Low-velocity objects usually cause penetrating injuries in the regions of the skull's temporal bones or orbital surfaces, where the bones are thinner and thus more likely to break.[1] Damage from lower-velocity penetrating injuries is restricted to the tract of the stab wound, because the lower-velocity object does not create as much cavitation.[2] However, low-velocity penetrating objects may ricochet inside the skull, continuing to cause damage until they stop moving.[3]
