dLocal antibiotics consisted of either gentamicin-loaded beads, cement, or bioresorbable films in both protocols and were administered at assessment of the treating physician
eOverlap with secondary closure and skin or flap transplantation
fOutliers in wound closure in both groups were due to small skin defect with diminished wound-healing tendencies. Vacuum or antibiotic therapy was not indicated for the total duration needed for closure
