Abstract
Triquetrum fractures are the second most common carpal fractures after scaphoid. However they are seldom encountered due to their clinical symptoms and since they cause less functional disability. They can be misdiagnosed as soft-tissue injuries by considering the similar localization of pain and prolonged symptoms. The majority of triquetrum fractures can be diagnosed with direct X-ray. Obtaining three plane (anterior-posterior, lateral and oblique) X-rays is especially important in diagnosing dorsal chip fractures. Accurate diagnosis provides both controlling the symptoms with adequate immobilization, sufficient information of the patient in the acute period and preventing unnecessary diagnostic work up in the subacute period because of prolonged discomfort. In our study, fifteen patients with isolated triquetrum fractures admitted within six year period were presented with their clinical, radiological features and treatment outcomes.
Highlights
Triquetrum fractures are seen together with fractures of distal radius, forearm and commonly with other scaphoid fractures or they may rarely occur in isolation
Triquetral fractures are generally classified into two groups as body fractures and dorsal chip fractures [1] and there are different views regarding mechanism of injury of triquetral fractures
It was accepted that body fractures occurred with compression mechanism and dorsal chip fractures occurred with avulsion mechanism [2] [3], but afterwards it had been suggested that dorsal chip fracture of the triquetrum was caused by the effect of ulnar styloid [1] [4] or the hamate [5] on the dorsum of the os triquetrum upon a fall on the wrist in dorsiflexion
Summary
Triquetrum fractures are seen together with fractures of distal radius, forearm and commonly with other scaphoid fractures or they may rarely occur in isolation. Due to underdiagnosis or misdiagnosis, frequently real incidence of these fractures cannot be known exactly. Diagnosis of these fractures, most of them can be successfully.

Assessment of the fracture as wrist sprain with inappropriate radiographs may cause prolongation of the patient’s complaints. Fifteen patients were presented with their clinical and radiological features to emphasize the importance of direct radiological investigation in appropriate position for diagnosis of isolated triquetrum fractures
