No part of this book may be reproduced in any form, by print, photoprint, microfilm or any other means without written permission from the author. Front and back pages: Three-dimensional reconstructions (ISG software on Allegro) of the magnetic resonance images (Philips, Gyroscan) of the foot of a patient with the hallux valgus complex. It shows the deviation of the flexor hallucis longus tendon (gray) in relation to the skeleton (yellow). The skin (purple) at the level of the first tarso-metatarsal and metatarso-phalangeal joint is also reconstructed in order to indicate the spatial orientation of the foot.
