Which of the following injuries might require immediate reduction in a wilderness setting?

Immediate reduction is a critical intervention for certain types of injuries, particularly dislocations. In this case, a dislocation of the shoulder often requires immediate attention to alleviate pain and restore the normal anatomy of the joint. If left unreduced, a dislocated shoulder can lead to complications such as impaired circulation, nerve damage, or persistent joint instability.

The promptness in addressing a shoulder dislocation in a wilderness setting is essential, as this type of injury can cause significant discomfort and limit mobility for further action or evacuation. Quick reduction can effectively alleviate pain and prevent potential complications.

Other injuries, such as fractures of the femur, while serious, typically require stabilization before transportation or more advanced care can be arranged, making immediate reduction less critical. Similarly, sprained ankles and burns, while needing attention, do not normally necessitate immediate intervention like reduction, focusing instead on pain management and preventing further injury.
