Weight-Bearing Status Before Surgical Evaluation
The patient should be instructed to weight-bear as tolerated (WBAT) with appropriate assistive devices until evaluated by a surgeon, unless there is a clear contraindication such as an unstable fracture pattern or severe soft tissue injury.
Clinical Reasoning
The evidence strongly supports early weight-bearing across multiple fracture types, and restricting weight-bearing unnecessarily can lead to worse functional outcomes, delayed recovery, and increased complications.
Hip Fractures
For hip fractures specifically, the AAOS guideline 1 demonstrates that immediate, full weight-bearing to tolerance after surgery is the standard of care (limited strength of evidence, limited strength option). The guideline case examples consistently show patients mobilized with weight-bearing as tolerated immediately postoperatively. Recent audit data 2 confirms that 93.2% of hip fracture patients in England, Wales, and Northern Ireland are managed with full weight-bearing, and the authors emphasize that "full weight-bearing should become the default approach."
Ankle Fractures (Extrapolating Pre-operative Guidance)
While the robust evidence for ankle fractures addresses post-operative protocols, the principles are instructive:
- Multiple high-quality RCTs demonstrate that early weight-bearing is superior to prolonged non-weight-bearing 3, 4, 5, 6
- The most recent 2025 INWN trial 3 showed immediate weight-bearing resulted in better functional outcomes (OMAS 43 vs 35, p=0.005), faster return to work, and similar complication rates
- Early mobilization prevents joint stiffness, muscle atrophy, and DVT risk
Practical Algorithm
Pre-operative weight-bearing instructions should be:
Default to WBAT with crutches or walker for most lower extremity fractures awaiting surgical evaluation
Restrict to non-weight-bearing ONLY if:
- Grossly unstable fracture pattern visible on imaging
- Severe soft tissue compromise or open fracture
- Neurovascular compromise
- Surgeon explicitly instructs otherwise after review
Provide appropriate assistive devices (crutches, walker, boot if available)
Common Pitfalls to Avoid
- Reflexive non-weight-bearing orders: Many providers default to NWB "to be safe," but this actually increases complications including DVT, muscle atrophy, and delayed functional recovery
- Assuming all fractures need NWB: Even displaced fractures can often tolerate protected weight-bearing until definitive fixation
- Inadequate pain control: Patients need adequate analgesia to participate in WBAT safely
Important Caveats
The surgeon who will perform the definitive procedure should make the final determination about weight-bearing restrictions based on fracture pattern, patient factors, and planned surgical approach. However, the default should be permissive rather than restrictive unless there is a specific reason to restrict weight-bearing.
For hip fractures specifically, given that post-operative protocols universally support immediate weight-bearing 1, 2, there is no physiologic rationale to enforce strict non-weight-bearing pre-operatively in most cases, as this only delays mobilization and increases complications.
