62 patients undergoing intramedullary nailing for tibial shaft fractures were randomized to postoperative protocols of either immediate weightbearing-as-tolerated (WBAT) or non-weightbearing (NWB) for 6 weeks postoperatively. Functional and radiographic outcomes were monitored up to fracture union, or until treatment failure or revision surgery was required. The results indicated that there were no significant differences between groups regarding time to union, functional outcome, or complication rate. No patient of either group was observed to have malunion due to loss of reduction.
