Background:
Reconstruction of soft tissue defects in the hand need an early, single stage and well vascularised cover to achieve the best functional result. Usually a full thickness graft is required since vital structures like tendons, bones and joints are exposed and often there is need for secondary reconstruction.
Methods:
We managed 12 cases of complex defects over the hand in the last 2 years with the posterior interosseous artery flap.
Results:
In 5 cases the defect was due to blast injury and in 4 because of crush injury. Males predominated in the ratio of 5:1. The defect was most often in the 1(st) web space and the largest flap was 11×8 cm. In all but one case the donor site was covered by split skin graft, which settled well. 2 patients had superficial flap necrosis needing debridement and skin graft.
Conclusion:
Flap based on reverse flow in the posterior interosseous artery is a versatile and reliable source for full thickness cover of complex soft tissue defects in the hand.
