A 25 y/o gymnast presents to the ED after missing a high bar and falling on her outstretched left hand. She complains of pain and swelling at the elbow. On exam she has no tenderness at the snuffbox or distal radius with normal active ROM of the wrist, but is tender on both the medial and lateral elbow with obvious swelling around the elbow and limited active ROM. Neurovascular exam reveals decreased sensation to the tip of 5th digit. X-ray reveals a joint effusion without a fracture or dislocation. What is the most likely diagnosis?
