Detailed Description
The primary objective of early open fracture management is to minimize the risk of complications. In severe cases, multiple irrigation and debridement surgeries are required to overcome the severe wound contamination, to reassess the evolving tissue injury, and/or to temporize and plan appropriate soft tissue coverage with a skin graft or muscle flap. When multiple irrigation and debridement surgeries are needed, there is uncertainty on how the open fracture wound should be managed between procedures. Negative pressure wound therapy (NPWT), commonly known as a Wound VAC, is the preferred method of open fracture wound management for most surgeons. Opponents of NPWT believe that NPWT desiccates the open fracture wound and rapidly removes any local antibiotics placed in the wound during surgery. Instead of using NPWT, they place temporary non-absorbable antibiotic-laden cement beads into the open fracture wound and seal it with a large occlusive dressing. This wound management strategy is known as an antibiotic cement bead pouch, or more commonly a Bead Pouch. Mounting evidence questions the effectiveness of NPWT to prevent open fracture complications. Additionally, emerging comparative studies suggest the antibiotic bead pouch may significantly reduce the risk of infection compared to NPWT. This trial seeks to fill this critical knowledge gap.
The primary objective of this trial is to determine if the antibiotic bead pouch, compared to NPWT application, is more effective at reducing open tibia fracture complications. The primary outcome will be a composite outcome to evaluate clinical status six months after randomization. Components of the composite outcome will be hierarchically assessed in the following order: 1) all-cause mortality, 2) injury-related amputation of the lower extremity, 3) unplanned reoperation to manage wound complications, infection, or delayed fracture healing, and 4) clinical fracture healing as assessed using the Functional IndeX for Trauma (FIX-IT) instrument. The secondary objectives will independently assess the four components of the primary outcome.
The trial population includes patients 18 years and older with a severe open tibia fracture requiring more than one irrigation and debridement and being treated with internal or external fixation for definitive fracture management. Patients who have contraindications to the NPWT or local intrawound antibiotics will be excluded.
312 participants will be randomized in a 1:1 ratio to receive either an intraoperative antibiotic bead pouch or negative pressure wound therapy (NPWT). Participants will receive their allocated wound management strategy at the conclusion of their first irrigation and debridement procedure. Participants will have follow-up assessments at 6 weeks, 3 months and 6 months post-fracture.
The primary outcome will be a composite outcome to evaluate clinical status six months after randomization. Components of the composite outcome will be hierarchically assessed in the following order: 1) all-cause mortality, 2) injury-related amputation of the lower extremity, 3) unplanned reoperation to manage wound complications, infection, or delayed fracture healing, and 4) clinical fracture healing as assessed using the Functional IndeX for Trauma (FIX-IT) instrument. The secondary outcomes will independently assess the four components of the primary outcome. An Adjudication Committee will review all primary and secondary endpoints and a Data Safety Monitoring Committee (DSMC) will review all safety events.

Eligibility Criteria
Ages Eligible for Study

Description
The inclusion criteria are:
- Patients 18 years of age or older.
- Severe open tibia fracture requiring more than one irrigation and debridement procedure to treat the open fracture.

- Formal surgical debridement within 72 hours of their injury.
- Will have all planned fracture care surgeries performed by a participating surgeon or delegate.
- Informed consent obtained.
The exclusion criteria are:
- Due to the severity of injury, the treating surgeon does not believe limb salvage >6 months is likely to be successful based on the emergency department or initial intraoperative assessment (prior to enrolment and randomization).
- Medical contraindication to antibiotic beads.
- Medical or injury contraindication to NPWT. Injury contraindications could include situations in which the NPWT could not be placed over a vascular graft or exposed neurovascular structure.

- Chronic or acute infection at or near the fracture site at the time of initial fracture surgery.
- Incarceration.

Experimental: Antibiotic Cement Bead Pouch
The antibiotic cement bead pouch involves placing temporary non-absorbable antibiotic-laden cement beads into the open fracture wound and sealing the wound with a large occlusive dressing for prophylaxis against bacteria. The antibiotic beads used will be prepared intraoperatively by the surgical team. The bead recipe will be comprised of a ratio of 2 grams of vancomycin, 2.4 grams of tobramycin, and 40g (one bag) of PMMA cement. The beads will be handmade and approximately 10-mm in diameter. The number of beads placed in the wound will be at the discretion of the treating surgeon based on recipient wound size. As commonly practiced, the antibiotic beads may be exchanged for new beads at each subsequent irrigation and debridement surgery. The number of beads, the number of replaced beads, and the removal of the antibiotic beads will be recorded. |
The antibiotic bead pouch provides an antibiotic delivery mechanism.
It is made by combining polymethyl methacrylate (PMMA) cement with generic forms of vancomycin and tobramycin powder.

Active Comparator: Negative Pressure Wound Therapy (NPWT)
The NPWT system is a sealed dressing placed over the open fracture wound that includes an occlusive plastic wound dressing connected to a vacuum pump, tubing, and a canister to collect fluid. The pump creates a vacuum seal and exerts negative pressure on the wound to remove fluid and maintain a sealed environment. NPWT promotes wound healing through four primary mechanisms: 1) wound shrinkage or macrodeformation; 2) microdeformation at the foam-wound surface interface; 3) fluid removal; and 4) stabilization of the wound environment. 125 mmHg continuous negative pressure is the recommended NPWT device setting; however, the treating surgeon will be allowed to adjust these settings as clinically necessary. The frequency and timing of NPWT changes will also be at the surgeon's discretion but is expected to primarily coincide with the timing of repeat debridement, typically every 24-72 hours until definitive management has occurred. |
