Tripaddle Posterior Interosseous Artery Flap Design for 3-Finger Defects: An Evaluation of 3 Surgical Approaches.

Introduction: The tripaddle posterior interosseous artery (PIA) flap can be used for multifinger defect resurfacing, but interpatient variations in perforator distribution remain an ongoing challenge when using this approach. This study aims to evaluate the efficacy of 3 different tripaddle PIA perforator flap designs according to the PIA perforator distribution for the repair of 3-finger defects.

Methods: In accordance with the size of the 3-finger defects and the position of the perforators, a tripaddle flap was designed on the multiple perforators of the descending branch of the PIA in the distal two thirds of the forearm.

Free multilobed posterior interosseous artery perforator flap for multi-finger skin defect reconstruction.

Background: The posterior interosseous artery (PIA) perforator flap can be used for reconstruction of soft-tissue defects of fingers. Based on the multiple perforators from the posterior interosseous artery, we describe a technique to reconstruct the multi-finger defect in the use of the free multilobed PIA perforator flap.

Methods: PIA perforators from different areas of the forearm were used to design a free multilobed skin paddle for multi-finger skin defect reconstruction.
