Use of the Free Dorsal Digital Flap Including Both Dorsal Branches of the Proper Digital Nerves 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.
|Study Design:||Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
- static 2-point discrimination (2PD) test [ Time Frame: 25 months ] [ Designated as safety issue: No ]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.

Procedure: Free dorsal digital flap
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.
