Amputation Clinical Trial
Official title:
The Effect of Negative Pressure Wound Therapy on Wound Healing in Major Amputations
The socioeconomic costs of problematic and delayed wound healing following lower limb amputations are enormous to the society. Lower limb amputations is one of the longest known surgical treatments, but also one of the least investigated in the field of medical science. Negative Pressure Wound Therapy (NPWT) has emerged as a great instrument to aid healing. Studies have shown that it has a positive and measurable effect on wound healing following eg. total Knee and hip replacements. The aim of this study is to evaluate the effect of a closed NPWT on incidence of postoperative wound complications, in patients undergoing lower extremity amputation.
