About

Neuroma excision and digital nerve reconstruction remain the best option for the treatment of Painful Digital Neuroma (PDN). When the distal nerve end is preserved, conventional nonvascularized nerve grafting is the primary option to bridge the defect. The investigators hypothesize the pedicled nerve flap taken from the dorsal branch of the homolateral digital nerve is better than conventional methods for reconstruction of the digital nerve defect after painful neuroma resection.

This study reports treatment of painful digital neuroma using a pedicled nerve flap taken from the dorsal branch of homolateral digital nerve. From May 2007 to March 2010, the patients had previous nerve injuries with or without nerve repair. The mechanisms of injury include sharp cut, avulsion and crush. The defects were between the middle of the distal phalanx and the palmar digital crease.

Full description

Our selection criteria in this study included a patient with PDN in a scarred wound bed or poor coverage, a PDN located between the middle of the distal phalanx and the palmar digital crease, and a defect of the digital nerve after neuroma resection equal to or less than 3 cm in length. The exclusion criteria included a PDN in healthy soft tissue, a digital nerve defect longer than 3 cm, injury to the course of the pedicle or the donor nerve, and a thumb neuroma. A finger with a small distal end of the digital nerve was also excluded, because neurorrhaphy was extremely difficult in this situation.
