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

• A. Pelvic/hip EMT Care
• B. Hip Dislocation
• C. Posterior Hip Dislocation
• D. Traumatic Shock

Answer: (B)

A hip dislocation is the injury described by a high-energy event that drives the head of the femur out of the acetabulum, producing a noticeable deformity in the leg. This term covers the situation when the joint surfaces are no longer aligned, which is why it fits best for a leg deformity after significant trauma. Posterior dislocations are the most common specific type, but calling it a hip dislocation captures the general injury in EMS assessment and treatment. Pelvic/hip EMT Care is not a diagnosis, and traumatic shock refers to a systemic response rather than the joint injury itself. So the best term is hip dislocation.
