plaster in a spiral motion overlapping each layer
by one-third to one-half. Smooth out the layers
with a gentle palmar motion. When applying the
plaster, make tucks by grasping the excess material
and folding it under as if making a pleat. Suc-
cessive layers cover and smooth over this fold.
When the plaster is anchored on the wrist, cover
the hand and the palmar surface before continuing
up the arm (figs. 5-4D and 5-4E). Repeat this pro-
cess until the cast is thick enough to provide ade-
quate support, generally 4 to 5 layers. The final
step is to remove any rough edges and smooth the
cast surface. The ends of the cast are turned back
and covered with the final layer of plaster, and
the plaster is set for approximately 15 minutes and
then trimmed with a cast saw as needed.
LONG-ARM CAST. The procedure for a
long-arm cast is basically the same as for a short-
arm cast except the elbow is maintained in a 90°
position, the cast begins at the wrist and ends on
the upper arm below the axilla, and the hand is
