Abstract
Abstract Introduction A complex wound is a wound that will not heal spontaneously or with simple or standard closure techniques. Often functional structures (bone, tendon, fascia, joint capsule etc.) are exposed and a matrix can be used for bridging of these structures. The Temporizing Matrix is an entirely synthetic matrix made from polyurethane open-cell foam. This matrix was used in the burn center for three years for the indication “complex wound” with good success. The study objective was to evaluate success rate (leading to wound closure after STSG, duration of treatment) and complications (infection, failure, scarring) on this patient cohort. IRB approval was obtained. Methods All charts of patients receiving the Matrix between June 2017 through May 2020 were reviewed. Data collected were demographics, surgery dates, wound descriptions, healing, infection, failure, reapplication, time from application to STSG, time to healing, post discharge complications and scar quality. Results 33 patients with 37 complex wounds were identified to meet inclusion criteria, 61% male, 39% female, age ranging from 3 months to 72 years. The wounds were caused by Burns, necrotizing infections, trauma or amputation post burn. The Matrix was placed for widely exposed structures (70%), failed STSG(3%), thin subcutaneous tissue coverage over amputation stumps (15%) and other reasons (12%). Primary graft success was 97%. Infection rate was 15% with 8% reapplication. Most infections were treated locally. The average Vancouver scar scale rating after discharge was 9/15. Conclusions This temporizing Matrix in preparation to STSG led to successful wound closure in 97% of these complex wounds with low complication rates and an acceptable long-term scar.
