The objective of this study is to thoroughly examine the role of V.A.C. NPWT in the further salvage of the diabetic foot once it has undergone partial amputation. To determine this, measures of healing, quality of life, and utilization costs associated with this approach will be analyzed. KCI believes that information obtained from this study will show V.A.C. NPWT can support efforts involving limb salvage of the diabetic foot, helping an effective, cost-efficient healthcare solution.
