Abstract
Aim: The goal of this study was to compare success rates of a regenerative limb salvage approach (rLS) using dehydrated human chorion amnion membrane (dHACM) to traditional flap-based limb salvage (fLS). Materials & methods: This prospective RTC enrolled patients presenting with complex extremity wounds over a 3-year period. Primary outcomes included success of primary reconstruction, persistence of exposed structures, time to definitive closure, and time to weight bearing. Results: Patients meeting inclusion criteria were randomized to fLS (n = 14) or rLS (n = 25). The primary reconstructive method was successful for 85.7% of fLS subjects and 80% of rLS subjects (p = 1.00). Conclusion: This trial provides strong evidence that rLS is an effective option in the setting of complex extremity wounds, with success rates comparable to traditional flaps. Clinical Trial Registration: NCT03521258 (ClinicalTrials.gov).

Abstract
A growing body of literature demonstrates the clinical promise of dehydrated human amnion/chorion membrane (dHACM), a cryopreserved tissue product derived from placental amniotic membrane, to enhance post-operative wound healing. The purpose of this study is to review the potential of dHACM to facilitate post-surgical and myelomeningocele wound repair. A comprehensive literature search of PubMed was conducted to identify studies investigating dHACM use in pediatric and surgical wound care published from inception to October 2020. For each study, patient characteristics, wound characteristics, and outcomes following dHACM application were documented and assessed. Of the 190 articles reviewed, 15 publications were included in the final analysis. Results demonstrated that the average wound healing time varied across clinical indications (e.g., 14 days for trauma reconstruction to 116 days for Moh's surgery repair). Across indications, pediatric patients had shorter healing periods compared to adults (P < 0.01). Chronic wounds (> four weeks old) were documented in both adult (n = 3) and pediatric (n = 2) wound repair publications; all chronic surgical wounds demonstrated complete wound closure with dHACM. No complications from dHACM use were reported. Advantages of dHACM included increased patient satisfaction, cost-savings, and faster wound healing. We then present two cases of myelomeningocele wound repair facilitated successfully by dHACM. Overall, dHACM proves to successfully expedite wound repair in pediatric patients with chronic or complicated wounds such as those from myelomeningocele repair. It is important for surgeons to consider wound duration, size, and patient age to better predict graft success in enhancing wound repair.

Abstract
Consistently achieving wound closure requires a broad understanding of wound physiology, anatomy and wound healing phases. The multifaceted principles of wound closure are comprised of: perfusion evaluation; diabetes control; nutritional optimisation; infection control; mechanical stress avoidance; oedema management; wound bed preparation; and community care. Optimisation of each element is crucial to timely and durable resolution of acute and hard-to-heal wounds. This objective is realisable only through an interdisciplinary approach to wound healing. The reconstructive ladder represents the graduation of complex wound management as applied by the specialty of plastic surgery. The approach to reconstruction typically begins with the least invasive option, which is considered reliable. However, there are instances when the most reliable option on the reconstructive ladder is not a viable option and creative solutions for wound closure are required. The following case report demonstrates a unique approach to lower extremity salvage in a subacute compound fracture surgical site infection using a limited reconstructive ladder.

Abstract
Lay SummaryRecently, the use of the human amniotic membrane (hAM) has been extended to treat retinal disorders such as refractory macular holes, retinal breaks and dry and wet age-related macular degeneration. Not only the hAM has proved to be an excellent tool for repairing retinal tissue, but it has also shown a promising regeneration potential. This review aims to highlight the novel use of the hAM in treating retinal diseases. Although the hAM has been used in the ocular anterior segment reconstruction for more than 60 years, in the last 2 years, we have found in literature articles showing the use of the hAM in the retinal surgery field with interesting results in terms of tissue healing and photoreceptor regeneration.

Abstract
Background: Skin substitutes are designed to accelerate wound healing by providing replacement of extracellular matrix and can be used to promote healing of both acute and chronic wounds.Aim: To describe advantages, disadvantages, and indications for different skin substitutes with the intention of providing a systematic framework that clinicians can easily utilize in clinical practice.Materials and method: We conducted a PubMed, Cochrane Library, and company website search for publications using various search terms associated with skin substitutes.Results: Skin substitutes can be categorized as epidermal, dermal, and composite, depending on the skin component they contain, and further split into different categories depending on their composition and source of material, including xenograft, acellular allograft, cellular allograft, autograft, and synthetic skin substitutes. Because there is no ideal option for skin substitutes that meet all the criteria for optimal wound healing, there is ongoing research evaluating and developing different skin substitute options.Conclusion: Our model of skin substitutes was organized based on the different layers of cutaneous involvement and the origin of the product material. We believe that this framework provides a practical guide for selection of the most appropriate skin substitute based on clinical indication.

Abstract
OBJECTIVE Over two million individuals worldwide, with end-stage renal disease (ESRD), depend on dialysis therapy or a kidney transplant for survival. Every haemodialysis patient requires vascular access. The arteriovenous fistula (AVF) is preferred for long-term hemodialysis vascular access due to long-term primary patency rates. Given the limited options for haemodialysis access and placement, preservation of existing AVF sites is always a clinical priority. This case report describes a novel approach to wound closure with the application of dehydrated amnion chorion human membrane (dHACM) at an AVF surgical site known to be complicated with issues of scarring and tissue breakdown. The patient was treated successfully with the imperative preservation of his AVF given that he had few other vascular access options.
