Weight-bearing timing after the operative management of ankle fractures: single center audit and critical appraisal of literature.

The postoperative weight-bearing policy following internal fixation of unstable ankle fractures varies greatly and is largely surgeon-dependent. While early weight-bearing is favoured for its superior functional and economic outcomes, late weight-bearing may be safer initially. However, consensus on the preferred treatment protocol is lacking. We audited practices at University Hospitals Leuven, Belgium, comparing them to existing literature to establish an updated protocol. In a retrospective study of 236 patients with unstable ankle fractures, we compared outcomes between early (EWB) and late weight-bearing (LWB) strategies, with or without braces and/or vacuum casts. Most patients followed a LWB protocol, while EWB was reserved for younger, lower BMI individuals. The difference in brace or vacuum cast usage was insignificant. All open fractures followed a LWB protocol. No disparities in union rates, complications, or length of stay were found between EWB and LWB. Surgical management cost €6,419 (6,921 US $) on average, with length of stay being the main cost driver. Total healthcare costs did not differ significantly between EWB and LWB. FRI was revealed in 6 cases, (1 [4%] vs. 5 [2.5%], EWB vs. LWB respectively, P=0.922) In conclusion, while no significant differences in outcomes were observed between EWB and LWB rehabilitation, differences in group characteristics may have influenced these findings. Despite limited EWB cases, it appears safe for younger patients with low BMI. Vacuum casts and braces aid in EWB. Reducing length of stay, rather than restricting orthotic use, may help control healthcare costs.
