Diabetic foot ulcers occur in up to 15% of all diabetic patients and are a leading cause of nontraumatic amputation worldwide. Neuropathy, abnormal foot biomechanics, peripheral vascular disease and external trauma are the major contributors to the development of a foot ulcer in the diabetic patient. Therapy today includes repeated debridement, offloading, and dressings, for lower grade ulcers, and broad spectrum antibiotics and occasionally limited or complete amputation for higher grades, requiring a team effort of health care workers from various specialties. The large population affected by diabetic foot ulcers and the high rates of failure ending with amputation even with the best therapeutic regimens, have resulted in the development of new therapies and are the focus of this review. These include new off loading techniques, dressings from various materials, methods to promote wound closure using artificial skin grafts, different growth factors or wound bed modulators and methods of debridement. These new techniques are promising but still mostly unproven and traditional approaches cannot be replaced. New and generally more expensive therapies should be seen as adding to traditional approaches.
糖尿病足溃疡在所有糖尿病患者中的发生率高达15%,是全球非创伤性截肢的主要原因。神经病变、足部生物力学异常、外周血管疾病和外部创伤是糖尿病患者足部溃疡形成的主要因素。目前的治疗方法包括对较轻度溃疡进行反复清创、减轻压力和包扎,对较重度溃疡使用广谱抗生素,偶尔进行有限或完全截肢,这需要各专业医护人员的团队协作。即使采用最佳治疗方案,受糖尿病足溃疡影响的人群数量众多,且截肢失败率很高,这促使了新疗法的开发,也是本综述的重点。这些新疗法包括新的减压技术、各种材料的敷料、使用人工皮肤移植促进伤口愈合的方法、不同的生长因子或伤口床调节剂以及清创方法。这些新技术很有前景,但大多仍未得到验证,传统方法也无法被取代。新的且通常更昂贵的疗法应被视为对传统方法的补充。
