[APPLICATION OF THE DOUBLE SKIN PADDLE ARTERIALIZED VENOUS FLAPS FOR RECONSTRUCTING SOFT TISSUE DEFECTS OF MIDDLE AND PROXIMAL PARTS OF DOUBLE FIGURES].

Objective: To investigate the application of the double skin paddle arterialized venous flaps for reconstruction of soft tissue defects in the middle and proximal parts of double fingers.

Methods: Between September 2011 and December 2014, 6 cases (12 fingers) of soft tissue defects in the middle and proximal parts of double fingers underwent reconstructive surgery with the double skin paddle arterialized venous flaps. There were 5 males and 1 female with an average age of 33.8 years (range, 19-52 years). The causes included cut injury in 4 cases and crush injury in 2 cases. Five index fingers, 3 middle fingers, 2 ring fingers, and 2 little fingers were involved. All defects located at proximal and middle fingers and defect did not exceed the distal interphalangeal joint. The defect area ranged from 2.5 cm x 2.5 cm to 5.5 cmx4.0 cm. All cases had bone or tendon exposure, and 2 cases had phalangeal fracture. The disease duration was 1.5-7 hours (mean, 3.5 hours). The flap size was 8 cm x 3 cm-14 cm x 5 cm. The donor site was directly sutured (≤ 3.0 cm in width) or was repaired with skin graft (> 3.0 cm in width).

Results: The operation time was 2.5-5.0 hours (mean, 4.0 hours). All flaps survived completely. Tensive blisters occurred in 4 cases and were improved at 1 week after removal of suture around pedicle. Partial distal flap necrosis was noted in 1 case, healing was obtained after secondary debridement; other wounds healed in one stage. The patients were followed up 6-18 months (mean, 13 months). The flap had good texture, elasticity, and appearance. According to the hand function evaluation criteria issued by the Chinese Hand Society, the results were excellent in 3 cases, good in 2 cases, and fair in 1 case at last follow-up. The two-point discrimination of the flap was 8-10 mm (mean, 9 mm).

Conclusion: The double skin paddle arterialized venous flaps have the advantages of simple technique and definite effectiveness for reconstruction of soft tissue defects in the middle and proximal part of double fingers.
