Wrist and Hand

The wrist and hand have complex anatomy with small bones and supporting soft tissue structures, which limits the diagnostic yield for radiologic assessment. Knowledge of anatomy and different clinical entities is key to the radiologic diagnosis. Some of the essential anatomic and clinical topics in radiologic interpretation include knowledge of the topographic tendon anatomy of wrist and hand, the intrinsic and extrinsic carpal ligaments, the thumb ligaments, thumb carpometacarpal ligaments, the triangular fibrocartilage complex, the extensor mechanism, and the flexor tendons and pulleys. In this chapter, common traumatic injuries affecting the wrist and hand are reviewed.
