Exposing the culprit: Triquetrohamate impaction syndrome as a cause of refractory ulnar-sided wrist pain

Ulnar-sided wrist pain is a common presentation with complex diagnostic challenges. The diagnostic challenges are due to the complexity of anatomical organization and the histological diversity within a small anatomical region. In this case report, we present a case of triquetrohamate impaction syndrome, an uncommon cause of ulnar-sided wrist pain with an emphasis on the role of imaging. The case involves a 27-year-old female clerk with persistent wrist pain, revealing significant findings on magnetic resonance imaging, including reduced triquetrohamate joint space, associated bone marrow edema, and degenerative changes. Our patient had a good clinical response to conservative management. It is essential that the clinicians and radiologists possess adequate knowledge and awareness regarding triquetrohamate impaction syndrome for early diagnosis and treatment.
