CASTING The cast is taken in two sections. The first section includes the foot-ankle to the mid-calf areas. The second section includes the mid-calf area to a point above the femoral condyles. First Section (Fig. 14) 1. Patient is seated on a plinth or chair with the foot held in 5 deg. of dorsiflexion on the properly selected last. 2. Stockinette, sewn at the toes, is placed on the leg and brought above the knee. 3. The leg is brought into 5 deg. of dorsiflexion relative to the floor. 4. With the indelible pencil the patella is located and its borders marked; tibial tubercle, crest of tibia, head of fibula, lateral flare of tibia, medial condyle flare, both medial and lateral malleoli, first and fifth metatarsal heads, and any Fig. 13. The plastic PTB orthosis effectively eliminated contact between the orthosis-shoe unit and the ground. Case No. 5. FABRICATION DETAILS MATERIALS AND EQUIPMENT FOR CASTING NEEDED Two rolls of elastic plaster bandages Cotton stockinette 3 in. wide, to place over knee down to and including the foot Indelible pencil Water in basin 6 in. deep Surgical tubing or webbing strip Cast cutter Bandage shears Yardstick Tape measure Ritz stick Measurement chart Casting lasts for matching heel height of shoe to orthosis Fig. 14. The major bony landmarks are outlined on the cotton stockinette; elastic plaster-of-Paris bandage is used to wrap the foot while it is positioned on a last.
other pertinent bony prominences. The midpoint of the patellar tendon is also marked (Fig. 14). 5. A strip of surgical tubing is placed along the medial side of the knee and down the anterior midline of the leg, extending to the toes, to permit removal of the cast later (Fig. 15). 6. Elevate the foot and wrap with elastic plaster bandage going to the mid-calf level. 7. Replace the foot on the last and hold in the correct position until plaster has hardened (Fig. 14). Second Section 1. After the foot-ankle cast has hardened sufficiently, extend the knee to 30 deg. of flexion. 2. Wrap from the mid-calf area to a point above the femoral condyles with the second plaster-of-Paris bandage. 3. Locate the patellar tendon and popliteal fossa, and compress as is done regularly for any PTB casting procedure. 4. After the plaster has hardened, several horizontal orientation lines are placed along the outline of the surgical tubing. Removal of the cast is now accomplished by cutting down the outline of the surgical tubing with a cast cutter (Fig. 15). The hash lines are used to reestablish the cast, which is then filled with plaster of Paris (Fig. 15). The plaster bandage is stripped off in the conventional manner. MEASUREMENTS The measurements required are: • Calf circumference • Ankle circumference • Femoral condyles width • Malleoli width • Height from floor to mid-patellar-tendon level • Anteroposterior width of knee at midpatellar-tendon level Fig. 15. The negative wrap has been removed. Note the patellar-tendon indentions and cast reference lines. Fig. 16. The completed negative wrap is ready forfilling with plaster of Paris.
