We suggest that symptomatic traumatic neuromas - benign lesions of incompletely understood etiology develop when neural fiber regeneration occurs in the presence of excessive fibrous tissue proliferation. Subsequent contraction of wound and scar myofibroblasts leads to compression of the regenerating nerve fibers and further stimulation of the overgrowth of their perineurial cells as a protective response. This chronic process leads to a stow enlargement of the proliferating mass and the typical histological picture of a traumatic neuroma, in which multiple interlacing fascicles of nerve fibers are encased in condensed fibrous tissue. To avoid the development of a traumatic neuroma, we propose that an injured or a transected nerve should be placed out of the site of potential excessive fibroproduction and/or that all external factors leading to excessive fibroproduction development be eliminated from the wound site.
