[Ulnocarpal Wrist Pain - Tips for the Daily Practice].

Introduction: Ulnar wrist pain is a frequent symptom with many possible traumatic and non-traumatic causes. The complex anatomy and biomechanics of the wrist with the ulnocarpal complex including the triangular fibrocartilaginous complex (TFCC), the distal radio-ulnar joint (DRUJ) and the ulnar carpal bones make the differentiation between the possible causes difficult. A precise clinical investigation and appropriate imaging studies are essential for detecting the most important differential diagnoses, the first therapeutical steps and an early and appropriate referral to the hand surgeon.
