Hypertrophic scar formation and non-healing wounds following Achilles tendon repair arise from poor vascularity to the incisional site or from excess mechanical stress/strain to the incision during the healing process. The embrace® scar therapy dressing is a tension offloading device for incisional scars. This study explored the effects of tension offloading during Achilles scar formation. A healthy 30-year-old male without any medical co-morbidities developed an acute rupture of his left Achilles tendon. The patient underwent open repair 1 week after injury. At post-operative day (POD) 14, the patient started daily tension offloading treatment on the inferior portion of the incision through POD 120. By POD 120, the untreated portion of the Achilles incision appeared hypertrophic and hyperpigmented, while the treated portion of the scar appeared flat with minimal pigmentation changes. The 12-week treatment of tension offloading on an Achilles tendon repair incision significantly improved cosmesis compared to untreated incision.
跟腱修复后肥厚性瘢痕形成和伤口不愈合，是由于切口部位血运不佳或愈合过程中切口受到过度机械应力/应变所致。embrace®瘢痕治疗敷料是一种用于减轻切口瘢痕张力的装置。本研究探讨了跟腱瘢痕形成过程中减轻张力的效果。一名30岁健康男性，无任何内科合并症，发生左跟腱急性断裂。患者受伤1周后接受了开放性修复。术后第14天，患者开始在切口下部进行每日张力减轻治疗，持续至术后第120天。至术后第120天，跟腱切口未治疗部分出现肥厚和色素沉着，而瘢痕治疗部分则显得平坦，色素沉着变化最小。与未治疗的切口相比，对跟腱修复切口进行12周的张力减轻治疗显著改善了美观。
