Abstract

This study examined patterns of bone mineral density (BMD) of the wrist by computed tomography–absorptiometry to evaluate force transmission patterns in vivo in patients with complaints of wrist instability requiring lunate-capitate-triquetrum-hamate (LCTH) arthrodesis. These patterns represent long-term force transmission through the wrist joint because BMD differs under different loading conditions. BMD studies of the wrist joint in vivo can evaluate the long-term force transmission through the joint under physiological and pathological conditions and before and after wrist surgery. The scaphoid fossa is relatively unloaded after LCTH arthrodesis, and a decrease in BMD is observed in the lunate fossa.
