Is postoperative non-weight-bearing necessary? INWN Study protocol for a pragmatic randomised multicentre trial of operatively treated ankle fracture

The feasibility, acceptability, safety, and effects of early weight bearing in humeral fractures - a scoping review

PURPOSE

Non-weight bearing is often recommended after humeral fractures. This review aims to summarise the extent and nature of the evidence for the feasibility, acceptability, safety, and effects of early weight bearing (EWB) in people with humeral fractures, treated operatively or non-operatively. .

METHODS

Data sources identified published (PUBMED, EMBASE, CINAHL) and unpublished (ClinicalTrials.gov, CENTRAL, NIHR Open Research, OpenGrey) literature. Independent data extraction was conducted by two reviewers.

RESULTS

13 901 records were retrieved. Ten studies, involving 515 post-operative patients and 351 healthcare professionals, were included. EWB was found to be feasible in nine studies. There was limited evidence regarding adherence to EWB. Trauma and orthopaedic surgeons reported that EWB was acceptable. This depended on surgery type and whether it was a post-operative polytrauma case. No acceptability data was reported from patients' perspectives. Only one study reported two patients who developed unsatisfactory outcomes from excessive post-operative EWB. Positive effects of EWB were reported on disability level, pain, shoulder and elbow motion, and union.

CONCLUSION

There is some evidence for the feasibility, safety, and effectiveness of post-operative EWB after humeral fractures. There was limited data on the acceptability of EWB. Heterogeneous study designs, and variations in EWB protocols limit conclusions.

Safety of early weightbearing after ankle fracture fixation

PURPOSE

Patients with surgically treated ankle fractures are traditionally kept non-weightbearing for at least six weeks post-operatively; however, recent literature suggests numerous benefits of early weightbearing (EWB) before six weeks without significantly impacting long-term outcomes. This study aims to review the safety of early vs late weightbearing following ankle fracture fixation by assessing the complication rate.

METHODS

This was a single-centre retrospective study. Between 2020 and 2023, all ankle fixations that commenced weightbearing at two weeks were added to the EWB group. An equal number of similar patients with six-week non-weightbearing were added to the late weightbearing (LWB) group. Baseline characteristics, risk factors, types of fractures and any complications in the six-month post-operative period were evaluated from these cohorts.

RESULTS

In total, 459 ankle fixations were identified of which 87 patients met the criteria for the EWB group, with a further 87 added to the LWB group. There was no significant difference in age between the two groups (51.7 ± 20.1 vs 51.0 ± 15.5, respectively; p = 0.81), but more female patients and diabetics in the EWB group. Fracture types were similar between both cohorts (p = 0.51). Complication rate in the EWB group was not significantly different to the LWB group (5 vs 9, p > 0.05).

CONCLUSION

No increase in complication rate was identified by commencing weightbearing early at two weeks after ankle fixation compared to six weeks. We therefore suggest EWB if appropriate, given its associated benefits including restoration of patient independence and improved quality of life.
