Please give 5 minutes of your time to provide your opinion on the most important outcomes to collect in patients with open lower limb fractures (OLLF). Outcome concepts for OLLF have been developed from in-depth interviews with patients and from a review of the published literature. Through the link above you will be able to complete a Delphi survey where you will score the importance of these outcome concepts.
