Cross Transposition of Short Amputation Stumps for Reconstruction of the Thumb

Cross transposition of digital rays is illustrated by a case of amputation of the thumb and the middle finger. A remnant of the stump of the middle finger was mobilised and brought on top of the first metacarpal, in order to restore a functional length to the amputated thumb. A cross transposition of the second digital ray to the third was also carried out, closing the gap left by the resection of the third metacarpal.
