Evaluation of Four-Dimensional Computed Tomography as a Technique for Quantifying Carpal Motion.

J Biomech Eng 2021 Jun;143(6)

School of Biomedical Engineering, Western University, 1151 Richmond St, London, ON N6A 3K7, Canada; Roth McFarlane Hand and Upper Limb Centre, St Joseph's Health Care London, 268 Grosvenor St, London, ON N6A 4V2, Canada.

Delayed diagnosis of dynamic carpal instability often occurs because early changes in bone alignment and movement are difficult to detect and manifest mainly during a dynamic/functional task. Current diagnostic tools are only able to examine the carpal bones under static or sequential-static conditions. Four-dimensional (three dimensions + time) computed tomography (4DCT) enables quantification of carpal mechanics through 3D volume sequences of the wrist in motion. Read More

[Fractures of the carpal bones without the scaphoid bone].

Unfallchirurg 2021 Jan;124(1):59-73

Abteilung für Handchirurgie, Vulpius Klinik, Vulpiusstr. 29, 74906, Bad Rappenau, Deutschland.

With the exception of the relatively frequent fractures of the scaphoid bone, isolated fractures of individual carpal bones are rare. Because these injuries are uncommon and because of the complex anatomy and function of the carpus, treatment of carpal bone fractures can be challenging. Carpal bone fractures generally occur in young, sports active and professional patients, can be easily overlooked in plain radiographs and are frequently associated with ligamentous instability, neurovascular injuries and tendon lesions.
