Chronic wrist pain presents a diagnostic challenge, demanding a comprehensive understanding of its multifactorial etiology. This case report focuses on wrist coalition, an infrequent orthopedic condition characterized by abnormal articulations between carpal bones, often associated with prolonged wrist discomfort. A 45-year-old man with a two-year history of persistent left wrist pain, with no previous history of trauma or systemic illness, had a localized tenderness in the left carpal region with a restricted range of motion, and diminished grip strength on physical examination. Initial investigations, including autoimmune profiles and plain radiographs, were inconclusive. Magnetic resonance imaging ultimately identified a coalition between the capitulum and the trapezoid. A multidisciplinary team recommended a conservative approach, resulting in a positive response and symptomatic improvement during follow-up. This case report contributes valuable insights to the limited literature on isolated capitulum and trapezoid coalition, highlighting the significance of considering such rare orthopedic entities in the comprehensive evaluation of chronic wrist pain.
Keywords: capitulum; carpal coalition; chronic wrist pain; syndesmosis; trapezoid.
