Final answer:
The statement is false because the Abbreviated Injury Scale (AIS) assigns unique identifiers to different types of injuries, and closed fractures and NFS (not further specified) fractures would have distinct 7-digit codes due to their different characteristics and severity.
Step-by-step explanation:
True or False: Closed and NFS fractures share the same 7 digit AIS numerical identifier?
This statement is False. The Abbreviated Injury Scale (AIS) provides unique numerical identifiers for coding different types of injuries. Closed fractures and NFS (not further specified) fractures typically would not share the same 7-digit AIS code because the AIS system is designed to reflect the type and severity of the injury, and these details would differ between a closed fracture (where the skin is not broken) and an NFS fracture, which lacks specific information on the type of fracture presented.
In the AIS system, every injury is detailed according to various aspects such as region of the body, the type of injury, and its severity. These details are reflected in the numerical identifier, which is why two differently characterized fractures such as closed and NFS would have distinct identifiers.
