Introduction: Nineteen cases of posterior interosseous artery (PIOA) flap were reviewed. The patients' mean age was 24 (range 14-53) years.
Materials and methods: Nine patients were operated on as emergencies, and 10 patients were treated electively. Mean time of delay after trauma was 7.8 h (range 2-20 h) in emergency cases. Nine of them were non-replantable amputations. Skin defects were between 1.9 x 2.4 cm and 5.0 x 12.0 cm. Mean hospitalization time was 2.2 (range 1-5) days.
Results: Mean flap sensation was evaluated as 2.83-6.65 with the Semmes-Weinstein evaluation scale (only 2 patients scored less than 3.61). Five patients presented with discoloration and coolness. Average subjective evaluation was 8.2/10. Mean web opening after first web reconstruction was 40 degrees. One posterior interosseous neuropraxia ( recovered in 4 months), one distal flap necrosis, and one flap lost (due to infection) occurred as early complications. Mean follow-up was 12.8 months (range 15 days to 30 months).
Conclusions: PIOA flap applications have reduced the need for lateral arm and radial forearm flaps and also shortened hospitalization time in clinical practice.
