Objective: To introduce the application of reverse dorsal radial flap in reconstruction of distal segment defect of thumb.
Methods: From January 2004 to June 2007, 24 cases of soft tissue defect with exposed bone or tendon at the distal segment of thumb were involved. The flap size ranged from 2 cm x 2 cm to 3 cm x 4 cm.
Results: Venous congestion happened in 3 cases with one case of partial necrosis at the distal end of the flap. All the other flaps survived completely. The follow-up period was 6 - 24 months. The appearance and function of the thumbs were satisfactory. The 2-point discrimination was 7 - 11 mm (mean 9.3 mm).
Conclusions: Reverse dorsal radial flap is a good option for reconstruction of distal segment defect of thumb.
