What this Trial Is About
This study examines the environmental impact of two common treatments for hand fractures (metacarpal shaft fractures): surgery and non-surgical care. Healthcare contributes significantly to climate change, and orthopedic surgery in particular can generate substantial greenhouse gas emissions. Although surgery is frequently used for these fractures, it is not always clearly more effective than non-surgical treatment, and the difference in environmental impact between these options is not well understood. In this study, researchers will measure and compare the carbon footprint of each treatment pathway, from injury through one year of follow-up. This includes emissions related to medical equipment, energy use, medications, and waste. The goal is to calculate the difference in environmental impact between treatments and to highlight key sources of emissions. The findings may help guide more sustainable healthcare practices without compromising patient care.
