Moulding The Femoral Condyles And Tibial Plateau - Otto Bock Harmony P3 Technical Information

3.2.2 Moulding the femoral condyles and tibial plateau

Objective
In the first phase of plaster casting the femoral condyles and the tibial plateau are moulded with a plaster splint.
The lower edge of the patella is also formed. The plaster splint is moulded by vacuum in a latex casting bag.
Moulding is carried out at a flexion angle of approx. 85° to enable easy bending of the knee when the prosthesis is
being worn.
Required tools and materials
• Plaster bandages, plaster cast scissors, 99B25 nylon stockinette, 683G1=* latex casting bag
Harmony System
Pull a nylon stockinette over the residual limb.
Optional: Add markings to facilitate modelling, for
example:
• MPT line
• Patella
• Prominent areas of residual limb
• Femoral condyles
• Distal end of the tibia
Cut a six-layer plaster splint.
INFORMATION: The plaster splint is part of the plaster
cast and remains in the cast.
Place the plaster splint on the residual limb. Place the
narrow part between the lower edge of the patella and
the tibial tuberosity.
Cut the plaster splint according to the reference points.
