Distal leg and foot have unique anatomical characteristics, and multiple etiologies may cause defects in various patterns that mandate reconstruction. Local flaps, such as perforator flaps, can give good outcomes with less complication. The lateral supra malleolar flap can effectively cover the distal leg and foot defect. In this article, we highlight the utility of this flap and its outcome.
This study is a descriptive, retrospective, multi-center, hospital-based performed to assess the efficacy of lateral supra malleolar flap in the reconstruction of distal leg and foot defects in Sudan during 2023-2024. The study included all patients presenting with various types of defects in the distal leg, ankle joint, and foot who were treated with the lateral supra malleolar flap.
The study included thirty-one patients, with 26 males (83.9 %) and 5 females (16.1 %). The largest age group was 30 to 40 years, with 12 patients (38.7 %). Weapon injuries were the most frequent, affecting 21 patients (67.7 %), followed by 6 patients (19.4 %) from road traffic accidents. Of the patients, 12 (38.7 %) had defects due to bone fractures, and 9 (29 %) had tendon injuries. Infections were reported in 4 (12.9 %), and 6 (19.4 %) patients experienced partial flap necrosis as a complication.
The lateral supra malleolar flap is a powerful choice for lower limb reconstruction. It provides tissue that closely resembles the texture and color of the leg and foot. This flap avoids damaging main blood vessels and can easily reach the foot. It is straightforward to use and has fewer complications than other techniques.
小腿远端和足部具有独特的解剖学特征，多种病因可导致不同类型的缺损，需要进行重建。局部皮瓣，如穿支皮瓣，可取得良好效果且并发症较少。外踝上外侧皮瓣可有效覆盖小腿远端和足部缺损。在本文中，我们重点介绍了该皮瓣的实用性及其效果。
本研究是一项描述性、回顾性、多中心、基于医院的研究，旨在评估2023 - 2024年期间外踝上外侧皮瓣在苏丹重建小腿远端和足部缺损中的疗效。该研究纳入了所有因小腿远端、踝关节和足部各种类型缺损而接受外踝上外侧皮瓣治疗的患者。
该研究纳入了31例患者，其中男性26例（83.9%），女性5例（16.1%）。最大年龄组为30至40岁，有12例患者（38.7%）。武器伤最为常见，影响21例患者（67.7%），其次是道路交通事故患者6例（19.4%）。在这些患者中，12例（38.7%）因骨折出现缺损，9例（29%）有肌腱损伤。报告有4例（12.9%）发生感染，6例（19.4%）患者出现部分皮瓣坏死作为并发症。
外踝上外侧皮瓣是下肢重建的有力选择。它提供的组织在质地和颜色上与小腿和足部非常相似。该皮瓣避免了损伤主要血管，且能轻松到达足部。其使用简便，并发症比其他技术少。
