The ulnar digital artery perforator flap for little finger defects: Using the abductor digiti minimi as a landmark – Surgical technique

Abstract

This surgical technique article outlines the planning and harvesting methods for the ulnar digital artery perforator (UDAP) flap, using the abductor digiti minimi as a landmark for flap elevation. This approach demonstrates a reliable perforator and offers a wide range of coverage for little finger reconstruction, both on the palmar and dorsal sides. The UDAP flap is technically straightforward and easily accessible and results in minimal donor site morbidity, making it a highly viable option for little finger defects. The technique’s simplicity and effectiveness represent a significant advancement in reconstructive surgery for the little finger.
