6. MOUNTING AND FITTING ON THE PATIENT
A. Alignments
Preparation:
Trace the load lines and knee joint centre on the socket.
Alignment in sagittal plane:
The load line must run through the knee joint centre marked on the
socket, and 60 to 70 mm back from the blade contact point with the
ground.
The knee-ground mounting height must be 30 to 50 mm more than
the height on the patient (including shoe).
No flexum. If the patient has genuine flexum, this must be respected.
Alignment in frontal plane:
The construction line must run via the middle of the socket and the
middle of the blade (the blade must have a few degrees' external
rotation).
Finishing:
After setting and alignment, glue the screws (XC047 medium
threadlock), and torque tighten to 6 Nm.
B. Alignments (with the patient)
1. Jumping from one foot to the other: the blade must press flat on
the ground (frontal view).
2. Hopping: the blade must drive upwards (not to the front or rear). If necessary, modify the blade angle. In every case, the patient
must feel that their knee is free-moving and easy to control (no hyperextension caused when the blade is pressed on the
ground).
3. Running tests: the objective is to limit muscle and ligament stress, and reduce the patient's energy consumption. To do so, you
can adjust the height, and the frontal and sagittal angles, according to how the patient feels. The aim is to obtain stride symmetry
at the patient's running speed.
•
Feeling of sinking, too much give: the blade module is probably too flexible. Check when the patient is running with
small strides on an upward slope; if there is no reaction force, the blade is too flexible.
•
Patient feeling impacts, discomfort: the blade module is probably too stiff.
•
Patient feeling outward or inward tilting of the prothesis: the blade is probably too far inward or outward.
•
Patient experiences falling sensation before contact (shoulder dropping): The prothesis is probably too short.
•
Patient feeling difficulty striding: the prothesis is probably too long.
C. Setting the pyramidal connector
Modifying the orientation of the pyramid, or replacing the connector:
•
Loosen or remove the connector.
•
Adjust the orientation, and then refit or retighten, applying some
threadlock glue on the taps of the lower connector.
•
Torque tighten to 6 Nm.
7. DETECTING MALFUNCTIONS
If you observe abnormal behaviour or feel modifications in the device's
properties, or if it undergoes a heavy impact, please consult your orthopaedic prosthetist.
Action: replace the module. For a fine adjustment, you can move the blade forward in relation to the socket.
Action: replace the module. To fine-tune, you can move the blade backward in relation to the prothesis.
Action: incline it in the direction of the valgum/varum, or shift it across.
Action: increase the height of the prothesis.
Action: decrease the height of the prothesis.
