Abstract
Triquetral, or pyramidal, bone fractures are the second most common carpal fracture after scaphoid fractures. They usually result from bone impaction after extension trauma and ulnar deviation of the wrist. These fractures are classified into three groups: triquetral dorsal cortical, body, and volar cortical fractures. The late diagnosis of these injuries is not uncommon since they may go unnoticed during care at the Emergency Services. The early performance of additional radiological tests, such as computed tomography (CT), may avoid late diagnoses. Classically, these fractures have a good prognosis, and their treatment is immobilization. However, magnetic resonance imaging (MRI) can help the diagnosis of associated lesions in cases of poor evolution. The recent literature discusses the different types of surgical procedures available depending on the presence of carpal instability, fibrous pseudoarthrosis, triangular fibrocartilage complex injuries, pisotriquetral arthrosis, etc. The objectives of this study are to compare clinical cases in two distinct profiles of patients presenting the same injury but different evolution and to carry out a complete review on the subject, providing additional information on some triquetral fracture complications.
