Among lower extremity chronic wounds, heel ulcers present one of the greatest challenges to the wound care provider. The potential for these ulcers to progress to osteomyelitis of the calcaneus is well known. The concept of "what to take off the wound" is a known clinical axiom; however, extensive debridement or surgical reconstruction including a partial calcanectomy can significantly impair the patient's ambulation, balance, and overall functional mobility. Critical to the wound healing process is the need to replace damaged cells. The use of cellular therapy to achieve wound closure has added to the armamentarium of the wound care specialist. Among several commercially available advanced wound products, the Food and Drug Administration has approved only 1 living bilayered cell therapy (Apligraf) for use with standard therapy in the treatment of venous ulcers, as well as for full-thickness neuropathic diabetic foot ulcers. Apligraf has the capability to express multiple growth factors found in normal skin, thus potentially providing a biologically active matrix in the wound. This case review summarizes the use of living bilayered cell therapy in 10 heel ulcerations. The use of Apligraf with appropriate pressure offloading resulted in effective wound closure, leading to an alternative care plan for patients with heel ulcers.
在下肢慢性伤口中,足跟溃疡给伤口护理人员带来了巨大挑战。这些溃疡发展为跟骨骨髓炎的可能性是众所周知的。“从伤口去除什么”这一概念是一条广为人知的临床公理;然而,广泛的清创或包括部分跟骨切除术在内的手术重建会显著损害患者的行走、平衡及整体功能活动能力。伤口愈合过程的关键在于替换受损细胞。利用细胞疗法实现伤口闭合为伤口护理专家增添了新手段。在几种市售的先进伤口产品中,美国食品药品监督管理局仅批准了1种活的双层细胞疗法(Apligraf)与标准疗法联合用于治疗静脉性溃疡以及全层神经性糖尿病足溃疡。Apligraf能够表达正常皮肤中发现的多种生长因子,从而有可能在伤口中提供具有生物活性的基质。本病例回顾总结了活的双层细胞疗法在10例足跟溃疡中的应用。使用Apligraf并进行适当的减压,实现了有效的伤口闭合,为足跟溃疡患者带来了另一种护理方案。
