Diagnose on Sight: Post-traumatic Finger Pain
Case: A 32-year-old male with a past medical history of diabetes presents with a 1 month history of finger pain after slamming his finger in a car door. 2 weeks after the initial incident he presented to the emergency department for worsening pain and received x-rays that were negative for acute fracture. Today he presents reporting pain radiating up the hand, arm, and into the shoulder, with associated chills. His labs are significant for hyperglycemia, hyponatremia, and an elevated erythrocyte sedimentation rate and c-reactive protein. His x-ray is seen here (figure 1 image courtesy of Daniel Rogan, MD).

Radiology teaching during medical school is variable, ranging from informal teaching to required clerkships [1]. Many of us likely received an approach to a chest x-ray, but approaches to other studies may or may not have not been taught. We can do better! Enter EM:Rad, a series aimed at providing “just in time” approaches to commonly ordered radiology studies in the emergency department. When applicable, it will provide pertinent measurements specific to management, and offer a framework for when to get an additional view, if appropriate. We recently covered the 
Two patients present to your emergency department: Patient 1 is a 17 year-old soccer player who fell during a game onto their right side and is now complaining of mild right shoulder pain. You obtain x-rays (Figure 1). Patient 2 is a 21 year-old motorist who lost control and went over the handlebars. They heard a pop and are complaining of left shoulder pain. You obtain shoulder x-rays (Figure 2). For these cases, what are your diagnoses, expected physical examination findings, and emergency department management?
