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. Successive 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 process until the cast is thick enough to provide adequate 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 not wrapped.
SHORT-LEG CAST. In applying a short-leg cast, seat the patient on a table with both legs
