When deflecting the side bars for external roatation, what is the maximum deflection for the medial side bar before the lateral bar must be deflected?
What are calf bands used for on KAFO?
Used to maintain spatial relationship between the distal side bars
Uses larger circumference than an AFO calf band
Is located more distal than with an AFO
When contouring a solid stirrup, what must be added to the heel width to make the correct contour?
3mm to each side
How is solid stirrup length determined?
Medial malleolus + sole thickness)x2 + heel width + 6mm = stirrup length
When preparing a stirrup for a patient with a fixed deformity, how do you determine the discrepency?
Measure the distance between the ankle center and the center of the calcaneous
When determining the offset for a fixed valgus deformity, to what side of the stirrup should the center point be moved?
that is associated with a calf band used on a metal KAFO
65% of circumference
Structural member of the system
Tilted to match calf band
Why are three millimeters added to the amount of deflection when contouring side bars to accommodate for external rotation?
Because 11 mm of clearance is added to the anatomical ankle diameter for joint clearance
When tilting the calf band, how is the tilt determined to match the contour of the patient's calf?
Difference between the circumferences and divide by four
What distance from the neck of the fibula should the proximal edge of the calf band be located on a KAFO
Toe in/out measurement is incorporated into____________________ while the tibial torsion measurement is incorporated into____________________________.
Attachment of shoe to stirrup: Anterior deflection of medial sidebar
