title: Current Concepts of the Carpal Boss: Pathophysiology, Symptoms, Clinical or Imaging Diagnosis, and Management.
abstract: The carpal boss reflects an osseous protuberance at the level of the dorsal base of the second or third metacarpal, variably present in the general population. There are numerous theories as to the etiology of the bony excrescence; however, the exact cause remains uncertain. The abnormality can result in dorsal wrist pain and swelling. The diagnosis is typically established based on clinical examination and imaging, including radiography, ultrasound, nuclear medicine, computed tomography, and magnetic resonance imaging. We review the proposed theories of how the carpal boss develops, explain the clinical manifestations, demonstrate the imaging appearance, and address treatment strategies.
