Objective:
To investigate the therapeutic effect of reverse radial hypothenar flap for finger soft tissue defect.
Methods:
From Mar. 2006 to Mar. 2010, 13 cases (14 fingers) with finger soft tissue defects were treated with reverse radial hypothenar flaps pedicled with ulnar palmar digital artery of little finger. The defects were 1.9 cm x 1.5 cm -4.0 cm x 2.0 cm in size. The flap size ranged from 1.5 cm x 2.0 cm to 4.0 cm x 2.0 cm.
Results:
All the flaps survived completely with primary healing both in donor and recipient area. 12 cases (13 fingers) were followed up for 1-3 years. The flaps color was similar to the unaffected fingers. Cicatricial contracture happened in one case due to contracture of palmar fascia. The two-point discrimination distance on flap was 3.2-5.3mm. The active and passive movement of finger joints was evaluated as excellent in 12 fingers, good in one finger. There was no complaint about the feeling at the donor site. Two months after operation, all patients could go back to work.
Conclusions:
The reverse radial hypothenar flap is very suitable for finger soft tissue defect with less morbidity to donor site.
