# Considerations in Flap Selection for Soft Tissue Coverage of the Hand and Digits

## TL;DR

This study evaluates different flap techniques for hand and finger reconstruction, showing their effectiveness in achieving good functional and aesthetic results.

## Contribution

The study provides a real-world assessment of perforator and local flaps for hand reconstruction in a high-complexity patient population.

## Key findings

- Satisfactory soft tissue coverage was achieved in 35 out of 37 patients.
- Functional outcomes were favorable with restored joint mobility and no secondary deformities.
- Complications were rare, with only two cases of flap failure or partial necrosis.

## Abstract

Background/Objectives: The goal of reconstructive hand surgery is to achieve both functional and aesthetic restoration. The primary aim of this study is to perform a detailed, practice-oriented evaluation of perforator-based and local flaps for soft-tissue reconstruction of the hand and digits, focusing specifically on their functional reliability, anatomical consistency, complication profile, and aesthetic integration in a real-world, high-complexity referral population. Methods: This retrospective single-center study included 37 patients with soft tissue defects of the hand that required flap coverage between September 2021 and September 2024. The study assessed patient demographics, defect characteristics, flap selection, surgical techniques, and outcomes including satisfactory soft tissue coverage, functional results and occurrence of complications. Various perforator flaps were analyzed, including the dorsal metacarpal artery flap, reverse radial forearm flap, reverse posterior interosseous artery flap, reverse homodigital and heterodigital island flaps, and the thenar flap. Results: Satisfactory soft tissue coverage was achieved in 35 out of 37 patients. One case involved partial distal flap necrosis, and another presented with Foucher flap failure. The remaining flaps demonstrated stable integration, preserved perfusion, and durable soft-tissue coverage with satisfactory contour and pliability. Functional outcomes were favorable, with restoration of joint mobility and absence of secondary deformities. Conclusions: This study supports the continued use of perforator and local flaps in upper extremity reconstruction, emphasizing the need for individualized planning to optimize the outcomes.
