Background
The purpose of this educational exhibit is to review the relevant anatomy and present a multimodality review of common and important traumatic injuries of the wrist and hand.

Educational Goals / Teaching Points
- Review important anatomic considerations when reviewing the wrist and hand. - Discuss traumatic osseous injuries of the wrist and hand including distal radioulnar joint dislocation/subluxation, lunate & perilunate dislocation, Smith’s fracture, Barton’s fracture, Colles’ fracture, scaphoid fracture, mallet Finger, jersey Finger and others. - Discuss soft tissue injuries of the wrist and hand including triangular fibrocartilage complex tears, scapholunate and lunotriquetral ligament tears and instability, UCL Injuries of the thumb and Stener lesions, flexor and extensor tendon lacerations, volar plate avulsion injury, and pulley injuries. - Review the role of US and MRI in diagnosis and treatment of wrist and hand injuries.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
Triangular Fibrocartilage Complex Tears, UCL Injuries, Volar plate avulsion injury, Pulley injuries, Gamekeeper Thumb and Stener Lesions, Scaphoid fracture, Perilunate dislocation, Scapho-lunate instability, lunotriquetral instability, Distal radioulnar Joint Dislocation/Subluxation, Flexor and extensor tendon laceration, Smith’s fracture, Barton’s fracture, Colles’ fracture, Chauffeur fracture, Mallet Finger, Jersey Finger, Coach finger, Seymour fracture

Conclusion
The range of wrist and hand injury patterns is wide, and each injury pattern has its own unique imaging, diagnostic, and treatment considerations. Radiologists with a strong understanding of wrist and hand anatomy and knowledge of common wrist and hand injuries are best prepared to make accurate diagnoses and guide appropriate treatment.
