Correct answer: E — Reduce under procedural sedation, then obtain CT after reduction

The best answer is “Reduce under procedural sedation, then obtain CT after reduction”. Native hip dislocation is an orthopedic emergency. With no suspected femoral-neck fracture, prioritize reduction—normally within six hours—to reduce avascular-necrosis risk, then obtain CT to identify loose bodies and acetabular or femoral-head injury. Pre-reduction CT, delayed reduction, discharge or exercises postpone restoration of blood supply and congruity.
