Pilot Study of Additive Effect of “Offloading Ilizarov Frame” To Reduce “Reverse Sural Flap” Surgery Complications: A Clinical Trial

Abstract

Background: A reverse sural flap is an available surgical technique because it provides robust axial blood circulation to flaps with a substantially larger surface area. We aimed to assess Ilizarov frames outcome after reverse sural flaps among patients with traumatic injuries to the distal portion of the leg. Methods: Patients with traumatic distal injury of leg in Shoha-e Tajrish Hospital in 2022-2021 were recruited and treated with reverse sural flaps. Interventional group was followed by Ilizarov frames application (group A). For the second group, just conventional dressings and proper positioning were done after surgery (group B). Between the two groups, the duration of surgery, the degree of flap swelling, the time from surgery to discharge and flap failure, surgical site infection, deep vein thrombosis (DVT), and other complications were compared using SPSS 25 software. Results: Of 26 recruited patients, twenty consented to participate in this study. The average time from initial injury to reconstruction surgery, the mean duration of surgery, the mean time from surgery to discharge and the degree of swelling of the flap was compared between these two groups. The results showed better outcome in Ilizarov group, but the flap swelling grade was the only statistically significant factor between groups ( P value= 0.03). Conclusions: The use of “offloading Ilizarov frames” to protect reverse sural flaps resulted in a considerable reduction in the flap swelling. It is a safe, quick, easy, and effective technique.
