Purpose The purpose of this study was to investigate the intraosseous vascular anatomy of
the scaphoid using recent advances in micro–computed tomography (micro-CT) imaging
and 3-dimensional reconstruction. We also studied the effect of scaphoid shape and screw
position on the intraosseous vascular structure. Methods Thirteen upper extremities were
injected with a contrast agent. The scaphoid bones were extracted and scanned using a
micro-CT scanner. The vascular impact of screw insertion at various axes through the …

Purpose To study the intraosseous 3-dimensional microvasculature of the capitate bone
using a novel high-resolution micro-computed tomography (μCT) imaging technology, and
to examine the blood supply as it relates to the most common fracture types. Methods Ten
cadaveric wrists were injected with a lead-based contrast agent. The capitates were
harvested and imaged using a μCT scanner. The intraosseous vascularity was incorporated
into a 3-dimensional image. We measured the vascular pattern as well as the vessels' cross …
