ABSTRACT
OBJECTIVES@#To explore the influencing factors of the horizontal distance of bodies in the high falling scene and the feasibility of inferring the falling mode based on it.@*METHODS@#A total of 614 high falling deaths and 15 cases of corpse dumping from high altitudes were collected. The relationship between the horizontal distance and the falling height, as well as the sex, age and manner of death (suicide, accident and corpse dumping) were observed.@*RESULTS@#The horizontal distance increased with the increase of falling height, and the difference among the height groups was statistically significant. The horizontal distance decreased with the increase of the age of the deceased, in each height group, the difference between the group over 60 years old and other age groups was statistically significant (P<0.05). The horizontal distance of male deceased was (1.99±0.27) m, which was greater than that of female deceased (1.88±0.19) m, and the difference was statistically significant in partial height groups (P<0.05). Roof falls had a greater horizontal movement distance than window falls. Except for the >20-30 m group, there was no significant difference in horizontal distance between suicide high falls and accidental high falls in other height groups.@*CONCLUSIONS@#The horizontal distance is affected by the falling height, the sex and age of the victim, and the spatial characteristics of the falling starting point.

ObjectiveTo analyze the relationship between the factors causing thoracolumbar burst fracture and the corresponding clinical manifestations, so as to improve the early warning and diagnosis of thoracolumbar burst fracture, reduce the misdiagnosis and missed diagnosis, and improve the success rate of first aid. MethodsThe clinical data of thoracolumbar burst fractures treated in the Intensive Care Unit of Depretment of Emergency of our hospital from Jan. 2009 to Dec. 2018 were retrospectively analyzed. The clinical data, including age, sex, hospital duration, causes, complications, discharge, and prognosis, were analyzed retrospectively. Results A total of 83 patients with thoracolumbar burst fracture, including 69 males (83.13%) and 14 females (16.87%), were selected for this study. The average age was (44.64±15.26) years. The causes of the injury included: High falling injury (53 cases, 63.86%), traffic accident injury (17 cases, 20.48%), and heavy object injury (12 cases, 14.46%). There were 31 cases (37.35%) of craniocerebral injury, 53 cases (63.86%) of chest injury, 37 cases (44.58%) of abdominal injury, 44 cases (53.01%) of other fracture. Among the 53 cases of chest injury, there were 19 cases (35.85%) with hemopneumothorax, 13 cases (13.21%) with simple hemothorax, 7 cases (24.53%) with simple pneumothorax, 8 cases (15.09%) with mediastinal hemorrhage, 7 cases (13.21%) with mediastinal emphysema, 11 cases (20.75%) with flail chest, and 5 cases (9.43%) with diaphragmatic hernia. Among 37 cases of abdominal injuries, there were 8 cases (21.62%) with rupture of spleen, 3 cases (8.11%) with subcapsule hematomas, and 4 cases (10.81%) with simultaneous injury of liver and spleen. The missed diagnoses at the initial diagnosis included: 5 cases (100.00%) of diaphragmatic hernia, 5 cases (62.50%) of mediastinal hemorrhage, 4 cases (57.14%) of mediastinal emphysema, 2 cases (18.18%) of flail chest, and 2 cases (15.38%) of simple hemothorax. Missed diagnosis rate of the other complications were all under 10.00%. The main complications were bronchopneumonia (37 cases, 44.58%) and traumatic hemorrhagic shock (17 cases, 20.48%). There were 8 cases (9.64%) complicated with multiple organ dysfunction syndrome (MODS), with more than 3 systems involved. There were 39 patients (46.99%) had paraplegia and 3 cases (3.61%) died at discharge. ConclusionThoracolumbar burst fractures are more common in young and middle-aged men, with high falling being the primary cause and hemopneumothorax being the main clinical manifestation. Diaphragmatic hernia, mediastinal hemorrhage and mediastinal emphysema are easy to have missed diagnosis. Nearly 50% patients have traumatic paraplegia, which is worthy of attention and in-depth study.
ABSTRACT
Objective To explore the relation between the behavior psychology analysis of partial me-chanical injuries and the nature of death in high-falling cases, and provide reference, for such cases. Methods Of 311 death victims of high-falling injuries collected from 2008 to 2013, 205 cases were as-sociated with partial mechanical injuries. The characteristics of injury formation, preliminary crime scene traces, fatal injury of high-falling, and text messages were all retrospectively analyzed. Results Accord-ing to the investigation of preliminary crime scene traces, fatal injury of high-falling and text message, there were 86 suicide, 24 accident and 95 uncertainty in the 205 cases. According to the behavior psy-chology analysis of partial mechanical injuries, there were 80 suicide, 11 accident, and 4 homicide in the 95 uncertainty cases. Conclusion The partial mechanical injuries uncertainly caused by high-falling correlate with the manner of high-falling death. According to the behavior psychology analysis of the partial mechanical injuries in high-falling death cases, the presumption of high-falling death is usually accurate.
