# Novel Techniques in Fractional Skin Replacement

## TL;DR

This review explores new methods for replacing skin in wound treatment that aim to improve outcomes and reduce complications.

## Contribution

The paper introduces and reviews novel fractional skin replacement techniques as alternatives to traditional grafts.

## Key findings

- Fractional skin replacement can improve outcomes for large wounds.
- Fractionated skin reduces donor site morbidity compared to traditional grafts.
- Both mechanical and chemical methods are used to fractionate skin.

## Abstract

The gold standards for coverage of wounds that cannot be primarily closed are full thickness skin grafts (FTSGs) and split thickness skins graft (STSGs). FTSGs harvest sites generally require primary closure, which limits availability, especially when treating larger wounds. STSGs have many shortcomings, including donor site morbidity. Fractional autologous skin replacement can be utilized in conjunction with or in lieu of STSGs to both improve graft outcomes of large wounds and to decrease donor site morbidity. Skin can be mechanically or chemically fractionated. Fractionated skin can be advantageous, as adnexal structures provide additional functionality without donor site morbidity. In this review, we will discuss current and emerging techniques in fractional skin replacement.
