A Pop in the Calf – Plantaris Rupture

A 32 year-old male presents to the Emergency Department after he felt a “pop” in his posterior-medial calf while playing tennis. He was able to ambulate but had pain with plantar flexion and was unable to continue playing tennis. What is your differential diagnosis? What physical exam maneuver would you perform? What findings would you expect on physical exam? What is the diagnosis based on ultrasound images? What is your management in the emergency department?

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). What is the diagnosis?

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
