Alignment Procedure

When aligning the prosthesis for use with the Blatchford
Hydraulic Knee controls, position of the load line is critical.
Unlike traditional alignment procedures where the load line
passes in front of the knee centre for stability, the load line
should pass slightly behind the knee centre. Aligning the limb
the prosthesis.
This is also important to the function of the Blatchford units. The
units release from stance only after a hyperextension moment
weight is still on the prosthesis. You need not be concerned
about the unstable alignment. The stance phase resistance
will prevent the knee from buckling.
The notes above also apply to the KX06 knee - (not shown)
allow the addition of pyramid based components. Pyramids
should however, be aligned so the shin components are
vertical to maximise the function of the knee.
These notes also apply to the Mercury Hi-Activity
Discontinuous shin assembly (not shown).
The wearer should be advised:
Any change in performance or function of the device must be
reported to the practitioner
e.g. unusual noises, faster or slower swing or reduced stance
support.
After running or periods of high activity the cylinder may
become very warm, this is normal.
Storage & Handling:
When storing for prolonged periods place cylinder vertically
with trunnion uppermost. Alternatively and in addition, air
management may be assisted by cycling the cylinder several
times with the stance resistance switched off (refer to 'Stirrup
functions and features'). Use product packaging supplied.
