NCT01533337 | Completed DMC

Brief 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.

Conditions

Nerve Injury; Digital Pulp Defect

Keywords

dorsal digital free flap; dorsal branch of proper digital nerve; dorsal branch of proper digital artery; proper digital artery

Outcome Measures

Primary Outcomes (1)

• 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.

OTHER

Free dorsal digital flap transferring is used for reconstruction of soft-tissue defects

Procedure: Free dorsal digital flap

Interventions

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.

Eligibility Criteria

• Age: 15 Years - 60 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Child (0-17), Adult (18-64)

You may qualify if:

• 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.

You may not qualify if:

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