Purpose: High tension electrical injuries result in major tissue(eg. bones, tendons, vessels and nerves) destruction. Therefore, the management of mutilating wrist caused by electrical injuries still represents a challenge. There are various approaches to this problem including local and regional flaps as well as pedicled distant flaps and microsurgical free tissue transfer. Although it has not gained wide acceptance, because of the technically demanding dissection of the pedicle, posterior interosseous flap is now well accepted for the reconstruction of hand and wrist in hand surgery. The principal advantages of this flap are minimal donor site morbidity, minimal vascular compromise, one stage operation. This flap also offers the advantages of ideal color match and composition. In this report, we describe our experience with the reverse posterior interosseous island flap for reconstruction of mutilating wrist with main vessel injuries.
Methods: From October, 2004 to June, 2006, we treated 11 patients with soft tissue defects and main vessel injuries on the wrist that were covered with reverse posterior interosseous island flap.
Results: These 11 patients were all male. The ages ranged from 27 to 67 years(mean age 41.75) and the follow-up period varied from 4 to 19 months. Complete healing of the reverse posterior interosseous island flaps were observed in 11 patients(12 flaps). The majority of these flaps showed a certain degree of venous congestion, which in a flap was treated with medical leech. 1 flap has partial necrosis owing to sustained venous congestion, requiring secondary skin graft. flap size varied from 3.5x8cm to 10x12cm(mean size 6.4x8.9m). The donor site defect was closed directly in 5 flaps, and by skin graft in 7 flaps.
Conclusion: We found that the reverse posterior interosseous island flap is reliable and very useful for reconstruction of mutilating wrist and we recommend it as first choice in coverage of soft tissue defects in the wrist with electrical arc injuries.
