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.

| Type | Measure | Description | Time frame | Safety issue |
|---|---|---|---|---|
| Other | Tinel's Sign | Tinel's sign was graded as the following: grade 1=none; grade 2=mild, slight tingle; grade 3=moderate, very uncomfortable; and grade 4=severe, patient unable to use hand because of any stimulation of the neuroma | 20-26 months postoperatively | |
| Primary | Static 2-point Discrimination Test | The Static 2-point Discrimination Test determined the minimal distance at which a subject can sense the presence of two needles. The modified American Society for Surgery of the Hand guidelines was used to stratify the 2PD measurements (excellent <6 mm; good 6-10 mm; fair 11-15 mm; poor >15 mm). The test points were at the center of the radial or ulnar portion of the finger pulp (i.e., injury side). Each area was tested 3 times with a discriminator (Ali Med, Dedham, MA). Two out of 3 correct answers were considered proof of perception before proceeding to another lower value. We stopped at 4mm as a limit of 2PD and consider this normal. The measurements were performed at a single time point at the final follow up. | 20-26 months postoperatively | |
| Secondary | Cold Intolerance Severity Score (CISS) Questionnaire | The maximum score was 100 and was grouped into 4 ranges (0-25; 26-50; 51-75; and 76-100), corresponding to mild, moderate, severe, and extreme severity, respectively. | 20-26 months postoperatively |
