Fracture Open Tibia Clinical Trial
Official title:
A Masked, Randomized Controlled Trial Evaluating Locally-applied Gentamicin Versus Saline in Open Tibia Fractures
Local application of antibiotics directly to the traumatic wound is a promising treatment for the prevention of infection after open tibia fractures, which are a significant source of disease burden globally, particularly in low-income countries. This study aims to measure the effect of locally applied gentamicin on risk of infection for open tibial fractures in Tanzania. If proven effective, local gentamicin would be a highly cost-effective strategy to reduce complications and disability from open tibial fractures that could impact care in both high- and low-income countries.
Tibial shaft (shinbone) fractures are the most common major fracture of the lower leg and are frequently associated with a break in the skin known as an open fracture. Because the bone is exposed by the open wound, open tibial fractures are often complicated by infection and failure of bone healing, which can lead to long-lasting disability and in some cases amputation. Intravenous antibiotics administered early after injury are a well-established measure to prevent fracture-related infection (FRI), but their effectiveness is limited by poor blood flow at the fracture site and inability to achieve high local concentrations with systemic administration. Gentamicin applied locally within the open fracture wound is a promising adjunctive measure to reduce the risk of FRI after these injuries, but there are no high-quality clinical trials evaluating its use. This will be the first randomized trial evaluating locally administered gentamicin to reduce infection in a fracture population. If efficacious, local gentamicin is likely to be a highly cost-effective preventive strategy for FRI and may ultimately be cost saving. Although these findings will originate from a low-income country, results may be generalizable to populations in both high and low-income countries and could therefore significantly reduce the global burden of open fractures. ;
