle-aged male patients to engage in riskier social behaviors&#46;</p><p id="para150" class="elsevierStylePara elsevierViewall">We found that head traumas caused by the earthquake were possibly different from head traumas with other causes&#46; Patients in the earthquake group had fewer overall fractures and intracranial injuries&#46; Additionally&#44; the earthquake group had more cases with extracranial soft tissue injuries&#44; but fewer of these injuries coexisted with intracranial injuries&#46; Finally&#44; the extracranial injuries&#44; especially the soft tissue injuries and cranial fractures&#44; had a lower incidence of combined intracranial injuries in the earthquake group&#46; Additionally&#44; patients with head traumas in the earthquake group had fewer combined injuries&#46; Generally&#44; the earthquake-related head injuries as depicted on CT were less serious&#46;</p><p id="para160" class="elsevierStylePara elsevierViewall">Differences between the head traumas caused by the earthquake and other common traumas had a possibly direct relationship with the severity of the injuries&#46; In an earthquake&#44; head traumas commonly result from building collapses and falling objects&#44;<a class="elsevierStyleCrossRefs" href="#bib2">2&#44;11&#8211;14</a>&#44; whereas non-earthquake-related traumas are frequently caused by traffic accidents and falls&#46;<a class="elsevierStyleCrossRefs" href="#bib4">4&#44;10&#44;15&#44;16</a> The energy of impact is significantly different between these two settings&#44; and high-mass&#44; low-velocity injuries may be more common among earthquake-related injuries than among non-earthquake injuries&#46; In addition&#44; patients in an earthquake have a little time to react to falling buildings&#46; However&#44; patients in traffic accidents or who have fallen are even more vulnerable&#44; because the impact is so instantaneous that they have no time to protect themselves from the trauma&#44; which perhaps makes these traumas more severe&#46; In the present study&#44; the head traumas in the earthquake group mainly resulted from building collapses&#44; and the non-earthquake-related traumas from falls and traffic collisions were more serious than the traumas in the earthquake group&#46;</p><p id="para170" class="elsevierStylePara elsevierViewall">Similarly&#44; injury mechanisms could also account for the different CT findings between earthquake-related and non-earthquake-related head traumas&#46; The crush injuries caused by building collapses do not involve notable head motion after the initial collision&#46; However&#44; everyday traumas&#44; such as those resulting from traffic collisions&#44; cause deceleration injuries&#44; which can also result in countercoup injuries from the relative motion of the brain&#46;<a class="elsevierStyleCrossRefs" href="#bib10">10&#44;17&#8211;19</a> Therefore&#44; deceleration-related brain injuries are more common in non-earthquake-related head traumas and seem to cause more complicated brain injuries&#44; such as the brain contusions and lacerations seen in this study&#46;</p><p id="para180" class="elsevierStylePara elsevierViewall">In addition&#44; external conditions may also be responsible for the differences in head traumas&#46; In the massive Sichuan earthquake&#44; traffic accidents&#44; complicated infrastructure&#44; and aftershocks all delayed rescue to the outlying areas&#44; and patients with severe injuries died before they could receive emergency services&#46; By contrast&#44; rescue in the downtown area of Chengdu city was more prompt&#44; and&#44; therefore&#44; even severely injured patients could be quickly sent to hospitals for treatment&#46; We recognized the significant difference in the time to treatment and CT scans between the earthquake and non-earthquake groups&#46; Thus&#44; the mortality for the earthquake group was lower because some severely injured patients died before arriving at the hospital&#44; and there were more patients with severe injuries in the non-earthquake group&#44; although some died eventually&#46;</p><p id="para190" class="elsevierStylePara elsevierViewall">Understanding the difference between head traumas caused by earthquake- and non-earthquake-related traumas is helpful for directing the specific diagnosis and treatment of injuries after an earthquake&#46; As demonstrated in our study&#44; patients in the non-earthquake group had more serious and complex head injuries&#46; To diagnose their injuries&#44; it was necessary to have them undergo CT examinations as quickly as possible&#46; Treatment in the aftermath of an earthquake presents a special problem&#46; The patient load in a local area will suddenly increase&#44; resulting in a sudden excess demand for CT scanning for head traumas and other injuries&#46; Under these conditions&#44; selecting the patients who need urgent treatment will help improve the survival rate and optimize the use of limited medical resources&#46; This study suggests that patients with suspected maxillofacial fractures have the greatest risk of intracranial injuries and&#44; therefore&#44; might deserve priority among head injury patients&#46;</p><p id="para200" class="elsevierStylePara elsevierViewall">MDCT to examine the head is advantageous in an earthquake because it can save scanning time&#46; The diagnosis is rapid&#44; which will shorten the time required for lifesaving treatment&#46;<a class="elsevierStyleCrossRef" href="#bib20">20</a> Additionally&#44; high-quality MPR images can demonstrate extra-intracranial injuries accurately and thoroughly and exclude the obvious intracranial injuries&#46;<a class="elsevierStyleCrossRefs" href="#bib21">21&#8211;23</a> Furthermore&#44; patients with head traumas present with varying levels of consciousness&#46; However&#44; physical examinations cannot accurately depict the extent of severe trauma&#46; In such conditions&#44; the CT examination is quite necessary and remains the initial diagnostic modality of choice&#46;</p><p id="para210" class="elsevierStylePara elsevierViewall">One limitation of this study should be mentioned again&#46; Some of the patients with serious head traumas died before rescue workers could bring these patients to our university hospital&#46; The Sichuan earthquake&#44; the epicenter of which was 92 km &#40;57 miles&#41; from the hospital&#44; damaged much of the infrastructure in the area&#44; hampering rescue efforts directed to these outer suburban areas&#46; The results of our study only address the patients who were stable enough to have survived the rescue effort and transport&#46; Although we could not evaluate the injuries of the victims who died in the earthquake&#44; the study of the survivors&#39; injuries is more meaningful and reflects how we can make an actual difference in an earthquake&#39;s aftermath&#46; Delayed rescue is common after a massive earthquake&#44; and studying injuries in these conditions provides our medical teams with the practical knowledge that they will need to respond&#46;</p></span><span id="cesec140" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="cestitle190">CONCLUSION</span><p id="para220" class="elsevierStylePara elsevierViewall">In the present study&#44; we determined the features of earthquake-related head traumas by comparing the CT findings of head injuries caused by the Sichuan earthquake and by typical&#44; non-earthquake-related events&#46; Compared with non-earthquake-related head traumas&#44; the severity of earthquake-related traumas in survivors&#44; as depicted on CT&#44; was milder&#44; and isolated extracranial injuries were more frequent&#44; which may have been the result of the different injury causes&#44;
