Prosthetic Alignment Helper
Enter socket flexion, pylon, and foot progression angles to compute resultant prosthetic alignment deviation and check clinical acceptance ranges.
Alignment Inputs
All angles in degrees. For certified prosthetist/orthotist reference use only.
Enter alignment angles and click Calculate
to see results and clinical acceptance status.
Alignment Summary
Parameter Assessment
| Parameter | Value | Accepted Range | Status |
|---|
Clinical note: Accepted ranges are based on standard prosthetist education references (e.g., Atlas of Limb Prosthetics). Flagged values indicate deviation from typical bench alignment guidelines and should be evaluated by a qualified certified prosthetist or orthotist (CPO) in the context of each patient's clinical presentation. This tool does not account for dynamic alignment adjustments.
Summary
Enter socket flexion, pylon, and foot progression angles to compute resultant prosthetic alignment deviation and check clinical acceptance ranges.
How it works
- Select the prosthesis type: transtibial (below-knee) or transfemoral (above-knee).
- Enter the socket flexion angle (degrees of flexion built into the socket).
- Enter the pylon angle in the sagittal plane (positive = anterior tilt) and coronal plane (positive = medial tilt).
- Enter the foot progression angle (positive = toe-out, negative = toe-in).
- Click Calculate to see the resultant alignment deviation and a pass/flag status for each parameter.
- Use the color-coded summary to identify angles outside typical clinical acceptance ranges.
Use cases
- Verify bench alignment settings before dynamic alignment in the parallel bars.
- Document socket flexion and pylon angle choices in a patient record.
- Quickly check whether a foot progression angle is within the typical -5 to +15 degree range.
- Cross-check coronal pylon tilt against the accepted 0–5 degree medial tilt guideline.
- Educate prosthetic students on how individual angle inputs combine into a resultant deviation.
- Screen preliminary measurements before a formal clinical gait analysis session.
- Compare alignment settings between the sound and prosthetic sides.
- Use as a reference aid during remote or telehealth prosthetic consultations.
