Proximal upper limb amputation not only leads to serious local disability but carries with it substantial systemic implications. The replantation of an avulsed limb is all too frequently followed by disappointing functional results. In children, however, with secure bony stability, vascular reconstruction and immediate appropriate nerve repair the results of replantation can be most gratifying. Two such cases have been seen at The Hospital for Sick Children and are reported in detail. The late functional results as illustrated make this complex procedure a very worthwhile undertaking.
