Painful neuromas: a review of treatment modalities.

There are numerous methods cited in the literature on the treatment of painful neuroma. Nonsurgical methods range from injections with various materials into the nerve end to desensitization of nerve pain conduction pathways. Some surgical treatments aim to alter the environment of the amputated nerve end by transposing it into muscle or bone, others have designed various flaps to protect truncated nerve ends from scar tissue, and still others try to "cap" the nerve with silicon, a nerve graft, or epineurium to prevent nerve regeneration. All of these methods have proved efficient. However, none of these methods work universally. The authors review the common treatments for painful neuromas. In addition, they review the preliminary results of the extended autologous venous nerve conduit as a novel technique of treating painful neuromas. They also report recent investigations into the pathophysiology of injured nerves.
