Here, this is from an article in the Journal of the American Academy of Orthopedic surgeons:
In a prospective, randomized study, 26% of patients treated with a figure-of-8 bandage were dissatisfied compared with 7% of those treated with a sling. The patients treated with a sling reported less discomfort. There was no difference in overall healing and alignment of the fractures, indicating that a figure-of-8 bandage does little to obtain or maintain reduction.
