<div>HISTORY:&#160;This 43-year-old female presents with pain and decreased range of motion of left elbow after a fall and hyperextension of elbow four days prior.(QUIZ ANSWER) ALSO A FINDING IN THIS CASE:&#160;All of the above.Using the&#160;diagnostic web viewer, we have provided images that assist in telling our clinical story. Areas of significance are indicated below.FINDINGS: Large depressed capitellar fracture with moderate-sized elbow hemarthrosis. Fracture is located along the back of the capitellum, a sign of an elbow dislocation and Osborne-Cotterill fracture.In addition, small peel-like tear of the medial collateral ligament distally at the insertion on the tubercle.Furthermore, partial thickness tear of the proper collateral ligament proximally.&#160;Posteriorly, lateral ulnar collateral ligament is torn from its origin, full-thickness.Lower grade radial collateral ligament proper tear.Distal separation of the ulnar collateral ligament from the sublime tubercle.Capsule remains intact.Brachialis is intact.&#160;Coronoid is intact.&#160;Ulnar nerve is unaffected, however mild compression due to surrounding edema.CONCLUSION:Osborne-Cotterill fracture of the capitellum with full-thickness lateral ulnar collateral ligament tear at the origin, medial collateral ligament insertion peel-like tear distally, partial thickness tear of the proper collateral ligament, and low grade radial collateral ligament proper tear.&#160;Associated moderate-sized hemarthrosis.&#160;Findings consistent with posterolateral elbow dislocation.&#160;Intact capsule, brachialis, and coronoid.</div>
