What is hard and soft neuroma?

Asked by Kalesh 

If the neuroma feels soft, or if there is conduction across the lesion, resection is not advised. If the neuroma is hard and there is no conduction on nerve stimulation, it should be resected, paring back the stumps until healthy fascicles are exposed.

Microscopically, neuroma can be of hard and soft variety, according to the amount of fibrous tissue.

The neuroma should be palpated to see if it is hard and fibrous; a large hard neuroma indicates poor regeneration.
