Final answer:
The humerus, forearm, femur, tibia, and pelvis are managed with an external fixator.
Step-by-step explanation:
The humerus in the upper arm, the forearm which includes the radius and ulna bones, the femur in the thigh, the tibia in the lower leg, and the pelvis are managed with an external skeletal fixator called an external fixator. This fixation device is used to stabilize and support fractured bones by using metal pins or screws that are inserted into the bones and connected to an external frame.
