An exquisitely neuralgic stump is usually made so by the entanglement of nerve ends and their subsequent enlargement into so-called amputation stump neuromas (which are histologically fibromas), from pressure upon nerve terminals. Under these circumstances their excision through incisions planned for the purpose, or the exsection of a portion of the nerve trunk at a higher level, may be necessitated ([Fig. 717]).
