Simultaneous repair of the infected wound and digital nerve defect in the finger using a bipedicled nerve flap including nerve graft from the dorsal branch of the digital nerve.

Based on the Teoh et al.'s technique, we combined the nerve graft into the bipedicled heterodigital arterialized island flap and used this composite flap tissue for reconstructing complicated infected wound in the finger.

The 2-point Discrimination Test determines the minimal distance at which a subject can sense the presence of two needles. The modified American Society for Surgery of the Hand guidelines were used to stratify Discriminator 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 pulp. 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 4 mm as a limit of 2PD and considered this normal. The assessments were performed at a single time point at the final follow up.

The test points were at the center of the radial or ulnar portion of the pulp. The donor site, i.e. radial- or ulnar-dorsal aspect of the middle phalanx of the donor digit, was also evaluated.

Pain was given subjectively by the patient using the visual analogue scale (VAS). The VAS consists of a 10 cm line that was grouped into mild (1-3 cm), moderate (4-6 cm) and severe (7-10 cm).
