Abstract
The motor function of the thumb and its alignment with regard to the hand make it
particularly vulnerable to trauma. Pathology encountered in this joint is varied,
and imaging techniques play a crucial role in the diagnosis and characterization of
injury. Despite advances in imaging technology, acute thumb injuries remain a challenge
for radiologists. Currently, standard radiography and ultrasonography are frequently
used first-line imaging techniques. Computed tomography is most often indicated for
complex fractures and dislocations. Magnetic resonance imaging may be used to optimally
characterize soft tissues and bone marrow. In this article, we cover the most common
traumatic injuries: fractures, dislocations, collateral ligament injuries of the metacarpophalangeal
joint, as well as soft tissue lesions.
