Trajectories and resultant severity and pattern of injury can vary widely with both stab and gunshot wounds. Hemodynamically unstable patients need immediate operative intervention. Mechanism and time of injury, weapon characteristics, and determining the bullet path or stab wound depth may also assist in determining the initial diagnostic approach if the patient is otherwise stable.
