*Data for all follow-up times, for each outcome measure, shown in tables B-I in appendix.

†Data for 12 week follow-up for full weight bearing and 18 week follow-up for radiographic healing and ≥80% of function before injury, as almost all patients in both groups had achieved these outcomes at 52 weeks.
