enough to reach from the proximal trimline to the distal end of the
residual limb. (Figure K)
2. Prepare the proximal slab, a 20cm, 4-ply slab of POP bandage long
enough to wrap fully around the waist.
3. Prepare the distal slab, a 15cm, 6ply slab to close the distal end.
4. Prepare the perineal slab, a 15 cm, 6 ply slab of POP bandage long
enough to reach from the full circumference of the proximal trim-
lines.
Plaster of Paris (POP) application
1. Apply the lateral slab to the residual limb and form firmly. (Figure L)
2. Wrap the proximal slab around the thigh and waist. Reinforce proxi-
mal slab by wrapping with a 15cm bandage; continue around contral-
ateral hips to aid lateral shaping. (Figure M)
3. Wrap remainder of the residual limb with a 15cm bandage.
4. Close the distal end with a 6 ply slab of plaster Paris bandage.
(Figure N)
5. Position residual limb in abduction.
a. Apply the perineal slab, locate middle against perineum.
(Figure O)
b. Anterior: Cover inguinal fold cross above greater trochanter.
c. Posterior: Cover ischial tuberosity well, follow proximal to gluteal
grease cross above greater trochanter.
d. Position residual limb in slight flexion and adduction.
e. Ensure pelvis is level.
6. Locate hands to reinforce proximal shape. (Figure P)
a. Hand 1: Use web between thumb and forefinger to relieve
adductor longus tendon. Reinforce ischial control area with
fingers.
b. Hand 2: Mould lateral wall around greater trochanter and lateral
femur.
Note: If ischial tuberosity can not be reached, position hand more
vertically and use fingertips to reinforce ischial control area.
7. Once plaster has fully set carefully remove negative cast, and cut
shorts to help removal. (Figure Q)
a. Mark alignment reference lines for socket set-up.
b. Fill the cast with Plaster of Paris in preparation for modifica
tion.
MODIFICATION
1. Remove any ridge present over the series of Seals. (Figure R)
2. Transfer alignment reference lines to the positive.(Figure S)
a. Ensure all landmarks transfer to positive.
b. Mark the AP/ML orientation lines.
3. Check length and circumference measures. Check AP and ML 4.
measures. (Figure T)
4. Define anterior trimline.(Figure U)
5. Define lateral trimline.(Figure V)
a. Reduce cast above and posterior to trochanter by 1cm.
b. Define posterior/medial trim line.
c. Define the medial trim-line.
6. Relieve adductor longus tendon and pubic ramus. (Figure W)
7. Check circumference measure. (Figure X)
8. Calculate volume reduction. Recommended 1-3% proximally, reduc-
ing to 0% distally. (Figure Y)
NOTE: Volume is one of the most important features of the socket.
Ensure all measurements are accurate. Reduce the model to the
calculated reductions, material may be removed from the following
areas:
• Posterior/lateral corner
• Anterior femoral triangle (scarpas triangle)
• Along lateral femoral shaft avoiding distal femur
