Static ultrasound was used to examine the cross-sectional anatomy of the fingers principally to determine the feasibility of demonstrating the normal anatomy of the flexor tendons and also to investigate the possibility of showing pathological anatomy. The study showed that normal and pathologic anatomy of the flexor tendons could be easily demonstrated using the available ultrasound equipment. The exact clinical usefulness and the role of this new procedure awaits further clinical studies with surgical and pathological correlation.
