A 22-year-old woman presents to the ED complaining of right elbow pain and swelling after falling off her motor scooter. On exam, she is holding the right arm in 45 degrees of flexion, and you palpate a prominent olecranon posteriorly. Radiographs reveal a posterior elbow dislocation. Which of the following statements is TRUE?
(A) The preferred method of reduction involves hyperflexion and internal rotation until a palpable reduction occurs.
(B) If full, smooth, passive range of motion (ROM) is not possible postreduction, the postreduction film should be examined for entrapment of the medial epicondyle.
(C) A long arm plaster splint should be applied in full extension and appropriate orthopedic follow-up arranged.
(D) An intact radial pulse postreduction rules out any possibility of vascular compromise.
