Summary: For adults over 60 with an unstable acute ankle fracture, use of a molded below-knee cast with minimal padding (applied under anesthesia by a trained surgeon) may lead to the same functional outcomes for the ankle at 6 months as surgical internal fixation but with lower likelihood of infection and less operating room time. (However, casting may be associated with a higher rate of radiologic malunion than surgery).
