Free Dorsal Digital Flap for Reconstruction of Volar Soft Tissue Defect of Digits

The aim of the current report is to investigate the feasibility of transferring the free dorsal digital flap, including both dorsal branches of the proper digital nerves (PDNs), to reconstruct the volar soft tissue defect of digits. Sensory restoration of the reconstructed digit was evaluated via static two-point discrimination (2PD). The range of motion (ROM) of the donor middle and ring fingers was measured.

About this study

Sensory restoration of the reconstructed digit was evaluated via static two-point discrimination (2PD). The range of motion (ROM) of the donor middle and ring fingers was measured. The data were compared with those of the contralateral, uninjured hand.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

soft tissue defects in the fingertip, pulp, or volar surface of the digits;
a defect > 2 cm in length;
unavailability of the homodigital and heterodigital island flaps because of concomitant injuries to donor fingers; and
the patient refuses to use tissues from the toe.

Exclusion criteria

soft tissue defects in the dorsum of the digits;
a defect < 2 cm in length;
homodigital and heterodigital island flaps are available.

Treatment and study plan

Free dorsal digital flap

Procedure

The dorsal digital flap, including both dorsal branches of the proper digital nerves, was designed on the dorsum of the donor finger between the distal third of the proximal phalanx and the distal interphalangeal joint.

Primary outcomes

static 2-point discrimination (2PD) test

Time frame: 25 months

The test points were at the centers of the radial and ulnar portions of the digital pulp and the donor sites separately. Each area was tested 3 times with a Dellon-Mackinnon discriminator. Two out of 3 correct answers were considered proof of perception before proceeding to another lower value.
