Which of the following groups of bones could be involved in a patient with a "broken leg"?

The group of bones that includes the femur, tibia, and fibula is indeed involved in what is commonly referred to as a "broken leg." This terminology typically pertains to fractures in the lower extremity, specifically the long bones of the leg.

The femur is the thigh bone, the strongest and longest bone in the body, while the tibia and fibula are the two primary bones of the lower leg. Fractures can occur in any of these bones due to trauma, falls, or accidents, leading to pain, swelling, and dysfunction in leg movement.

Understanding the anatomy is crucial because it helps in identifying the type and extent of injury when assessing a leg fracture. The other groups listed—bones of the arm and shoulder or those in the wrist and hand—are not involved in a "broken leg" situation, as they pertain to different regions of the body. Thus, the femur, tibia, and fibula are the relevant bones in this context.
