Background
Tendinous and ligamentous injuries can have varying severity and implications, and yet despite this, many have fairly benign radiographic appearances or may look similar to more benign injuries. Knowing how to recognize injuries that should not be missed and which injuries are important to follow up with additional imaging (such as MRI or ultrasound) is important in identifying such pathology early enough to still treat effectively.

Educational Goals / Teaching Points
The goals of this exhibit are to identify several seemingly inconsequential types of avulsion injuries in the extremities on plain radiography; compare and contrast similar appearing avulsion fractures; understand the underlying mechanism and tendon/ligament involved; and familiarize key features of each injury for reporting purposes, when to offer further imaging, and planned intervention.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
For each seemingly inconsequential injury, we will discuss the anatomy, tendon/ligament involved, key features to mention in reports, features on plain radiography and cross-sectional imaging, and the intervention required. The exhibit will review gamekeeper’s thumb (ulnar collateral ligament and Stener lesion); radial collateral ligament of the thumb; Bennet fracture vs Rolando fracture; mallet finger vs jersey finger; triquetral fracture vs extensor carpi radialis longus/brevis avulsion; Segond fracture vs reverse Segond fracture; Stener-like lesion of the knee; and Jones fracture vs pseudo-Jones fracture.

Conclusion
In reviewing a variety of tendinous and ligamentous injuries with important pathologic implications that often require further imaging, participants in this educational exhibit will be able to reinforce important concepts related to involved anatomy, proper reporting, key features on plain radiography and cross-sectional imaging, and what/why intervention is required.
