Background
Skiing, snowboarding, and snowmobiling are among the most popular winter sports in the United States. These activities can result in a wide variety of injuries. Understanding the mechanics of various winter activities can bolster the radiologist’s ability to correctly diagnose the commonly seen injuries. The goal of this exhibit is to highlight and expedite diagnosis of injuries commonly associated with winter sports.

Educational Goals / Teaching Points
This exhibit aims to aid in the understanding of anatomically significant structures for evaluation of winter sport trauma. In addition, we will discuss common and less common mechanisms of injury in winter sports. And we will review co-occurring traumatic injuries and discuss the best modalities of imaging for further evaluation.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
Skiing injuries are varied and may include the upper or lower extremities. In this review, we will present varied skeletal and tendon/ligamentous injuries which include torn anterior cruciate ligament, “skiers’ thumb,” avulsion of the proximal adductor longus tendon, tear of the myotendinous junction of the gastrocnemius, and more. These injuries will be discussed by their findings on radiograph, CT, ultrasound, and MRI. In snowboarding, upper extremity injuries are common, with wrist fractures occurring most frequently. A detailed discussion of upper extremity injuries seen on radiograph, CT and MRI will be included. Additionally lower extremity injuries such as “snowboarder’s fracture” or lateral talar process fracture will be addressed. A wide variety of traumatic injuries associated with snowmobiling will be discussed including fractures anywhere from the skull to distal lower extremities. Additional injuries including upper extremity amputation will be discussed.

Conclusion
Understanding the wide variety of injuries and the best modalities to evaluate them is key to correctly diagnosing patients.
