The neuroma-like structure of the long-time severed and isolated nerve stumps

[摘要] The long-time severed and isolated intermediate and distal nerve segments, maintained undisturbed in their connective tissue bed, completely separated from each other and from the proximal stump, are repopulated by nerve-fibres which origin is still unknown. The extremities of such nerve segments present complex nervous nodules capped by fibrous tissue, neuroma-like structures.
