Open Fractures of the Tibia:

- See: - Infections of the Tibia: - Preoperative Antibiotics; - therapeutic doses of ancef and tobramycin for 48 hrs are appropriate; - despite the added cost, tobramycin is more effective against Pseudomons and has been shown to have lower incidence prevalence of nephrotoxicity; - tetanus prophylaxis if appropriate; - Soft Tissue Defects: - initial wound care: - debridement: - consider debriding the wound with a separate set of surgical instruments / drapes - in most cases, the surgeon will elect to loosely close any incisions made during the case but to leave the traumatic wound open; - leaving the wound open maximizes drainage and wound tension (which is frequently present w/ primary closure); - at second look debridement (at 48-36 hours), the edema will have diminished and the wound can be closed w/ less tension; - references: Primary or delayed closure for open tibial fractures. - wound dressings: - antibiotic bead pouch: - as noted by Keating et al 1996, bead pouches help reduce the infection rate in open tibia fractures from 16% to 4%; - add 2.4 gm of tobramycin per cement package, and fashion small beads attached to a O silk suture; - counting the beads and adding methylene blue helps ensure that none of the beads will be left behind at removal; - a small drain is left adjacent to the beads and the wound is sealed w/ Opsite; - references: Reamed Nailing of Open Tibial Fractures: Does the Antibiotic Bead Pouch Reduce the Deep Infection Rate?
