The scaphoid is the most commonly fractured carpal bone, accounting for approximately 68 % of all carpal fractures. Triquetral fractures are the second most common carpal bone fracture and are usually ligamentous avulsion fractures. The aim of this paper is to report the co-existence of scaphoid and triquetral fractures with an adult patient. Case: A twenty one years old man was admitted to the emergency department after falling on an outstretched hand. He was complaining about a mild pain in his wrist. There was swelling and tenderness of the anatomic snuff box and ulnar aspect of wrist, decreased range of motion in flexion and extension. X-ray showed fractures at both scaphoid and triquetral bones. Computed tomography showed that proximal fracture of scaphoid and fracture at triquetral body. The scaphoid fracture was treated with internal fixation and any complication was not observed. Conclusion: Triquetral fractures are associated with carpal instability and there is an increased risk of avascular necrosis for scaphoid fractures. Emergency physicians should be careful at wrist injuries because of accompanied unclear fractures.
