Case presentation
The patient was a male truck driver in his fifties, who had his left
annular finger amputated in an accident 2 years previously. Owing to
poor pain control at the stump of his finger, he was referred to our
department. The initial examination revealed pain in the left annular
finger transection as well as allodynia. Although some pain relief had
been observed with postoperative medication, he still had persistent
resting pain of about Numerical
Rating Scale (NRS) 4/10. Therefore, blocks of the ulnar nerve and median
nerve were performed. After the blocks were performed, the pain improved
to NRS 1 to 2/10, and pain upon movement also almost disappeared.
