Fig. 8B 32-year-old-man injured by bone fragments. Bone fragments may
become projectiles themselves and cause severe penetrating injury. They can
become necrotic debris and serve as nidus for infection. Bone fragments may
test positive for hepatitis B virus (HBV) and HIV. Axial (A) and
coronal (B) reconstruction CT images show bone fragment injuries in
right neck (arrow, A).
