To build three-dimensional (3-D) visible model for surgical treatment of infection of fascial spaces of hand.
Serial thin cross-sections (0.2 mm) of hand were made by cryomicrotome, and the thin cross-sections of metacarpal parts were observed. A personal computer was employed to reconstruct 3-D model of metacarpal fascial space.
The shapes, locations and adjacent relations of the mid-palmar space, thenar space and metacarpal bones were displayed clearly from computerized 3-D model, which could be the cross-reference of the cross-sections expediently.
The computerized 3-D reconstruction of metacarpal fascial spaces can provide some guidance for surgical treatment of infection and other diseases of metacarpal fascial spaces.
