Abstract
Once developed, traumatic neuromas cause persistent and intense pain and disrupt daily life. When the distal end of the nerve is available for surgical management of neuromas, nerve reconstruction is performed after excision. We herein report a case in which bridging of the nerve using a collagen nerve conduit filled with collagen filaments was employed for neuroma-in-continuity involvement in the finger. This intervention resulted in pain reduction. Bridging nerve defects after neuroma excision using a collagen nerve conduit facilitates axonal regeneration and prevents axon infiltration into the surrounding skin. Utilizing a collagen nerve conduit for nerve reconstruction is a crucial option in the surgical treatment of neuromas and has the potential to prevent neuroma recurrence.
(a) A neuroma-in-continuity was identified in the digital nerve on the palm side. The figure shows the neuroma after being cut in the middle. (b) After the neuroma was excised, the nerve was bridged using Renerve® .
