"The trapezoid articulates with the scaphoid, capitate, trapezium and the base of the second metacarpal."
"The dorsal intercarpal and basal metacarpal arches, as well as the radial recurrent artery, provide the vascularity of the trapezoid. Vessels enter through both the central dorsal and palmar surfaces. The dorsal vessels provide the primary vascularity, the dorsal 70% of the bone. There are no anastomoses between the dorsal and palmar surface entering vessels."
