Assessment Form
Use the fields below to mirror the ankle and foot rule findings. Results appear above this form after submission.
Example Data Table
| Case | Malleolar Pain | Midfoot Pain | Key Findings | Helper Output |
|---|---|---|---|---|
| Case A | Yes | No | Lateral malleolus tenderness, cannot bear weight, cannot walk four steps | Ankle imaging suggested |
| Case B | No | Yes | Navicular tenderness, able to bear weight | Foot imaging suggested |
| Case C | Yes | No | No malleolar tenderness, able to bear weight, walks four steps | No routine ankle imaging trigger |
| Case D | Yes | Yes | Open deformity with numbness and cold foot | Urgent assessment advised |
Formula Used
This tool uses decision logic rather than arithmetic scoring. The output follows the ankle and foot rule structure and then adds safety overrides.
Ankle imaging logic
Ankle X-ray Suggested = Malleolar Zone Pain AND (Medial Malleolus Tenderness OR Lateral Malleolus Tenderness OR Weight-Bearing Criterion)
Foot imaging logic
Foot X-ray Suggested = Midfoot Zone Pain AND (Navicular Tenderness OR Base of 5th Metatarsal Tenderness OR Weight-Bearing Criterion)
Weight-bearing criterion
Weight-Bearing Criterion = (Cannot Bear Weight Immediately) AND (Cannot Walk Four Steps Now)
Safety override
Urgent Assessment = Open Injury/Deformity OR Neurovascular Concern OR High-Energy Trauma OR Marked Clinical Worsening
How to Use This Calculator
- Enter patient details such as age, injury side, and time since injury.
- Mark whether pain is in the malleolar zone, midfoot zone, or both.
- Check the exact tenderness sites found on examination.
- Record whether the patient could bear weight immediately and walk four steps now.
- Flag neurologic issues, deformity, numbness, vascular concerns, or major trauma.
- Press Evaluate Helper Criteria to show results above the form.
- Review the chart and summary, then export the case as CSV or PDF if needed.
Frequently Asked Questions
1) What does this helper actually do?
It organizes ankle and midfoot examination findings into a structured recommendation about whether radiography may be indicated. It also highlights red flags and situations where direct clinical judgment matters more than the rule.
2) Does a negative result rule out every fracture?
No. A negative helper result lowers concern under the entered criteria, but it does not replace clinician examination, follow-up, repeat assessment, or imaging when symptoms worsen or the story is concerning.
3) Why are ankle and foot decisions shown separately?
The ankle and foot portions use different pain zones and tenderness landmarks. A patient may trigger one, both, or neither. Showing them separately makes documentation clearer and improves bedside decision support.
4) What counts as inability to bear weight?
For this helper, the weight-bearing criterion is triggered when the patient could not bear weight immediately after injury and also cannot walk four steps during the current assessment.
5) Can I use this several days after the injury?
It is most useful for acute injuries. If the case is older, worsening, recurrent, or clinically unusual, the page warns that the helper may be outside typical validated use.
6) Does swelling alone trigger imaging here?
No. Swelling can support concern, but this helper mainly evaluates pain location, bone tenderness, and the weight-bearing criterion. Clinical judgment still matters when swelling is marked or symptoms evolve.
7) When should urgent care be sought immediately?
Seek urgent evaluation for open injury, obvious deformity, numbness, cold foot, weak pulses, high-energy trauma, or worsening function. Those situations can need rapid imaging and specialist review.
8) Can this be used for children?
This page marks cases under age five as validation-limited. For pediatric injuries, especially in younger children, direct clinical assessment is important even when a rule-based screen looks reassuring.
Practical Notes
- This page is a helper for documentation and structured screening.
- It does not confirm fracture type, ligament injury severity, or return-to-sport timing.
- Consider reassessment when pain, swelling, gait, or neurovascular status changes.
