Diagnosis of ulnar-sided wrist pain: a pragmatic approach for the non-specialist

Ulnar-sided wrist pain is often unfairly labelled as the 'back pain' of the wrist. This reputation comes from the complexity of diagnosing problems related to this area of the wrist. This article summarizes the anatomy and biomechanics of the wrist and presents a logical approach to diagnosing the aetiology of the pain. The problems are categorised based on the anatomical structure from which the pain arises: either bony, soft tissue-related or arising from nerves or vascular structures. The article also outlines the relevant examination findings and the most appropriate investigation that would yield a diagnosis with any given presentation.
