Clinical Trial Summary

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.

Description:

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.

Intervention

Procedure:
• Free dorsal digital flap
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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	static 2-point discrimination (2PD) test	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.	25 months
