Apply 2 layers of 6” soft roll with
each layer overlapping by 1/2 the
diameter or 3”. Make sure that
any bony prominences and the
heel are well padded.
Using 6” fibreglass cast material apply from the proximal interphalangeal joints to the tibial tuberosity.
Overlap the cast material by 1/2 the diameter or 3”. Ensure the lower extremity is in a neutral position with no dorsiflexion / plantar flexion or inversion / eversion.
Set the height of
the device so that the distal aspect
sits near the widest portion of the
gastrocnemius when the device
has approximately 2.5”-3” of
clearance below the calcaneus.
Set the width of the device so that
the stirrup sits comfortably over the
cast.
It is ok for the Alger Unloader
to be slightly wider than the cast
as the next layer of cast roll
will compress both sets
of proximal tabs to the cast.
Apply one layer of 6” soft roll around
proximal tabs and upper stays of
The Alger Unloader.
Make sure the stirrup is at a neutral
axis in the sagittal and frontal plane.
The stirrup should be aligned to the
longitudinal axis of a lower extremity.
Ensure that the stirrup sits
approximately 2.5” – 3” below the
plantar surface of the fibreglass cast.
Place two layers of 6” fibreglass cast material around the proximal tabs of the stirrup in order to
secure it in place.
Allow the fibreglass to dry completely prior to commencing weight-bearing.
