Task 1 Competency 3

Lay Out the KAFO for Fabrication


Objective
Objective

  • Supplied with a full leg tracing and a completed orthometry form you will create a “blueprint” to be used when fabricating the metal AFO


Correct ankle dimensions
Correct Ankle Dimensions

  • Identify and mark the apices of the medial and lateral malleoli

  • Lay out a line passing through the marks

  • Measure the width of the tracing between marks and mark midpoint


Correct ankle dimensions1

½ measured M-L

½ measured M-L

Correct Ankle Dimensions

  • Measure out ½ the measured M-L from the orthometry form from the center and mark


Correct ankle dimensions2
Correct Ankle Dimensions

  • Redraw ankle region, blending in with original tracing


Correct ankle dimensions3

1 ¼”

Correct Ankle Dimensions

  • Measure medially from medial malleolus 1 1/4” and mark


Correct knee dimensions
Correct Knee Dimensions

  • Find approximate knee joint center and draw horizontal line


Correct knee dimensions1
Correct Knee Dimensions

  • Determine midpoint of tracing

  • Measure out ½ the measured M-L from the orthometry form from the center and mark


Correct knee dimensions2
Correct Knee Dimensions

  • Redraw knee region, blending in with original tracing


Correct knee dimensions3

5/8”

Correct Knee Dimensions

  • Measure medially from medial knee 5/8” and mark


Determine mid saggital line
Determine Mid-Saggital Line

  • Draw a line beginning at the perineum and passing through the knee and ankle marks


Determine mid saggital line1
Determine Mid-Saggital Line

  • Genu Valgum is indicated if the line passes through the knee mark but outside the ankle mark


Determine mid saggital line2
Determine Mid-Saggital Line

  • Genu Varum is indicated if the line passes outside the knee mark and through the ankle mark


Lower section heights and locations
Lower Section Heights and Locations

  • Heel base

  • Shoe thickness

  • Ankle joint axis

  • Fibular head

  • 1 ½”below fib. head (prox. edge of calf band)

  • 1 ½” below mark #5 (distal edge of calf band)

  • Medial tibial plateau

Upper section heights and locations
Upper Section Heights and Locations

  • Distal edge of distal thigh band (same distance from KC as prox. calf band)

  • 1 ½” above mark #10

  • Perineum

  • Transfer mark #12 to lateral side of tracing

  • 1 ½” below perineum

1/8”

Ankle Joints and Stirrup

  • Measure out 1/4” medially and 3/16” laterally from previous marks to create minimum clearance

  • Measure out another 1/8” on each side to compensate for ankle joint thickness

  • Project lines perpendicular to ankle axis extending from 2” superior to axis down to heel thickness line. The stirrup will be shaped along these lines

Knee Joints

  • Measure out 1/4” medially and 1/8” laterally for minimum knee joint clearance


Calf band widths
Calf Band Widths

  • Measure the width of the tracing along calf band lines and mark midpoints

  • Measure out ½ the measured M-L s from the orthometry form from the centers and mark

Calf band widths1
Calf Band Widths

  • Measure out and mark 1/8” from established M-L to accommodate padding

  • Measure out and mark an additional 1/8” to accommodate band thickness

  • Connect the outer marks proximally to distally. The band will be contoured to the inside of these lines

Knee

Proximal and distal thigh band widths
Proximal and Distal Thigh Band Widths

  • Measure the width of the tracing along the distal edge of the distal thigh band and the proximal edge of the proximal thigh band. Mark the midpoints
