BIOSTEP CL, BIOSTEP PRO, BIOSTEP XT: fitting and alignment instructions
Static alignment
Divide the socket in half.
The midline of the socket should run 25-50 mm anterior
to the midline of the male pyramid with top of pyramid
parallel to the ground with a 10 mm heel rise.
For the initial bench alignment run the midline of the
socket through the front of the top pyramid bolt as
shown.
Dynamic alignment
Adapt the prosthetic alignment adjustments and/or sliding adjustments in order to
ensure correct heel contact, easy roll-over, and optimal shifting of weight onto the
contralateral side. For transtibial amputees please ensure there is physiological knee
flexion during stance phase.
