Performance Steps
CAUTION: If capillary refill is delayed for more than 2 seconds inform physician and follow physician's
instruction.
6. Gather equipment to include scissors, thermometer, goniometer, ruler and bucket of tepid water
w/ plastic bag. Place on work cart or station.
CAUTION: The temperature of the water must be tepid ( 70-80 degrees) to reduce further injury
(possible burns) to the patient. The technician should draw room temperature water and initially use a
thermometer to gauge water temperature.

CAUTION: The technician must change the water after each application as the residue in the cast
bucket will act as an accelerator causing the casting material to increase in heat emission.

7. Assemble materials to include webril, plaster rolls, examination gloves, hospital pad (chux), bed
sheet, sling, plaster reinforcement sheet, alcohol pads/damp towel. Open and remove (5) plaster
rolls from packages and place on work cart/station.
NOTE: Physician's order, technician's preference, availability of supplies, and/or patient's extremity size
will determine which casting material (fiberglass/plaster) will be used.
8. Prepare stockinette.
NOTE: Stockinette is generally used for all casts except on patients who have had recent surgery,
recently reduced fractures, technician's preference or as directed by the physician. Stockinette and webril
are forms of protection against the exothermic reaction of the casting materials .
a. Place hospital pad or bed sheet on patient's lap.
NOTE: All patient's should be given a covering( e.g. chux, bed sheet) to reduce damaging their clothing
during the casting process.
b. Place work cart with orthopaedic bump at edge of bed.
NOTE: Technician preference will determine if orthopaedic bump is used. A number of props may be use
( e.g. L stand, finger trap stand, nursing assistant )
c. Place patient's uninjured elbow on the orthopaedic bump at a 45 degree angle to the upper
torso.
NOTE: Measurements are taken on the uninjured arm to prevent further pain or discomfort to the patient.

NOTE: Instruments of measurements may vary (e.g. tape measure, ruler, or webril).
d. Measure from 1 inch distal to the thumb to the axilla region to obtain stockinette length.
e. Pull down stockinette from stockinette container and cut measured length.
f. Roll the stockinette into a cuff leaving a 1-2 inch border at the distal edge. Place on work
cart/station for later use
9. Prepare plaster reinforcement splint for the radial aspect of the cast.
NOTE: The radial aspect of the arm is located on the thumb side of the hand/forearm.
a. Open box of 4 x 15 plaster reinforcement sheets. Remove sheets from box and unwrap
package . Peel back the edges of (5) sheets, remove from the stack. Place on work
cart/station.
b. Place patient's uninjured thumb in opposition to the index finger.
c. Remove (1) plaster sheet from the stack of (5).
d. Place sheet next to uninjured arm to obtain sheet length.
NOTE: To increase patient cleanliness the sheet does not have to rest on the hand/forearm
e. Draw a horizontal line on each side of the plaster sheet at the base of the thumb
f. Place sheet on stack , cut the outlined pattern and excess length for all sheets, and place on
work cart/station for later use.
NOTE: The lines at the base of the thumb are designed for the splint to lay flat on the cast.

NOTE: Discard excess materials in the trash receptacle.
10. Prepare plaster reinforcement sheets for the posterior aspect of cast.
