AbstractThe purpose of this study was to examine the differences between the use of a posterior interosseous artery (PIA) flap and an anterolateral thigh (ALT) flap for post-traumatic, medium-sized soft tissue reconstruction of the hand based on flap characteristics, postoperative complications, and aesthetic outcomes.From October, 2010 to March, 2016, 62 patients undergoing soft tissue reconstruction of the hand with 30 PIA flaps and 32 ALT flaps were included in this study. The 62 patients were divided into the PIA flap group and the ALT flap group. The differences between the 2 groups were analyzed.The 62 patients included 52 males and 10 females, and the mean age at the time of surgery was 41 years. The flap failure rate was 13.3% (4/30) in the PIA flap group and 9.4% (3/32) in the ALT flap group. No significant differences in flap failure rate, recipient site complication rate, or donor site complication rate were observed between the 2 groups. However, the operative time (136 min vs 229 min) and aesthetic outcomes (flap bulk swelling, 0 cases vs 31 cases) were statistically significantly different.Both the pedicled PIA flap and the free ALT flap were comparable for the reconstruction of post-traumatic, medium-sized soft tissue defects of the hand according to the evaluated outcomes of postoperative complications. Based on the surgical characteristics of the flap and the evaluation of aesthetic outcomes, the pedicled PIA flap was significantly superior to the free ALT flap.Copyright © 2021 the Author(s).
