【Abstract】 Objective To explore the characteristics and law of limb trauma caused by steel ball shells and giving a basis of treating explosive limb trauma. Methods The wound effects of steel ball shells injuries to limbs of sheep were observed in the field. Results 53.3% of sheep died immediately after injury, and mortality reached to 70.6% at 6h after explosion. Morbidity of limbs injury was 56.7%, 66.7% of the soft tissue injury was occurred among those traumatized on the limbs. Morbidity of fracture was 23.3%, and they were all comminuted fracture. Combined injury was most often occurred on the thorax and abdomen, and the incidence of them was 70.6% and 64.7%. Conclusion The incidence of limb injury hit by fragments is high, and the wounding is serious, fractures are all comminuted fracture and combined with multiple injuries is more.更多还原
