Historically lower limb amputations have been performed to treat infection or trauma, usually in the setting of war. Today however major amputations of the lower extremities (transfemoral- (TFA), knee disarticulations (KD) and transtibial amputations (TTA)) are, in developed countries, usually performed in elderly patients with untreatable vascular disease, diabetes or a combination of both. This fragile group of patients are characterized by a high degree of comorbidity, mortality and both surgical and postoperative complications; included herein problems with wound healing. The tissue is typically poorly vascularized and prone to wound break-down, infections, necrosis etc. 10-40% of patients undergoing TFA, KD or TTA have delayed wound healing and/or insufficient wound healing, resulting in problems with the aftercare, mobilization with a prosthesis and re-amputations. Recent retrospective studies show that Negative Pressure Wound Therapy (NPWT) may have beneficial effects on incisional healing following lower limb amputations. However to our knowledge it has never been reproduced in a prospective randomized controlled setting.The aim of this study is to investigate the effect of NPWT with a PICO®? device (Smith & Nephew) on the healing of the surgical wound following TFA, KD and TTA.
