Diagnosing ulnar-sided wrist pain can be challenging due to the proximity of numerous anatomical structures that can all be injured, which cause pain or produce mechanical instability. Understanding the anatomy of the ulnar side of the wrist and the biomechanics of normal and dysfunctional movement are essential to accurate diagnosis and effective treatment.
Triangular fibrocartilage complex—important but not the only culprit
So far the commonest presumptive diagnosis for ulnar-sided wrist pain has been triangular fibrocartilage complex (TFCC) injury. Though this may prove to be true the TFCC is not the only cause of pain around the ulnar side of the wrist. The rise in knowledge of the TFCC has been driven by an expanding body of research into this complex structure. A MEDLINE search for the term TFCC revealed no results until 1979, in the years 1980–1987 there were only six articles, this rose to 47 from 1988 to 1995 and between 1996 and now 244 articles have come into view. However, other causes of ulnar-sided wrist pain should not be overlooked. The purpose of this editorial is to give the reader a framework of basic science with which to approach this problem and to link in …
