Shortened and externally rotated indicates injury to which region?

• A. Shoulder
• B. Hip (femur)
• C. Wrist
• D. Knee

Answer: (B)

Shortened and externally rotated is a hallmark sign of a hip region injury, most commonly a femoral neck fracture. When the femur’s neck is fractured, the limb can no longer align with the pelvis, so it appears shortened. At the same time, the muscles crossing the hip and acting to rotate the leg outward—along with gravity—pull the femur into an externally rotated position. This combination is typical of hip fractures and helps distinguish it from injuries of other joints. In contrast, injuries to the wrist or knee don’t produce a limb that is both shortened and rotated externally in the same way, and shoulder injuries affect the upper arm rather than the leg. Hip dislocations are less likely to present this exact pattern, as posterior dislocations tend to cause internal rotation.
