Which term describes a high-energy injury with leg deformity?

• A. Posterior Hip Dislocation
• B. Anterior Hip Dislocation
• C. Traumatic Shock
• D. Hip Dislocation

Answer: (D)

A high-energy trauma with a leg deformity points to a hip dislocation. In this injury, the femoral head is displaced from the acetabulum, typically after a powerful force such as a motor vehicle crash. The leg deformity comes from the misalignment of the femur with the pelvis, which is the hallmark feature of a dislocation. The two specific forms—posterior and anterior hip dislocations—are subtypes of this injury, but the general term hip dislocation best fits the description because it encompasses the injury mechanism and presentation without specifying direction. Traumatic shock describes a systemic response to severe injury, not the limb injury itself, so it isn’t the term that describes the described presentation.
