[Thumb reconstruction by means of transposition of a damaged little finger and interposition splint after an explosion injury to the hand].

This case report concerns the loss of the thumb, the middle and ring fingers as well as the distal phalanx of the little finger as a result of an explosion. A combined procedure for the reconstruction of a thumb was performed employing interposition lengthening of the first metacarpal by an iliac crest bone graft followed by the transposition of the distal part of the remainder of the little finger. The proximal portion of that digit was preserved in order to obtain better span grasp.
