Assembling
„
Basic structure
„
The load line (b) in below knee prostheses passes through the knee pivot point (K), in above
knee prostheses through the trochanter major (T), and intersects the foot at approx. 1/3 heel
lever, 2/3 forefoot lever (Fig. 1). Individual patient circumstances (e.g. flexion contracture) must
be considered in the subsequent course.
Static trial fitting
„
The prosthesis structure and component alignment must be adjusted to obtain even weight
distribution on the forefoot and heel while the patient stands with an even load on both feet
(Fig. 2). Here the heel height is 0 mm to max. 10 mm.
Then check the load line to determine whether it corresponds to the recommended starting
point (Fig. 3).

Technical Notes
„
Disassembly/assembly of the cosmetic foot cover
„
The 5M400 Shoe horn makes it easier to slide the prosthetic foot in and out of the cosmetic
foot cover.
Disassembly
„
Make sure that the heel projects over a table edge during disassembly. This permits the heel to
be levered out of the cosmetic foot cover, which makes doffing easier (Fig. 4, similar).
Modifications during adjustment
Tilt the foot in the plantar flexion direction or
move the load line back
Tilt the foot in the dorsal extension direction or
move the load line forward
Tilt the foot in the dorsal extension direction or
move the load line forward
Tilt the foot in the plantar flexion direction or
move the load line back
