Abstract: | The need for soft tissue coverage of large defects in the hand and the wrist following trauma is a common problem for hand
surgeons. Flap coverage of these defects can be either in the form of distant or regional flaps. The posterior interosseous
artery flap recently has emerged as a front runner in these situations by its virtue to preserve both the major arteries to
the hand. Thirty-two posterior interosseous artery flaps were used in 32 patients with complex soft tissue defects of the
hand. All these defects were posttraumatic. There were associated skeletal and soft tissue injuries in 20 patients. The donor
site was closed either primarily or by a split skin graft depending on the size of the defect. All flaps healed well, and
there were no incidences of flap necrosis. The donor site required a split skin graft in 24 patients. The flap was bulky in
one patient and transient extensor carpi ulnaris weakness was seen in three patients. The posterior interosseous artery flap
is a versatile flap for coverage of soft tissue defects of the hand. Good aesthetic results can be achieved with minimal donor
site morbidity. Harvesting the flap requires a precise surgical technique and as many perforators as possible should be preserved
to ensure flap viability. |
