Treatment of Hand Allodynia Resulting from Wrist Cutting with Radial and Ulnar Artery Perforator Adipofascial Flaps.

In this article, we report two cases in which recurrent adhesive hand neuropathy with allodynia were successfully treated with radial and ulnar artery adipofascial perforator flap coverage. Treatment of recurrent neuropathy, such as recurrent carpal tunnel syndrome and re-adhesion after neurolysis using free and pedicle flaps to cover the nerves, has been reported to show good results. However, for severe painful nerve disorders, such as complex regional pain syndrome, the efficacy of this treatment was unclear. We present two cases diagnosed with recurrent adhesive hand neuropathy with allodynia, resulting from wrist cutting; these cases were treated with neurolysis and flap coverage with good results and no recurrence. This suggests that neurolysis and flap coverage are effective methods for treating complex regional pain syndrome.
