Migration of the fixation device to a part of the body is well known complication of fracture treatment. However, few reports of this complication have appeared in the literature. The present report concerns two instances of the migration of a K-wire and a Steinmann pin from the acromioclavicular joint, respectively, into the neck. It appears that if wires and pins are used for fixation, the lateral ends should be bent to prevent medial migration, and as soon as the desired therapeutic results have been obtained, these must be subsequently removed.
