Acute shoulder trauma: what the surgeon wants to know. Sandstrom CK(1), Kennedy SA, Gross JA. Author information: (1)From the Department of Radiology (C.K.S., J.A.G.) and Department of Orthopedics and Sports Medicine (S.A.K.), University of Washington, 325 Ninth Ave, Box 359728, Seattle, WA 98104. Many excellent studies on shoulder imaging from a radiologic perspective have been published over the years, demonstrating the anatomy and radiologic findings of shoulder trauma. However, it may not always be clear what the surgeon, who bears the responsibility for treating the injured patient, really needs to know about the injury to predict outcomes and plan management. The authors review the relevant osseous, soft-tissue, and vascular anatomy and describe the clinically relevant concepts that affect management. Familiarity with the Neer classification system for proximal humerus fractures can have a significant impact on treatment. The length and displacement of the medial humeral metaphyseal fragment helps predict the risk of ischemia in proximal humerus fractures. The Nofsinger approach for measuring the area of glenoid fossa bone loss can help the surgeon determine the need for surgical repair of a bony Bankart lesion. The size of Hill-Sachs and reverse Hill-Sachs lesions is also an important predictor of stability. The Ideberg classification system for intraarticular fractures of the glenoid fossa, combined with information on instability and joint incongruity, helps determine the need for surgical fixation of glenoid fossa fractures. Awareness of what matters to the surgeon can help radiologists better determine where to focus their attention and efforts when describing acute shoulder trauma. (©)RSNA, 2015.
