We investigated the maximal advancement of the homodigital neurovascular island flap with the digit in full extension and its correlation to the digital length. In 32 adult cadaveric digits, flaps measuring 1 × 1 cm were sequentially elevated to different dissection points. Dissection of the flap to the proximal interphalangeal joint crease, palmo-digital crease, division of adjacent digital artery and the superficial arch resulted in flap advancement of 8, 12, 15 and 18 mm, respectively. The degree of advancement correlated to the length of the finger and was approximately 19% of the finger length. We conclude that dissection of a homodigital antegrade neurovascular island flap to the proximal interphalangeal joint, palmo-digital crease, after ligation of adjacent digital artery and the superficial arch allows progressively more advancement. The advancement obtained by flap dissection to the palmo-digital crease was about 19% of the finger length.

Purpose:This study aimed to describe the reverse digital artery cross-finger flap (RDAC flap) in the treatment of failed finger replantation.Methods:This study retrospectively reviewed the records of patients who underwent modified RDAC flap reconstructions for failed finger replantation and assessed their outcomes. Of the patients who underwent soft tissue reconstructions for finger injuries between March 2011 and February 2015, we enrolled 11 patients in whom RDAC flap reconstruction procedures were performed to treat the failed replantations.Results:The flaps survived in all cases, with a mean static, two-point discrimination value of 5.3 mm (range, 4–7 mm) in the healed flaps. The sizes of the flaps ranged from 2 × 1 cm2to 2.3 × 1.5 cm2.Conclusion:The RDAC flap was introduced by Lai et al., and it is a mixed form with the advantages of both cross-finger flap and heterodigital island flap. Our results suggest that it could provide reliable coverage of the sensate soft tissue of fingers with failed replantation.

Monofilament Test

This fingertip reconstruction study retrospectively compared sensory recovery and active range of motion outcomes in neurovascular island advancement and reverse digital artery island flaps. Seventeen oblique triangular flaps and 14 reverse digital artery island flaps were performed for nail bed level fingertip amputations (Ishikawa subzone II). There was no significant difference between the two procedures in the Semmes–Weinstein monofilament test and range of motion results. For static and moving two-point discrimination tests, however, those with a reverse digital artery island flap required a longer period for sensory recovery compared to those with an oblique triangular advancement flap. This trend equilibrated at 12 months after surgery showing no significant difference in both static and moving two-point discrimination tests between the procedures.

Aesthetic Results

The fingertip has an important role in bi-digital pinch quality, and pulp loss is common and difficult to solve. The pulp switch consists of a pulp island flap with a homodigital neurovascular pedicle, vascularized by the palmar digital artery of the non-dominant pulp transposed to the dominant pulp side. We report the results in 16 patients treated for loss of the dominant half of a digital pulp from January 2000 to December 2008. On review after a minimum of 6 (range 6–18) months, the Weber’s test demonstrated an average of 8 mm in static 2 point discrimination test for all digits, except the ring finger. In the monofilament Semmes–Weinstein test, we obtained a score of 3.61 for the thumb and little fingers, and 4.31 for the other fingers. We did not find partial or total necrosis of the flap. The pulp switch flap gave satisfactory functional results for viability, sensitivity, and digital mobility providing a sensate bi-digital pinch with acceptable aesthetic results in a single surgical procedure.
