The AIM trial is a pragmatic multi-centre randomised controlled trial comparing Close Contact Casting technique (CCC) to Open Reduction and Internal Fixation (ORIF) surgery in the treatment of unstable ankle fractures in patients over 60 years of age.
The trial was designed to establish whether CCC is clinically equivalent to ORIF for management of unstable ankle fractures in terms of function, complications, quality of life and patient satisfaction.
AIM is an academic research study sponsored by the University of Oxford and led by Professor Keith Willett. AIM is funded by the NIHR Health Technology Assessment programme.
