title: Trispiral tomography for the evaluation of wrist problems.
abstract: Trispiral tomography is an x-ray technique that is essential in the diagnosis and management of a wide variety of problems involving the carpal bones and their joints. It facilitates the visualization of acute fractures, particularly those of the scaphoid and hook of the hamate, as well as cysts, sclerosis, and erosive lesions. It is useful in differentiating between acute and chronic changes, and it is often indispensable in evaluating healing after acute fractures or bone grafts to treat nonunions.
