Reverse posterior interosseous flap in childhood: a reliable alternative for complex hand defects.

Restoration of complex hand defects in children is still problematic because of the limited choices of treatment. The reverse posterior interosseous flap is a versatile flap, with successful results shown in adults. The purpose of this study was to highlight the utility and versatility of the flap and to simplify the technique for ease of harvest in the pediatric age group. Complex hand defects were repaired using this flap in 10 children. Ages of the patients averaged 9.1 years. Fasciocutaneous and osteofasciocutaneous flaps were used in 7 and 3 children, respectively. All flaps survived completely. The average time of bone union was 3 months. This flap can be used with safety and versatility in coverage of children's upper limb. The diameter of the vessels is not a handicap in the flap dissection. Harvest of the flap is easy and rapid, and the operation time is short, as in adult patients.
