Dynamic Valgus Angle Screen
Compare the measured value with caller-supplied bounds for dynamic valgus angle screen.
Description
Dynamic-valgus angle screening applies a caller-selected range to an upstream measurement.
Dynamic-valgus angle screening applies a caller-selected range to an upstream measurement. Signed margins report distance from each edge.1
Compare the measured value with caller-supplied bounds for dynamic valgus angle screen.
When to use Dynamic Valgus Angle Screen
Use this tool to compare the measured value with caller-supplied bounds for dynamic valgus angle screen.
Prepare the measured movement, timing, load or preassigned score requested. Keep protocols, units, paired measurements and caller-selected thresholds consistent.
How to use Dynamic Valgus Angle Screen and understand its results
- Prepare the measured movement, timing, load or preassigned score requested. Keep protocols, units, paired measurements and caller-selected thresholds consistent.
- Enter valgusAngleDegrees, minimumAngleDegrees, maximumAngleDegrees using the field table and calculation rules, then run the tool.
- Read marginToMaximum, marginToMinimum, withinRange. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| valgusAngleDegrees | Dynamic valgus angle (°) | number | Required |
| minimumAngleDegrees | Minimum accepted angle (°) | number | Required |
| maximumAngleDegrees | Maximum accepted angle (°) | number | Required |
Enter finite signed degree values with ordered bounds. Return margins and inclusive within-range flag.
minMargin=angle−minimum; maxMargin=maximum−angle Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| marginToMaximum | Margin to maximum (°) | number |
| marginToMinimum | Margin to minimum (°) | number |
| withinRange | Within range | boolean |

}Limitations and assumptions
No imaging, 2D-to-3D correction, anatomical convention or injury-risk model is supplied.
Numeric inputs must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors. A successfully returned false flag is an evaluated outcome; its meaning is explained above.
