Exam: Casting & Splinting
Bi-valving - ✔️✔️Involves cutting the cast as for removal, and slightly separating edges
with a cast splitter. Used when causing discomfort but NOT compromising NV status
Cast padding, AKA - ✔️✔️Webril
Temperature of H20 used: - ✔️✔️-Warmer increases the heat given off by plaster.
-Affects setting time
-Cold water takes longer to set
Airplane splint - ✔️✔️Holds arm in position of abduction @ shoulder level. Forearm in
flx, strut used for support.
Munster cast - ✔️✔️AKA supracondylar cast: Limits suppination and portion of arm
w/out completely prevention flx/ext of elbow. Applied in manner of long arm cast, but
cast is extended just above distal biceps. Once hardened, prox portion is trimmed
around elbow jt. Pt compliance is crucial, bc of amy of movement cast allows. Helps
prevent stiffness, but immob is still important.
Uni-valving - ✔️✔️Involves making a single cut in the cast. Used when causing
discomfort but NOT compromising NV status.
Valving should be used if..... - ✔️✔️....surgery is in the near future.
....pt is uncomfortable, but NV status is intact.
Plaster casts are made from.... - ✔️✔️....rolls of dry muslin that have been coated with
CALCIUM SULFATE.
Setting - ✔️✔️Feels hard in 10-15mins.
Truly takes 24-48hrs.
Delbert cast - ✔️✔️Short leg cast. Prevents lateral movement, allows DF/PF. Applied
then trimmed away from anterior and posterior ankle and heel.
Dehne cast - ✔️✔️AKA three-finger spica cast: used to tx navicular fx's. Section that
covers the thumb, separate section enclosing index and middle fingers.
, Cast removal - ✔️✔️Mark on cast.
Avoid cutting over bony prominences.
Making cuts on opposite sides.
Retract, don't drag the saw.
Use spreader tool, then bandage scissors for padding.
Short leg cast - ✔️✔️TX: foot, ankle fx's
Proximal end must stop below tibial tubercle to prevent damage/irritation to tibial
tubercle and patellar tendon. Distal end covers plantar surface of foot, extends to MT
heads. Toes exposed. Ankle @ 90* to prevent tightening of Achilles. Additional layers of
casting tape applied around heel to prevent cast breakdown.
PAD WELL: medial, lateral malleoli; care around anterior ankle joint, heel.
Long arm cast - ✔️✔️TX: unstable wrist fx's, radial+ulnar fx's
Extends to at least mid-biceps. Elbow @ 90*. Forearm in neutral. Prevents wrist flx/ext,
eliminates radial-ulnar suppination and pronation. May be used for non-adherent pt's, or
younger pt's who can't muscularly support a short arm cast.
Windowing a cast - ✔️✔️Allows monitoring of underlying wounds.
Diagram area before applying cast. After applying, carefully cut window utilizing wide
margins. Margin of padding left to protect window'ed skin. Padding reapplied over
window'ed area, cast shell placed back on, held in place w/ACE wrap.
Long leg cast - ✔️✔️TX: non-displaced fx's of lower leg and knee
Extends from upper thigh to MT heads. Knee @ 15-20* flx. (prevents lower leg from
rotating, permits ambulation w/crutches as leg can swing freely)
Advantages of Fiberglass - ✔️✔️-Ligher
-More comfortable
-More durable (less likely to need repair/replacement)
-More radioluscent
-More water resistant (padding still gets wet)
----> MORE EXPENSIVE :\
Long leg cylinder cast - ✔️✔️TX: anterior knee injuries -- patellar fx, quad tendon
rupture, patellar tendon rupture
Mid-thigh to Achilles tendon. Knee @ full ext. To prevent slipping, add extra padding at
proximal end. Mold above knee to keep from sliding down.
PAD WELL: distal end to protect Achilles
